[Evaluation of the cochlear implantation users rehabilitation results using psychoacoustic methods].

Unlabelled: Currently, the number of patients with bilateral sensorineural deafness treated with cochlear implantation (CI) is increasing in the Russian Federation. In this regard, methods of assessing the auditory rehabilitation of this category of patients become more relevant.

Objective: To investigate the correlation of the speech intelligibility in quiet with frequency resolving power (FRP) of hearing using a ripple-spectrum phase reversion test (RSPRT) in CI users.

Clinical validation of the Russian Matrix test - effect of hearing loss, age, and noise level.

Objective: To validate the Russian matrix sentence test (RUMatrix) for the assessment of speech recognition in quiet and in noise in clinical praxis. The effect of hearing impairment, age, and masking-noise level on speech recognition was examined.

Design: All participants underwent pure tone audiometry, a monosyllabic speech test in quiet, and speech recognition measurements with RUMatrix in quiet (SRT) and in noise (SRT).

[Application of the matrix sentence test Russian version in children].

Unlabelled: The Russian version of the matrix sentence test (RUMatrix test) has been shown to be suitable for accurate assessment of speech intelligibility in adults.

Aim: To approve the RUMatrix for measurements in children and to evaluate its simplified version (Simplified RUMatrix).

Material And Methods: 20 normal-hearing adults and 81 normal-hearing children aged from 5 to 10 years were involved into the study.

[The application of the screening questionnaires for the diagnostics of the central auditory processing disorders in the pediatric practice].

Identification and diagnostics of auditory processing disorders (APD) in the children continues to be a challenge. Screening tools help to decide the need for evaluation. However, none of them are used routinely in Russia, nor are there thus far auditory checklist questionnaires in the Russian language.

[Application of the mathematical model for prognosis in the rehabilitation of children after cochlear implantation].

Unlabelled: Despite the variety of etiological factors, cochlear implantation (CI) remains the only effective method for the rehabilitation of the patients presenting with total deafness. The aim of this study was the enhancement of the efficiency of selection of the candidates for CI, the improvement of the quality of rehabilitation of the patients with cochlear implants, and the determination of the prognostic criteria for clinical trials.

Patients And Methods: (CI).

[The Russian-language version of the matrix test (RUMatrix) in free field in patients after cochlear implantation in the long term].

Unlabelled: The deterioration of speech intelligibility in the patients using cochlear implantation (CI) systems is especially well apparent in the noisy environment. It explains why phrasal speech tests, such as a Matrix sentence test, have become increasingly more popular in the speech audiometry during rehabilitation after CI. The Matrix test allows to estimate speech perception by the patients in a real life situation.

[The results of cochlear implantation in the patient with hereditary and non-hereditary hearing loss].

The objective of the present study was to evaluate the effectiveness of rehabilitation of the patients after cochlear implantation in the early and late periods after operation taking into consideration the etiology of congenital deafness. The comprehensive clinico-audiological examination performed during the period from 2010 to 2015 involved 246 children who had undergone cochlear implantation (CI). All children were operated at the National Research Center for Audiology and Hearing Rehabilitation in the period from 2003 to 2013.

[Reoperations after cochlear implantation].

Unlabelled: The objective of the present study: the improvement of the quality and effectiveness of the surgical stage of cochlear implantation on the basis of the comprehensive analysis of performed reoperations.

Patients: 84 patients of the 2413 ones who had undergone cochlear implantation were re-examined by revision surgery within various periods after the first intervention.

Main Results: In certain patients, the correction of the intracochlear electrode array position was performed and in 72 cases the replacement of the implant was done.
