RESUMEN
Vestibular neuritis occupies the third place in terms of prevalence in the structure of peripheral vestibulopathies, therefore, the choice of optimal diagnostic and differential diagnostic tactics at different stages of the disease is an urgent task. OBJECTIVE: To optimize the diagnostic algorithm for vestibular neuritis based on an assessment of the sensitivity of clinical methods for studying vestibular function in the recovery period of the disease. MATERIAL AND METHODS: A comprehensive assessment of the sensitivity of clinical methods for the study of vestibular function in the acute (up to 14 days: at the time of initial treatment, on the 7th and 14th day) and subacute (up to 3 months: on the 28th and 90th day) periods of the disease in 52 patients with upper vestibular neuritis was carried out. RESULTS: The timing of the processes of restoration of vestibular function after a transferred vestibular neuritis is individual: after 14 days, restoration of vestibular function was recorded in 52% (n=27) patients, after 1 month - in 62% (n=32), after 3 months - in 71% (n=37) patients with upper vestibular neuritis. Statocoordination, statokinetic, oculomotor tests under visual control have the highest sensitivity in the acute period of vestibular neuritis, within up to 7 days from the onset of symptoms. In the subacute period of vestibular neuritis, the study of spontaneous nystagmus and nystagmus in the head shaking test retains high sensitivity only when using special tools (Frenzel goggles or videonystagmography). A decrease in the sensitivity of the head rotation test and the dynamic visual acuity test in the subacute period of vestibular neuritis is associated with the processes of central compensation and the formation of a latent saccade. CONCLUSION: The sensitivity of clinical tests in patients with vestibular neuritis depends on the timing of the examination.

Data on the state of sense of smell in patients who had a new coronavirus infection caused by the SARS-CoV-2 virus are currently reduced because of the impairment of the olfactory nerve system. There are practically no results in studies of disorders in the trigeminal nerve system. OBJECTIVE: Qualitative assessment of olfactory disorders after COVID-19 according to the system of olfactory and trigeminal nerves with a targeted assessment of the functional component of olfactory disorders. MATERIAL AND METHODS: We examined 40 patients aged 19 to 66 who had a coronavirus infection. All patients underwent neurological, otorhinolaryngological examinations, olfactometry, filled out the hospital anxiety and depression scale. RESULTS: Anosmia was diagnosed in 5 (12.5%) patients, hyposmia in 21 (52.5%) patients, and normosmia in 14 (35%) patients. Formed: the 1st group - 14 patients (35%) with normogram according to olfactometry; the 2nd group - 26 patients (65%) with anosmia/hyposmia. In the 1st group, disorders of the anxiety-depressive spectrum were significantly more common. In the 2nd group, a low identification of odors was found, lying in the spectrum of fresh, sharp, unpleasant, irritating, compared with sweet and pleasant or neutral, which indicates a predominant lesion of the trigeminal system. CONCLUSION: In patients with complaints of impaired sense of smell after undergoing COVID-19, the possible functional nature of anosmia/hyposmia should be taken into account, which requires the referral of such patients to psychotherapeutic specialists, and the possible entry of olfactory disorders into the 'trigeminal' spectrum.

This article describes a rare case of necrotic xanthogranuloma in a 46-year-old patient who presented with the development of periorbital xanthelasms, progressive bilateral sensorineural hearing loss and bilateral vestibulopathy, followed by multiple myeloma and amyloidosis. For several years, the patient underwent standard rehabilitation for chronic sensorineural hearing loss and was fitted with a hearing aid. During hospitalisation for exacerbation of chronic bronchitis, monoclonal gammopathy was identified, and later, after careful examination and repeated biopsies, necrotic xanthogranuloma, multiple myeloma and AL-amyloidosis were confirmed. Targeted immunochemotherapy resulted in improvement of hearing and significant recovery of the vestibuloocular reflex bilaterally.

The literature review presents approaches to the management of patients with vestibular disorders. The principles of organization of vestibular rehabilitation in peripheral vestibular hypofunction, indications for appointment, factors influencing its implementation, technique, methods of evaluating effectiveness are considered in detail. Attention is drawn to the fact that the selection of exercises and the duration of vestibular rehabilitation is carried out individually and depends on many factors, including the nature of vestibular deficiency and the specific characteristics of the patient. The possibilities of using additional pharmacological therapy with histamine preparations, which can accelerate the onset of vestibular compensation, are shown. It is noted that vestibular rehabilitation is a safe and effective method of treating peripheral vestibular hypofunction and should be recommended to patients of all ages with vestibular disorders leading to limited social and physical activity.

The study of vestibular function in patients with Meniere's disease (MD) is an urgent task, since it influences the choice of treatment tactic. We evaluated the results of caloric and video head impulse (vHIT) tests in 76 patients who met the clinical criteria for significant Meniere's disease (AAO-HNS modified by the Barany Society, 2015). Dissociation of the results of caloric and vHIT tests is observed in the majority (74%) of patients with MD: at normal gain, according to vHIT data, hypofunction of peripheral vestibular structures is recorded according to the caloric test (KASL 47 ± 7.8%). In patients with MD, vestibular dysfunction is observed mainly at low frequencies (0.003 Hz), therefore vHIT, which allows assessing horizontal semicircular canal function at high frequencies (3-5 Hz), is not an optimal study for assessing the degree of vestibular dysfunction in patients with MD.

The results of magnetic resonance imaging (MRI) of the inner ear 24 hours after intratympanic administration of 1 ml of diluted (1:7) contrast substance for gadolinium-based MRI in 43 patients with moderate and severe Meniere's disease course are presented. It has been revealed that in case of severe and moderate course of Meniere's disease endolymphatic hydrops is presented in all departments of labyrinth: cochlea, vestibule, semicircular canals, but is most pronounced in vestibular department of labyrinth: horizontal semicircular canal and vestibule. The neuroimaging method according to the presented protocol is safe and can be applied in a wide practice both to assess the presence and localization, and the degree of expression of the endolymphatic hydrops.

The literature review is devoted to the effects arising from the effect of a cochlear implant on the vestibular system. Due to the pronounced anatomical proximity and physiological interaction of vestibular receptors with the cochlea, the installation of a cochlear implant and its electrical activity are associated with an effect on the vestibular system. The analysis of the works of foreign and domestic researchers who carried out monitoring of vestibular function in patients after cochlear implantation using modern objective methods was carried out.

The results of a comprehensive examination of 82 patients with clinical signs of definite Ménière's disease, unilateral lesion and confirmed by extratympanic electrocochleography endolymphatic hydrops are presented. The results of the study showed that only 38% of patients had cochleovestibular syndrome due to Ménière's disease. In 45% of patients, Ménière's disease was combined with other diseases: benign paroxysmal positional vertigo, vestibular migraine, persistent postural-perceptual dizziness, superior semicircular canal dehiscence. In 17% of patients cochleovestibular syndrome was due to other reasons: vestibular migraine, tumor of the posterior cranial fossa, superior canal dehiscence syndrome, Cogan's syndrome, enlarged vestibular aqueduct, otosclerosis. Complaints, medical history of the disease and life, brain MRI, temporal bone CT and pure tone audiometry in dynamics are important in suspected Ménière's disease. For 1 and 2 Ménière's disease stages the most important characteristic are: progressive unilateral sensorineural hearing loss and reduced slow faze velocity values of caloric nystagmus in dynamics, mainly in warm response if attacks of vertigo is maintain; normal head impulse test between vertigo attacks and pathological result of this test in attack of vertigo with the normalization of gain during the first day.

OBJECTIVE: To identify etiology, clinical symptoms of bilateral vestibulopathy (BV) depending on etiology. RESULTS: Idiopathic BV was identifies in one third of patients. The most common identified reasons are Meniere's disease, meningitis and ototoxicity. BV develops more often without incidental hearing loss in case of idiopathic, autoimmune etiology, ototoxicity and bilateral vestibular neuronitis. BV after neuroinfection is characterized by prompt symptoms development, bilateral severe hearing loss, Gain reduction in vHIT lower 0.4 and loss of more than 8 lines in DVA test. CONCLUSION: BV after bilateral Meniere's disease is characterized by Gain higher than 0.4 and typical clinical picture of the primary disease.

PURPOSE: To analyze the effectiveness of various methods of treating dizziness with fistulas of the labyrinth (FL) of inflammatory genesis. An analysis of the surgical treatment of 216 patients with chronic suppurative otitis media (CSOM) with cholesteatoma complicated by FL using a variety of FL treatment methods is presented. All patients underwent a debridement operation on the middle ear or revision of the postoperative cavity: in 48 patients with a matrix of cholesteatoma in situ on the fistula, in 109 patients with matrix removal followed by plastic repair or FL filling with various autotissues, in 59 patients with matrix conservation, plastic removal or filling FL and SLD labyrinth. In the last two groups, filling of a semicircular canal (SC) defect was performed in 33 patients, and mastoidoplasty - in 47. CONCLUSION: All used FL treatment techniques are effective in the treatment of peripheral vestibular disorders. Careful treatment of SC fistula after removal of all pathological conditions in the absence of active inflammation and the appointment of hormone therapy in the postoperative period are the main factors in preserving the functions of the labyrinth in any surgical technique. Filling of the lumen of the SC and mastoidoplasty in patients with CSOM with FL can eliminate peripheral dizziness.

AIM: The aim of this study is to evaluate clinical symptoms and recovery of vestibule-ocular reflex (VOR) in patients with vestibular neuronitis (VN) in dependence on severity of VOR damage according to video head impulse test (vHIT). PATIENTS AND METHODS: 45 patients with VN and superior or both superior and inferior vestibular nerves involvement were recruited and horizontal gain was measured with vHIT. According to gain asymmetry the patients were divided in three groups: 11 patients with 8-19% gain asymmetry, 10 patients with 20-39% gain asymmetry and 24 patients with more than 40% gain asymmetry. RESULTS: Coexisting chronic heart and endocrinological diseases could contribute to greater damage of VOR in VN. In patients with less gain asymmetry the full recovery of gain on the affected side was more often. When gain asymmetry was more than 40%, only 10% of patients demonstrated full recovery of gain in 8-12 months. Dynamic visual acuity (DVA) could normalize in patients with clinically significant gain asymmetry. DVA stays decreased more often in patients with in the most gain asymmetry even after vestibular rehabilitation. Benign paroxysmal positional vertigo appeared in 8.9% of patients with VN and had no correlation with VOR asymmetry. Steroid treatment didn't show significant impact on VOR recovery in patients with VN.

The results of treatment of 38 patients suffering from sensorineural hearing loss with the Gliatilin (solution 3 ml intravenously for 10 days, capsules 400 mg 3 times a day or solution for ingestion 600 mg 2 times a day for 3 months) are presented. All patients in dynamics were given a comprehensive audiological, neurological examination, as well as an assessment of psycho-emotional status and cognitive function. Subjective improvement of ear noise tolerance by patients by 40 days of observation and continuation of this trend during the whole period (100 days) outside of the form of the medicinal preparation is noted. A reliable improvement in the 50% speech intelligibility threshold by day 100 of observation was established in patients of both groups, with a tendency towards earlier (on day 70 of the study) onset of this effect when taking the drug inside as a solution. The Gliatilin has been proven to reduce anxiety and depression, as well as reliably improve cognitive function. Thus, Gliatilin (injection solution, ingestion solution, capsules) can be used to improve the subjective tolerance of ear noise, speech intelligibility and quality of life of patients in chronic sensorineural hearing loss.

The objective of the present study was to evaluate the otolith function in the patients presenting with idiopathic benign paroxysmal positional vertigo (pBPPV) attributable to the occlusion of the posterior semicircular canal (PSCC) of the inner ear with the use of vestibular evoked myogenic potentials (VEMP). Cervical (cVEMP) and ocular VEMP (oVEMP) were measured in 34 patients with idiopathic pBPPV before and 7 days after the treatment by means of reposition maneuvers. The results of the repeated Dix-Hallpike test performed 7 days after the repositioning maneuver were negative in 27 patients and positive in 7 patients. There was no statistically significant difference in the amplitude of cervical VEMP between the healthy and affected ears either before or after the repositioning treatment. The measurement of oVEMP revealed a reduction of the response amplitude on the affected side. The average values of the plnl on the healthy side were 12.84±1.09 and those on the affected side 4.62±0.69 (p<0,05). The successful repositioning treatment resulted in a significant increase of the oVEMP amplitude on the affected side (p<0,05). In the patients presenting with the persistent symptoms of pBPPV, the repositioning maneuvers did not cause an appreciable increase in the amplitude of oVEMP on the affected side (p<0.05). The results of the present study give evidence that pBPPV of the posterior semicircular canal is associated with the impairment of the function of the receptor structures of the utriculus and the preserved function of the succulus as suggested by the reduction of the oVEMP amplitude and clinically significant asymmetry of ocular VEMP on the affected side with intact cervical VEMP on both sides. The successful treatment of pBPPV of PSCC with the use of the liberatory maneuver results in the increase of the oVEMP amplitude on the affected side increases while the response asymmetry between both sides significantly decreases which indicates the repair of the utriculus otolith function.

At present, the skeptical attitude toward the term 'cervical vertigo' (CV) predominates in the ENT-community. Such point of view is attributable to the absence of specific CV symptoms and well-defined diagnostic criteria. The present literature review was designed to consider the results of the clinical observations and experimental investigations obtained during the past 150 years that give evidence of the possibility to regard cervical vertigo as a separate nosological entity. The characteristic signs of this condition are analyzed and systematized. Four CV variants are currently distinguished. The principles of diagnostics and treatment of cervical vertigo are discussed and general concept of CV is formulated.

The objective of the present work was to study the influence of the dry extract from the leaves of Ginkgo biloba EGb 761 (used as monotherapy at a dose of 120 mg twice daily during 4 months) on the vestibular function of the patients presenting with cochleovestibular pathology of peripheral and mixed genesis. We present the results obtained by the objective and subjective methods for the evaluation of the vestibular function as well as the neurological and psychoemotional state of the 40 patients that was carried out during the four months of memoplant monotherapy. It is concluded that monotherapy with the use of the dry extract from Ginkgo biloba leaves can be applied for the purpose of improvement of static and dynamic balancing state. Moreover, this memoplant preparation can be used as a means of prophylaxis of recurrent dizziness that in addition reduces the severity of anxiety and depression without producing adverse side effects.
