Clinical experience with the use of two-dimensional ultrasound examination of the paranasal sinuses in sinusitis in outpatient practice. What does a sinus ultrasound show? Make an ultrasound of the sinuses

Not every person has heard about such an interesting study as an ultrasound of the maxillary sinuses and other sinuses. In fact, this is a fairly long-used and simple diagnostic. In our article we will talk about this research method.

What does a sinus ultrasound show?

We are all used to the fact that ultrasound is an image of an organ or tissue on the screen of the device. Ultrasound of the paranasal sinuses is called echosinusoscopy and, strictly speaking, this is absolutely not the ultrasound that everyone is used to.

The thing is that ultrasound cannot penetrate certain media. Such media and tissues include cavities with gas, for example, lungs, intestinal loops, or bone. In children of the first year of life, an ultrasound examination of the brain can be easily performed by placing the sensor on a natural opening in the skull - the fontanel.

In adults, the bones of the skull are very dense, so it is impossible to get an image of the organs and structures hidden under them. These intraosseous structures include the paranasal sinuses. Therefore, by placing the sensor on the skin in the projection of the sinuses - frontal or maxillary, we will not get the very expected picture on the screen. Moreover, this research method is not suitable for scanning deeper sinuses - sphenoid and ethmoid.

The question reasonably arises - why do we need echosinusoscopy? Of course, a more accurate picture of the contents of the cavity can be obtained with computed tomography, x-ray of the skull or. Sinus endoscopy is an excellent method for examining the inside of the sinuses. However, all these techniques are quite complex, many of them have limitations and certain hazards during pregnancy and childhood.

Advantages of Ultrasound

Even speaking about the simplest echoscopy procedure, there are several obvious advantages:

Absolute security. Ultrasound does not have a damaging effect on the human body. An ultrasound of the sinuses of a child or a pregnant woman can be carried out absolutely safely.
Can be used as many times as needed. They try to use this technique for dynamic observation or control of the treatment process.
Ease of use. Ultrasound examinations do not require special techniques. A simple ultrasound machine and a competent specialist are enough.
Cheapness. Compared to computed tomography or magnetic resonance imaging, ultrasound is considered to be much cheaper and more accessible.
Research speed.

Ultrasound technique

How is this research done? The patient is lubricated with a special acoustic gel in the projection area of the sinuses - above the maxillary or frontal sinuses, and a sensor is attached to them. As a rule, the device should be set to the simplest diagnostic option - A-mode. During the examination, the doctor tilts the patient's head in different directions. This is done so that the fluid or pus, if present in the sinus, is displaced. In such cases, the path of the wave or beam of ultrasonic rays changes.

As we have already said, during the echo examination of the paranasal sinuses, we will not see the usual gray-white picture on the screen. An echosinusoscopy or ultrasound of the sinuses is a graphical representation in the form of a curve, which is evaluated by the doctor. Such a curve is obtained in the course of recording the course of a beam of rays deviating due to different properties of the media. Ultrasound is reflected from some media, and absorbed by others. This is how the graph is formed. If there are abnormal formations in the sinus cavity: fluid, polyps, foreign bodies, and so on, the beam will change its direction and speed, and the curve will change. That, in fact, is the whole principle of echoscopy.

Of course, the value of this study is incomparable with CT, MRI or X-ray. It is rather an absolutely safe express method for diagnosing certain conditions and diseases of the sinuses.

What does echosinusoscopy show?

We list an approximate list of diseases of the sinuses of the nose, in which the use of ultrasound is effective:

Volumetric formations of the sinuses: polyps, cysts, foreign bodies.
The presence of inflammatory fluid or.
Control of the dynamics of the disease and treatment: changes in the level of fluid and volumetric formations.

Basically, this study is used by "problem" categories of patients: children and pregnant women as a starting point in diagnosis. Of course, if any serious process is suspected, the patient will be recommended a clarifying study - X-ray, computed or magnetic resonance imaging.

Pathology of the paranasal sinuses (SNP) in recent years has come out on top in the structure of diseases of the ENT organs, and the proportion of maxillary sinusitis among other sinusitis is 56-73%. With different types of acute and chronic sinusitis, an otolaryngologist most often deals with outpatient appointments, so the issues of diagnosing these conditions are extremely important.

The most common symptoms of sinusitis are facial pain, difficulty in breathing through the nose, purulent discharge from the nasal cavity, and impaired sense of smell. More often pains are localized in the frontal region, less often in the zone of projection of the maxillary sinus, sphenoiditis is characterized by pains in the back of the head and in the depths of the head, the appearance of an unpleasant odor in the nose, flickering flies before the eyes, impaired convergence, decreased vision, dizziness, nausea and even vomiting. These symptoms are due to the location of the sphenoid sinus at the base of the skull and the close proximity of the brain, optic, trochlear, oculomotor and abducens nerves. It is known that monosinusitis - the defeat of one sinus - is a rare pathology. With sinusitis, as a rule, there is a lesion of several sinuses at the same time, and the symptoms of the pathological process in any sinus may prevail, masking the lesion of other paranasal sinuses.

Certain problems arise in the differential diagnosis of sinusitis with allergic rhinitis, which is often accompanied by significant swelling of the mucous membrane of the paranasal sinuses.

Traditional in the diagnosis of sinusitis are anterior rhinoscopy, plain radiography and diagnostic puncture of the maxillary sinus, as well as bacteriological and cytological examination of secretions from the nasal cavity, in some cases diaphanoscopy is used.

Anterior rhinoscopy makes it possible to judge the presence of sinusitis when a mucopurulent secret is found in the region of the middle nasal passage, but its absence does not exclude the pathological process in the sinuses.

Diaphanoscopy (transillumination), when compared with plain radiography, often gives false negative results, its use is limited to the maxillary and frontal sinuses and cases of edema of the sinus mucosa.

Optical endoscopy of the nasal cavity has gained significant popularity in recent years. The method refines the data of standard diagnostic techniques, helps to investigate the patency of sinus fistulas, but does not provide direct information about their contents.

Infrared thermography, microwave radiometry, histography, for various reasons, have not found wide application in practice; rhinomanometry is designed to study the function of nasal breathing and supplement the information obtained by imaging methods.

Diagnostic puncture of the maxillary sinus is widely used and allows you to get the contents of the maxillary sinus or prove its absence, however, this method does not give an idea of the state of the walls and mucous membrane of the sinus, the presence of polyps and other formations in it. In addition, the negative quality of this method is its invasiveness.

Plain radiography is the most common method for diagnosing SNP pathology, despite the fact that the cells of the ethmoid labyrinth and the sphenoid sinus are limitedly available to it. Often the method gives false positive results in the study of the maxillary and frontal sinuses. The frequency of discrepancy between the results of plain radiography and computed tomography ranges from 23 to 74%.

Computed tomography is the gold standard in the diagnosis of sinusitis, providing information on the spatial relationship of the intranasal structures and all paranasal sinuses, computed tomography serves as a map for planning surgical intervention. However, this method is quite expensive, so its use in everyday practice is inappropriate for detecting banal forms of sinusitis and monitoring during conservative treatment.

At the same time, there are many examples when none of the methods of radiation diagnostics can be applied, but it is necessary to assess the condition of the SNP. This applies especially to cases of acute or chronic sinusitis in pregnant women, in patients who have just undergone other x-ray studies. In addition, sometimes patients fundamentally refuse x-ray examination. In such a situation, the method of choice is the ultrasound examination of the SNP.

Ultrasound scanning in A-mode using a sinuscope has been used in otolaryngology for a long time and in experienced hands has an accuracy of 76 to 90%, although it often does not allow differentiating a volumetric formation inside the sinus (cyst, polyp, mucocele) from mucosal edema and fluid component . Diagnostic errors in this pathology are possible in 9 out of 10 cases due to difficulties in interpreting the data obtained, in addition, the A-method does not allow to establish the nature of the secret and its consistency.

B-mode paranasal sinus ultrasound (US) provides 2D polypositional imaging not only of the paranasal sinuses, but also of other bony structures and soft tissues, resulting in better topographic orientation and interpretation than A-method. The results of ultrasound in 100% of cases coincide with the data of the survey radiography. So, according to V.V. Shilenkova et al. , Ultrasound is an alternative to plain radiography in the initial diagnosis of sinusitis of the maxillary sinus.

The aim of this work was to evaluate the clinical significance of B-mode ultrasound of the paranasal sinuses in the primary diagnosis and monitoring of conservative treatment of sinusitis in conditions where plain radiography and computed tomography cannot be used, in particular, during pregnancy.

Material and methods

The study included 26 patients (25 women and 1 man) aged 26 to 60 years (mean age 34.6±3.2 years) who applied for a consultation with an outpatient otolaryngologist, who underwent an ultrasound examination of the paranasal sinuses in connection with the fact that 23 patients were pregnant (from 16 to 33 weeks), 2 patients underwent X-ray examination of the lungs on the day of treatment or the day before, 1 patient refused X-ray examination. All patients at the time of treatment were worried about nasal congestion (26 people), 17 - mucous discharge, 11 - mucopurulent discharge from the nose and nasopharynx. 23 patients complained of headache, 15 patients had subfebrile temperature (37.2-37.4°C). On examination, in all cases, swelling of the turbinates of varying degrees, mucous or mucopurulent discharge in the nasal passages were noted, in 11 cases - deviated nasal septum, in 5 - adenoid vegetations in the dome of the nasopharynx. One woman had previously been operated on for polyposis sinusitis, two had suffered from chronic catarrhal sinusitis for the past 3 years. Clinical data required the exclusion of acute or exacerbation of chronic sinusitis.

Ultrasound was performed on modern ultrasound scanners with linear sensors with a frequency of 7.5 MHz with a working surface length of 37-40 mm in two mutually perpendicular projections: sagittal and horizontal, in a sitting position facing the doctor.

The study was carried out according to the method of V.V. Shilenkova et al. and began with an examination of the maxillary sinus in the sagittal projection. Finding the lower wall of the orbit, which is the upper wall of the sinus, serves as a guide when searching for the sinus itself. The transducer was moved medially and laterally to examine the corresponding side walls of the sinus. At the second stage, to obtain horizontal slices, the sensor was moved parallel to the lower edge of the orbit from top to bottom, while taking into account that the distance to the posterior wall of the maxillary sinus decreases when moving from the bottom of the orbit to the alveolar process.

To examine the frontal sinus, scanning was started in the horizontal plane from the bridge of the nose, then sagittal sections were obtained.

The normal ultrasound picture of SNPs is characterized by the absence of visualization of their posterior walls as a result of natural pneumatization (Fig. 1).

Rice. one. Sonographic picture of the maxillary sinus is normal, sagittal section: a - skin, b - soft tissues, c - air, thin arrows - anterior wall of the sinus.

The frontal sinus is located in the thickness of the frontal bone, in 10-15% of patients it may be absent, it has 4 walls: the lower orbital - the thinnest, the anterior - the thickest (up to 5-8 mm), the posterior, separating the sinus from the anterior cranial fossa and the internal - partition. The volume of the sinus varies from 3 to 5 cm³. The maxillary sinus is located in the body of the maxillary bone and is an irregularly shaped pyramid with a volume of 15 to 20 cm³.

The bone base of the anterior or facial wall of the maxillary sinus has a depression called the canine or canine fossa, and is visualized as a concave hyperechoic line, beyond which no structures are normally defined.

The soft tissues of the canine fossa are represented by skin, subcutaneous fat, and mimic muscles (Fig. 2). The most superficial is m. levator labii superioris alae nasi, running from the inferomedial edge of the orbit to the upper lip, only its abdomen is visible on the echogram, since the place of discharge remains outside the cut. The middle position is occupied by m. levator labii superioris, starting from the entire infraorbital edge of the upper jaw, the muscle bundles converge downward and enter the thickness of the muscle that raises the corner of the mouth and the wing of the nose. The deepest is m. levator anguli oris, starting from the bottom of the canine fossa and attaching to the corner of the mouth.

Rice. 2.

Below the place of origin m. levator labii superioris hyperechoic line, which is a reflection of the bone surface, has a small "defect" corresponding to the infraorbital foramen (foramen infraorbitalis), through which the nerve and artery of the same name exit the infraorbital canal.

The upper wall of the maxillary sinus simultaneously represents the lower wall of the orbit, its position is quite well determined due to the visualization of the orbit (Fig. 3).

Rice. 3.

The posterior wall of the maxillary sinus borders on the cells of the ethmoid labyrinth and the sphenoid sinus, its most distant point is located at a distance of 27 to 34 mm from the anterior wall, the medial wall is the lateral wall of the nasal cavity, the lower one is formed by the alveolar process of the upper jaw and is characterized by a close arrangement of the roots of the teeth to the sinus cavity. In some cases, the tops of the roots of the teeth stand in the lumen of the sinus and are only covered by the mucous membrane, which can contribute to the development of odontogenic infection of the sinus and the ingress of filling material into its cavity.

Visualization of the posterior wall is possible only if the pneumatization of the sinus is impaired and depends on the amount of secretion or other contents: the less air in the sinus, the more complete the view of its walls will be. It should be borne in mind that sometimes on the walls of the sinus there are bone scallops and bridges that divide the sinus into bays and very rarely into separate cavities.

results

In 8 patients, according to the results of ultrasound, the pathology of the SNP was not revealed. In 18 cases, acute maxillary sinusitis was established: in 14 patients - with a thickening of the sinus mucosa, including 2 with the presence of cysts, another 2 with the presence of polyps; in 6 patients - with the presence of exudate (in 1 woman with hyperechoic inclusions, which turned out to be filling material during additional examination). Frontal sinusitis with thickening of the frontal sinus mucosa was diagnosed in 3 patients.

Taking into account the ultrasound picture, appropriate treatment was selected and carried out. In the course of therapy, all examined patients underwent ultrasound of the SNP, which made it possible to evaluate its effectiveness and make the necessary adjustments. All cases of acute sinusitis ended in recovery, with chronic processes, remission was achieved. Subsequently, 5 patients after childbirth underwent computed tomography of the SNP, which confirmed the presence of cysts in 2 cases, polyps in 2 and filling material in the maxillary sinuses in 1 patient.

With swelling of the mucous membrane of the maxillary sinus behind its anterior wall, the appearance of a zone of reduced echogenicity of a homogeneous structure with a fairly clear distal contour with a thickness of 0.5 to 1.6 cm is noted (see Fig. 2).

The horizontal line of separation of media, which would correspond to the X-ray concept of "liquid level", is not visible with ultrasound, since the ultrasonic beam passes parallel to this boundary, no matter how we move the sensor. Consequently, the amount of exudate in the cavity has to be judged by the extent of visualization of the posterior wall, which corresponds to the level of fluid in the sinus (see Fig. 3, 4). An important detail of ultrasound is the correct position of the patient's head, it should not be tilted back, since in this case the secret in the sinus moves to the back wall, an air gap appears between the front wall and the secret, creating conditions for obtaining a false negative result.

Rice. four.

In the study in dynamics against the background of treatment, as the amount of exudate in the sinus decreases, the extent of visualization of the posterior wall decreases up to its complete disappearance, which corresponds to the restoration of pneumatization.

If there is a cyst in the maxillary sinus (Fig. 5), one of the ultrasound symptoms may be a change in the contour of the anterior wall of the sinus, which becomes convex due to alignment with the anterior wall of the cyst. The posterior wall of the cyst is seen as a hyperechoic line that has a curvature, in contrast to the distal contour of the thickened mucosa, which follows the relief of the anterior wall of the sinus.

Rice. 5. Sonographic picture of the cyst of the maxillary sinus, horizontal section: a - skin, b - soft tissues, c - air, thin arrows - the anterior wall of the cyst, thick arrows - the posterior wall of the cyst.

Heterogeneous contents of the sinus, when grouped or scattered hyperechoic inclusions are visualized against the background of a thickened mucous membrane or exudate, which do not disappear during repeated studies, is an indication for subsequent computed tomography to exclude polyposis or the presence of foreign bodies (filling material), which are often an etiological factor in the development of sinusitis .

conclusions

In the primary diagnosis and monitoring of the conservative treatment of sinusitis in a polyclinic, when plain radiography and computed tomography cannot be used for one reason or another, in particular in pregnant women, ultrasound examination of the paranasal sinuses in B-mode is the safest, non-invasive diagnostic method that provides an important information for clinicians and should be used on an outpatient basis in all cases.

Ultrasound of the maxillary sinuses- a highly specialized examination used in the treatment of ENT diseases. Nasal ultrasound is an affordable and safe alternative to x-rays and computed tomography of the maxillary sinuses, but ultrasound is not always as informative as the above examinations.

With the help of ultrasound of the nasal sinuses, it is possible to determine the presence of fluid or pus in the nasal cavities, the condition of all structures (including vascular septa, cartilage tissue), the presence of neoplasms of a different nature, foreign objects.

The procedure is completely painless, non-invasive and safe. It can be performed on patients of any age without restrictions, including children and pregnant women. You can make an ultrasound of the nose of a child at any age.

Indications

Ultrasound examination of the maxillary sinuses is effective for diagnosing pathologies of the nasal septum, identifying foci of inflammation in sinusitis, frontal sinusitis, rhinitis, sinusitis. Ultrasound of the nasal cavity is used to study the causes of nosebleeds, allergic reactions, in the presence of polyps, lipomas, the consequences of mechanical damage, as well as in dental practice.

Training

The session itself lasts 10-15 minutes, no preparation is needed. If necessary, ultrasound of the maxillary sinuses is prescribed repeatedly to track the dynamics of treatment or combined with other diagnostic examinations.

Price

The cost of ultrasound of the maxillary sinuses in Moscow ranges from 600 to 6200 rubles. The average price is 1410 rubles.

Recently, ultrasound examination (ultrasound of the sinuses) for sinusitis has become popular. Ultrasound has become a tool for diagnosing acute sinusitis over the past two decades.

Ultrasound of the nose and paranasal sinuses

Sinus ultrasound is a safe, fast, non-invasive, inexpensive and repeatable method for examining diagnostics, which is also commonly called echosinusoscopy.

Echo-sinusoscopy is very sensitive in detecting fluid in the sinus. It was registered in otolaryngology (ENT) - the accuracy of determining sinusitis was more than 90%. An ultrasound examination of the sinuses is performed quickly and painlessly. This procedure is not expensive and is available to every patient.

Accurate diagnosis of sinusitis is challenging because the signs and symptoms of sinusitis are nonspecific and it is not always easy to distinguish between rhinitis and sinusitis. Investigations such as those that make an accurate diagnosis are not commonly used to diagnose uncomplicated sinusitis in the outpatient setting due to additional cost, time, and radiation risk. That is why ultrasound of the sinuses is relevant today.

Indications for ultrasound examination

With the help of an ultrasound machine, the maxillary sinuses are clearly visible. They are located under a layer of soft tissues, through which the sensor can easily view the inflammatory process and the presence of fluid in them. For diagnosing the frontal sinuses, it is better to use. They are located under the frontal bone, through which the ultrasound machine's sensor will not be able to examine.

Indications for ultrasound of ENT organs:

Acute and chronic form of the disease of ENT organs.
Runny nose as a manifestation of an allergic reaction.
Injured nasal septum.
Polyposis disease.
Malignant and benign neoplasms in the nasal passages.
The presence of a foreign body in the nasal passages.
Furunculosis.
Other injuries of the nose.
Frequent headaches.
For the purpose of observation in the treatment of ENT diseases with medications.

Ultrasound with sinusitis of the maxillary sinuses

A specialist may prescribe an ultrasound if the patient is suspected of having a disease - sinusitis. However, most often, doctors use the X-ray method of research in the acute and chronic form of ENT diseases.

Conducting ultrasound with sinusitis

Ultrasound examination in the presence of sinusitis can be prescribed to patients in childhood or pregnant women, the category of persons for whom frequent exposure to x-rays is undesirable.

Methodology for the study of ultrasound of the paranasal sinuses

Ultrasound of the paranasal sinuses is carried out both on stationary equipment and on movable equipment.

The convenience of a mobile echosinusscope is that the doctor himself can come to the ward or to the patient's house, conduct an examination and issue a conclusion. A popular echosinusscope among doctors today is Sinuscan (Sinuscan - 201)
The advantage of ultrasound equipment in a hospital lies in its information content. The doctor-diagnostician sees the results of the examination on a large monitor and makes a diagnosis much more accurately. In medical slang, this equipment is called ENT-Combine.

Ultrasound of the sinuses in the hospital

Step-by-step examination of the paranasal sinuses using ultrasound in a hospital:

The specialist conducts a conversation with the patient and explains to him the course of the upcoming ultrasound.
The patient is seated in a specialized chair for further examination.
The doctor lubricates the skin in the area of the paranasal sinuses with a specialized gel. This is necessary so that the device can better view the sinuses.
The specialist guides the linear sensor over the skin in the area of lubricated areas.
During the examination, the doctor tilts the patient's head to the sides in order to accurately view the sinuses for the presence of fluid or purulent contents.
After a complete examination, the doctor writes a transcript of the resulting curved line.
The patient cleans the skin from a special gel and awaits the result of the study for a further trip to the doctor and the appointment of a qualified treatment if necessary.

Features of using the echosinusscope Sinuscan (Sinuscan - 201)

Echo-sinusoscope Sinuscan 201

This ultrasound machine is manufactured using the latest technology. It is small in size, which allows it to be used in the patient's room. The study time takes several minutes. The rays penetrate to a depth of up to eight centimeters. They allow you to scan the frontal and maxillary sinuses for the presence of accumulated fluid. A scale is visible on the built-in small screen. The image changes to a graphic curve in the presence of fluid or pus in the sinuses.

The echosinuscope has built-in memory for four studies. The device can be operated with the left or right hand, according to the desire and convenience of the specialist. The kit includes a charger, a specialized gel and a case for carrying and storing.

The course of the procedure:

The patient is informed about the progress of the upcoming study.
He takes a lying or sitting position at the request of the doctor.
The specialist wets the sinus area with a special gel.
Starts the Sinuscan.
Attaches to the sinuses and leads with an echosinusscope within their borders.
According to the results displayed on the screen, the doctor decides on the result of the diagnosis.

Examination with the echosinusscope Sinuscan 201 - fast, painless and effective.

The cost of an examination with Sinuscan 201 is estimated at 300-500 rubles

Deciphering echosinusoscopy

What does the ultrasound protocol show?

The presence of foreign bodies in the nasal passages and sinuses.
Malignant and benign neoplasms.
cystic disease.
Accumulated fluid or purulent contents in the maxillary sinuses.
Examination of the course of the disease and the effectiveness of the treatment prescribed by the specialist.

Echosinusoscopy is most often prescribed for women during pregnancy, children and nursing mothers. In the absence of contraindications to radiographic diagnostics, patients will be assigned the names of this type of study. A good picture of the disease is visible during computed tomography and magnetic resonance therapy, but these procedures are expensive and not prescribed to all people with diseases of the ENT organs.

Ultrasound or x-ray of the sinuses

Type of examination	Positive diagnostic criteria	Negative diagnostic criteria
ultrasonic	Ultrasound examination does not have a detrimental effect on the human body, it can be carried out by women during pregnancy and during the natural feeding of the baby. Also, the device is equipped with dopplerography, which allows to assess the condition of large vessels in the nasal passages. This method of diagnosis can be carried out at a low cost in almost every clinic or private clinic. The result is issued by the doctor immediately after the examination.	Ultrasound is rarely used to diagnose ENT organs. Most practitioners are not qualified to conduct examinations with this machine. Ultrasound helps to view the maxillary sinuses for the accumulation of fluid in them, the frontal sinuses are protected by a wide bone, it is almost impossible to view them through the equipment. Often, an ultrasound examination shows the presence of an inflammatory process, which is actually not present, and the patient is prescribed antibiotic therapy. To get an accurate picture of the disease, it is necessary to conduct an ultrasound examination several times, which takes time and increases the cost of funds.
radiographic	X-ray examination is carried out in diseases of the ENT organs more often than ultrasound. Most doctors trust this device more.	When taking frequent x-rays, there is a possibility of irradiation of the human body. This diagnosis cannot be carried out during pregnancy, as it can provoke abnormal development of the fetus.

Ultrasound of the sinuses of the child

Nasal ultrasound is possible from 2 years

Ultrasound of the paranasal sinuses has no contraindications and therefore this type of diagnosis is prescribed for young patients suffering from diseases of the ENT organs.

The study is unacceptable for children under the age of two years.

The doctor can prescribe a diagnosis of the frontal sinuses and maxillary sinuses, as they are already formed and ready for examination. The rest are formed before the age of twelve, and it is almost impossible to consider pathological changes in them.

The procedure is painless, which parents and children need to talk about when going to the doctor. The course of diagnosis is carried out in a sitting or lying position at the discretion of the specialist. The duration of the examination, taking into account the waiting for the results, is no more than thirty minutes.

Clinics and prices where ultrasound of the sinuses is done

Sinus ultrasound is performed both in public clinics and in private clinics in large cities. The price of diagnosis depends on the location and qualifications of the specialist. The approximate cost is from 500 to 1550 rubles.
