[Tinnitus features and masking in patients with normal hearing and with high frequency hearing loss].

Objective: To access tinnitus features and effectiveness of its masking in relation to sensorineural hearing loss (SHL), gender, age, affected side and tinnitus pitch.

Material And Methods: 53 patients (32 (60.4%) females and 21 (39.

[Cochleovestibular manifestations in coronavirus infection].

One of the main causes of the of the inner ear pathology is a viral infection including SARS-CoV-2 virus. On the other hand the psycho-emotional state of patients also affects patients with hearing loss, tinnitus and dizziness, and an increase in depression and anxiety was revealed during the period of self-isolation. Goal of our study was to analyze cochleovestibular pathology in patients with COVID-19.

[Glucocorticosteroids in the treatment of acute neurosensory hearing loss. The current state of the problem. Part 2].

Modern literature data are presented on the choice of a drug for hormonal therapy in acute neurosensory hearing loss of various origins, the doses used for systemic therapy, the features and methods of intratympanic administration of glucocorticosteroids, and the evaluation of the effectiveness of treatment with this group of drugs.

[Dissociation of the results of caloric and video head impulse tests as a marker of Meniere's disease].

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.

[Hearing and dementia: is there a link?].

The review of literature considers the correlation between hearing loss and dementia. Hearing loss is one of the few potentially modifiable factors in terms of dementia prevention, and the research highlighted in this article confirms the need to continue studying this correlation to better understand the benefits of treating hearing loss in order to improve cognitive function. It should be kept in mind that hearing loss also has social consequences in the form of reduced daily activity, communication function, isolation, loss of independence, impaired ability to drive vehicles, and this once again confirms the importance of timely treatment of hearing loss.

[Vertical downbeat nystagmus in benign paroxysmal positional vertigo].

Unlabelled: Benign paroxysmal positional vertigo (BPPV) is the most common peripheral vestibulopathy. Ppatients with BPPV contact with otorhinolaryngologists in 25% of cases. Due to the polymorphism of this pathology, an urgent task is to asess differential diagnosis of BPPV with various variants of the central positional syndrome: vestibular migraine, myofascial cervical syndrome, organic changes in the structures of the cerebellum.

[The compensation of the vestibulo-ocular reflex during rehabilitation of the patients presenting with vestibular neuritis].

Aim: The objective of the present study was to elucidate the mechanisms behind the compensation of the vestibular ocular reflex and evaluate the effectiveness of vestibular rehabilitation in the patients presenting with vestibular neuritis (VN) with the application of the video head-impulse test (vHIT) and the dynamic visual acuity test (DVAT).

Methods: The study included 26 patients with vestibular neuritis whose condition was assessed by scoring based on the dizziness handicap inventory, the dynamic visual acuity test, and the video head-impulse test with the evaluation of saccades and the degree of eye-head movement coordination (gain) before and after the course of vestibular rehabilitation.

Results: The study has demonstrated that the course of vestibular rehabilitation of the patients presenting with vestibular neuritis resulted in a significant decrease in the scores of dizziness estimated based on the dizziness handicap inventory and an improvement of dynamic visual acuity in the case of the complete gain recovery as well as in the case of persisting impairment of the gain and the development of sufficient 'covert' saccade.

[Cervical vertigo from the perspective of an otorhinolaryngologist].

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.
