Along with the respiratory, cardiovascular, gastrointestinal, rheumatological, and neurological manifestations of the new coronavirus infection (COVID-19), the effects of this virus on the ENT organs is undeniable, as the main portal of entry of any respiratory infection. It has been proven that symptoms such as hypo- and anosmia are associated with one of the ways of the virus penetration – transnasal, through the olfactory nerves into the central nervous system. Otorhinolaryngological complaints of patients are not limited only to deterioration or loss of smell, many note the appearance of dizziness, tinnitus, worsening of the course of chronic sensorineural hearing loss, and in some cases – sudden hearing loss, which may indicate damage to the auditory and vestibular analyzer by a viral agent. The mechanisms of development of the corresponding complications at the moment are still unclear. The presented article is a review of the literature data of foreign and domestic sources, which examines the central and peripheral neurological complications, the pathways and molecular features of the penetration of the virus, as well as clinical cases of hearing impairment and the appearance of tinnitus against the background of new coronavirus infection. At the moment, information on the direct effect of the SARS-CoV-2 virus on the auditory and vestibular analyzer is insufficient and scattered, which requires further observation with subsequent detailed analysis of the results.
Currently, one of the most pressing concerns of labor psychology and healthcare is emotional burnout in healthcare professionals. During the COVID- 19 pandemic this condition has become very significant due to it takes a lot of physical, phychoemotional and ethical commitment of medical personnel. Emotional burnout is a syndrome that derives from chronic stress and leads to the depletion of personal, emotional, and energy resources of a person in the professional life. It is an dynamic sequential process and relevant to stress stages (the alarm stage, the resistance stage and the exhaustion stage). There are many various factors inducing the burnout syndrome: social, political, economic, bureaucratic, etc. In the process of studying this phenomenon, different models of emotional burnout were proposed. The most famous model is the three-part model of burnout by С. Maslach, which includes emotional exhaustion, depersonalization and a decrease in personal achievements. In Russia V. V. Boyko has been studying the burout phenomenon. There are three main stages of emotional burnout (alarm, resistance and exhaustion), which have a close connection to stress stages; each stage has a specific combination of symptoms. According to a number of authors, burnout syndrome is closely related to empathy, therefore, it is necessary to study the relationship between the level of empathy and the degree of emotional burnout in healthcare professionals for planning further psychological support for the prevention of this syndrome.
Sudden sensorineural hearing loss is still a difficult task for many specialists, not only due to the fact that in most cases the cause of the disease cannot be identified but also due to the lack of effective methods of treatment and rehabilitation. Objective. To assess the etiology, prevalence, structure, and gender aspects of sudden single-sided sensorineural hearing loss. Material and methods. A retrospective review of outpatient records to identify patients with single-sided sudden sensorineural hearing loss for subsequent detailed analysis of the data obtained. The main inclusion criteria were age over 18 years, single-sided hearing loss with perception thresholds corresponding to the IV degree of hearing loss/deafness (according to the unified WHO classification, 1997), sensorineural type of hearing loss, and sudden onset of the disease. Results. A study group was formed consisting of 82 patients with sudden single-sided sensorineural hearing loss. An analysis was made of the main etiological factors, prevalence, structure, and gender aspects of this pathological condition. Conclusions. It was found that sudden unilateral SNT is diagnosed on average in 3.2% of cases, is predominantly idiopathic in nature, manifests itself in the 4th–5th decade of life, has no gender differences, but is characterized by a more frequent lesion of the left ear.
At the end of 2019, an outbreak of a new coronavirus infection began in China, Wuhan, which is the first pandemic of the 21st century. The International Committee on Taxonomy of Viruses has classified the causative agent of the new disease as SARS-CoV-2, and on February 11, 2020, the World Health Organization (WHO) announced the official name of the infection – COVID-19. According to statistics for August 2021, the number of people infected with SARS-CoV-2 in the world is 216 million, and the number of deaths is 4.5 million. COVID-19 can be asymptomatic or manifest with various clinical manifestations, including neurological and otorhinolaryngological. The article describes 3 clinical cases of unilateral sudden hearing impairment in patients with confirmed COVID-19. The diagnosis of unilateral sensorineural hearing loss was established using acumetry, tone threshold audiometry, acoustic impedance measurement, and recording of otoacoustic emissions. In most cases, COVID-19 is characterized by a certain clinical picture, however, with an asymptomatic and mild course, an atypical manifestation of the disease with the development of sudden sensorineural hearing loss is possible.
Profound hearing loss makes it difficult for a person to fully integrate into society. Cochlear implantation is rightfully considered a universal and an effective method of rehabilitation of patients with severe and profound hearing loss. The advantages of binaural hearing are well known; the advantages of bilateral cochlear implantation over monolateral implantation are undeniable, due to the restoration of all binaural hearing effects. At the moment, the relevance of simultaneous cochlear implantation, especially among children, and its benefits compared with sequential implantation are being discussed. It is known that there are special groups of patients among patients with hearing loss; they are either unrehabilitated at all or rehabilitation measures for which are ineffective. Special patient groups include patients with unilateral acquired or congenital deafness, asymmetric and residual hearing loss. Patients in these groups often complain of poor speech intelligibility, especially against a background of noise, inability to localize the source of sound, one-sided or two-sided tinnitus, and, as a result, a deterioration in the quality of life. All abovementioned makes us think about the need to revise the indications for cochlear implantation and study this issue in detail.
