Objective. To analyze the current state of diagnosis and treatment of patients with chronic hyperplastic laryngitis (CHL) for the period 2010–2021 in the Republic of Belarus on the example of patients in the Dobrush District of the Gomel Region and to identify shortcomings for the subsequent development of measures to prevent malignant diseases of the larynx. Material and research methods. The material for the study was patients of the Dobrush District of the Gomel Region (61 patients: 39 (64%) men and 22 (36%) women) with a diagnosis of chronic hyperplastic laryngitis who are registered with an otorhinolaryngologist. The median age at diagnosis was 45.6 years (18 to 76 years). In the age distribution, 2 peaks were observed: from 36 to 40 years and from 51 to 55 years – 16% (10 out of 61) of the entire group, 87% of patients were of working age. Results and discussion. Patients with precancerous diseases of the larynx, who are on regular medical check-up in the Dobrush Central District Hospital, were analyzed. Age-specific incidence rates were analyzed and differentiated by gender and place of residence. The analysis of symptoms, the time spent by patients on regular medical check-up, the frequency of visits to the otorhinolaryngologist in the order of regular medical check-up was carried out. All patients had voice changes of various nature and severity: 50 (82%) patients complained of hoarseness, 6 (10%), of hoarseness, 5 (8%) had aphonia. More than half of the patients had the following complaints: feeling of a coma or a foreign body in the throat – 90%, the presence of a cough not associated with colds – 75%, and shortness of breath on exertion – 70% of patients. The median time spent by patients on regular medical check-up was 5 years (from 0 for patients registered in 2021 to 30 years). The frequency of visiting an otorhinolaryngologist in the order of regular medical check-up was from 1 time in 2–4 months (10% of patients) up to 1 time in 5 years (3%), 44% – 1 time per year, 27 (44%) patients received outpatient treatment, 5 (8%) patients received inpatient treatment, and 29 (48%) patients received both outpatient and inpatient treatment. During inpatient treatment, 16 (47%) hospitalized patients underwent surgical treatment to remove hyperplastic areas of the mucosa, the rest received antibiotic therapy, 15 (44%) patients underwent a biopsy. Conclusion. The study revealed a number of problems in the diagnosis and treatment of CHL, the main of which is the establishment of a generalized clinical diagnosis without performing a biopsy and clarifying the form of CHL and, as a result, conducting numerous ineffective courses of conservative treatment, both on an outpatient basis and in a hospital setting. It is necessary to develop a system of measures to improve the effectiveness of treatment of patients with CHL and the prevention of malignant neoplasms of the larynx.

The authors analyzed the records of surgery for cochlear implantation (CI) of 261 patients aged 8 months through 16 years. All CI operations were performed at Republican Center for Research and Practice in Otolaryngology at the period of 2010-2017 according to our methods and using the techniques providing the minimal degree of injuries and complications. The surgical findings have been revealed in 56 (21.5 %) of 261 patients, the total number of findings is 60. The detected anatomical variants of the middle and inner ear structure were grouped according to the principle of their relationship to a certain stage of CI: the access to the middle ear cavity – 4 cases (6.66%), the access to the inner ear – 19 (31.6%), the formation of the implant receiver bed – 30 (50%). The specific features of the facial nerve position have been referred to the separate group. Each 5th patient (21.5%) had anatomical features complicating the surgery and increasing the risk of complications occurrence, in every 11th patient (8.8%) the anatomical features complicated the access to inner ear.
