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.

Objective. To analyze the incidence of lymphoid structures of the pharynx among the adult population during the period from January 2021 to August 2022 in three nosological forms: chronic decompensated tonsillitis (CDT), hypertrophy of pharyngeal tonsils (HPT), hypertrophy of lingual tonsillitis (HLT). To determine the relationship of the above pathology between the age and sex of patients at the present stage. To evaluate the role of mycobiota in the structure of pharyngeal morbidity.Materials and methods. The object of the study was 96 patients with chronic pathology of the lymphoid structures of the pharynx aged from 17 to 70 years, who were on inpatient treatment at the Gomel Regional Clinical Hospital (GRCH) during the period from January 2021 to August 2022. All patients underwent surgical intervention followed by an assessment of the pathohistological conclusions of postoperative samples of pharyngeal lymphatic formations. The patients were divided into 3 nosological study groups: CDT; HPT; HLT. Statistical data processing was performed using software: MS Excel and the programming language for statistical data analysis R (version 4.2.1), packages tidyverse (version 1.3.1), rstatix (version 0.7.0), ggstatsplot (version 0.9.5).Results. The study revealed the most common nosological groups among patients with pathology of the pharyngeal lymphatic ring of Pirogov-Waldeyer: CDT (44%) and HPT (38%). A significant difference was revealed between the incidence rates of pathology of the Pirogov-Waldeyer pharyngeal lymphatic ring in the study age groups from 17 to 25 years (p=0.0008); from 26 to 35 years (p=0.0021); 56 years and older (p=0.008). The median age of patients in the study group was 35 years (LQ 24.0; UQ 48.5), whereas in some nosological forms: CDT – 30 years (LQ 23.0; UQ 41.0), namely 28 years among women and 36 years among men; HРT – 32.5 years (LQ 24.0; UQ 43.25), namely 34.5 years among women and 31.5 years among men; HLT – 57 years (LQ 49.0; UQ 63.0), and it is 56.5 years among women and 57 years among men. Morphological examination revealed only 2 (2%) cases of mycotic lesions of the removed lymphoid masses.Conclusion. The relationship between the pathology of lymphoid structures of the pharynx in three nosological forms (CDT, HPT, HLT) and the age of patients was revealed. The role of mycobiota in the overall study group in the structure of pharyngeal morbidity at the present stage was evaluated.
