[Speech perception and the state of sound perception thresholds in patients with cochlear implants]. / Vospriyatie rechi i sostoyanie porogov zvukovospriyatiya u patsientov s kokhlearnymi implantatami.

OBJECTIVE: To assess the state of the thresholds of sound perception at speech frequencies in users of cochlear implantation (CI) systems with developed speech skills. MATERIAL AND METHODS: The study involved 30 patients - users of CI systems, of whom 17 girls, 13 boys aged 6 to 14 years. All patients underwent speech audiometry in a free sound field twice (at the beginning of the study and after adjusting the settings of the speech processor). The ASSR (auditory steady-state responses) thresholds were recorded as the second stage to assess the perception of non-speech stimuli after adjusting the settings of the speech processor. RESULTS: Correlation analysis was carried out between the percentage of speech intelligibility and the average ASSR thresholds. There was no statistically significant relationship between lowering the ASSR thresholds and speech intelligibility. The absence of a relationship between speech intelligibility and user satisfaction with the speech processor settings was revealed. Improving the intelligibility of the user's speech by the CI system did not affect the improvement on the response to the addressed speech.

[Myoclonus of the middle ear]. / Mioklonus myshts srednego ukha.

The objective of the present study was to overview the foreign literature concerning middle ear myoclonus (MEM) known to be the most common cause of the manifestations of objective tinnitus. The authors reports two typical clinical cases of myoclonus of the middle ear. The present article is aimed at the enhancement of the awareness of the otorhinolaryngologists, audiologists, and neurologists of the condition of interest as a way to promote the further progress in its treatment.

[The psychogenic hearing disorders in the children and adolescents]. / Psikhogennoe narushenie slukha u detei i podrostkov.

The psychogenic loss of hearing is characterized by its impairment in the absence of anatomically and physiologically significant changes. These disorders are poorly represented in the scientific literature in comparison with the organic lesions. They are especially frequently overlooked in the children and adolescents. The objective of the present review was to analyze the literature publications concerning this problem and to report two clinical observations of the pathology in question. It is concluded that the clinically significant discrepancy between the audiological symptoms and the results obtained by the objective methods for hearing evaluation should be interpreted with great caution and raise the suspicion of the disease. The diagnosis and the identification of the involved psychogenic factors are of utmost importance for the success of the treatment.

[Congenital choanal atresia]. / K voprosu o vrozhdennoi atrezii khoan.

In 1990-1995 the authors treated 40 children (age 1 month to 12 years) with congenital choanal atresia (CA). Bilateral CA occurred in 4, unilateral in 36 children. Complete and incomplete CA were diagnosed in 37 and 3 patients, respectively. Other congenital anomalies were registered in 7 children. Fibroendoscopy and computed tomography proved best in providing diagnostic information, while endonasal method with finger control was most available. The optimal time of protector carrying was at least 2.5 months.
