Objective - to investigate the association between patient age, duration and etiology of hearing loss on buzzing and ringing in ears dynamics in patients after cochlear implantation. Actuality. Most of the studies confirm that cochlear implant use results in significant buzzing and ringing in ears decrease. Still there are cases of tinnitus development (up to 3%) or increase (from 1 to 9%) after cochlear implantation. Most of these differences are explained with the complex mechanism of tinnitus development that should be taken into account in cochlear implantation clinical outcome prognosis. The aim of the study is to present the main results of factors influencing the tinnitus severity after cochlear implantation analysis. Materials and methods. From 2013 to 2015 cochlear implantation was performed in 385 patients with stage 4 bilateral sensorineural hearing loss who presented with buzzing and ringing in ears. The severity of hearing loss was evaluated with visual analogue scale questionnaires. Among factors presumed to affect the changes in tinnitus intensity patients’ sex and age, hearing loss (deafness) duration and tinnitus severity and etiology were evaluated. Results. According to the study results, positive prognosis markers of cochlear implantation in patients with tinnitus in severe hearing loss rehabilitation include severe hearing loss (stage 4) and deafness duration of less than 2 years. Conclusion. The study provides evidence of new indication for effective cochlear implantation use in patients with unilateral deafness and severe tinnitus.

Aim. This study aims to compare the major role is played by the following objective fitting methods for such CI-users: registration of electrically evoked compound action potentials (eCAP), electrically evoked stapedial reflexes (eSRT), electrically evoked auditory brain stem responses (eABR). Materials and methods. This study includes 100 patients after CI-users, aged between from 12 and to 55 years old. Participants primarily patients were initially fitted in accordance with subjective maximum comfortable loudness (MCL) levels. Results. Results show that the correlation between in eSRT and MCL levels was accounts to 0.87. Correlation between eCAP and MCL was accounts to 0.52. To evaluate the MCL thresholds with eABR, we used 3-5 supraliminal stimuli were applied on 2, 5, and 10 electrodes, respectively. The correlation between the subjective MCL levels and the calculated MCL levels was 0.86. Conclusion. As can be seen from the above, there has been a with the significant increase of fitting objective methods accuracy in the audiological performance of CI-users patients after following the application of cochlear implantation notably improve objective fitting methods.

The article considers endolaryngeal methods of surgical treatment of hyperplastic processes in the larynx using modern technologies, both for diagnosis and for surgical treatment. Author's methods of endolaryngeal interventions with the use of CO2-laser are presented. The results are analyzed in the postoperative and long-term periods.

The article focuses on a challenging issue of occupational pathology, pulmonology and oncology - occupational malignant tumors of the lungs. The leading factors of cancerogenesis and industrial processes that result in occupational malignant lung tumors development are discussed.

The article presents a case report of successful surgical treatment of giant frontoethmoidal osteoma. We didn't use the conversion in the external approach. The frontal sinus surgery was performed by endoscopic endonasal surgery under the control of image guidance. Circumoral oedema developed in the early postoperative period, which successfully stopped with the use of antibacterial, anti-inflammatory therapy.
