Cochlear implantation after postmeningitic deafness has favorable outcomes especially in long term. Although this type of inner ear pathology may require special considerations during surgery, it is a relatively safe procedure.

Background and Objectives: This study aimed to evaluate the audiologic results after cochlear implantation (CI) in older patients and the degree of improvement in their quality of life (QoL). Subjects and Methods: Patients over 65 years old who underwent CI at implant center in Bozyaka Training and Research Hospital were included in this study (n=54; 34 males and 20 females). The control group was patient over 65 years old with normal hearing (n=54; 34 males and 20 females). We administered three questionnaires [World Health Organization Quality of Life-BREF (WHOQOL-BREF), World Health Organization Quality of Life-OLD (WHOQOL-OLD)], and Geriatric Depression Scale (GDS) to evaluate the QoL, CIrelated effects on activities of daily life, and social activities in all the subjects. Moreover, correlations between speech recognition and the QoL scores were evaluated. The duration of implant use and comorbidities were also examined as potential factors affecting QoL. Results: The patients had remarkable improvements (the mean score of postoperative speech perception 75.7%) in speech perception after CI. The scores for the WHOQOL-OLD and WHOQOL-BREF questionnaire responses were similar in both the study and control groups, except those for a two subdomains (social relations and social participation). The patients with longer-term CI had higher scores than those with short-term CI use. In general, the changes in GDS scores were not significant (p<0.05). Conclusions: The treatment of hearing loss with CI conferred significant improvement in patient's QoL (p<0.01). The evaluation of QoL can provide multidimensional insights into a geriatric patient's progress and, therefore, should be considered by audiologists.

Background/aim: To emphasize the role of cochlear implantation (CI) in the auditory rehabilitation of patients with otosclerosis (OS) and share our surgical experiences on this rare group of patients. Materials and methods: Retrospective analysis of the patients who have a diagnosis of otosclerosis and implanted between January 1998-May 2019 was performed. Preoperative and postoperative clinical, radiological, audiological and surgical findings are presented. Results: Among 2195 patients who have been implanted in our institution, 12 (0.54%) met the diagnostic criteria of OS according to their preoperative (clinical, radiological, audiological) and peroperative (surgical) findings. Electrode insertion was performed via "round window membrane and cochleostomy" in 8 and 4 patients, respectively. No major complications occured. All patients showed satisfactory performances by means of audiometric scores postoperatively. Nonauditory stimulation (NAS) which manifested as "facial twitching" was a challenging problem in one patient during the surgery and subsided after the operation. Conclusion: Our experience on CI in patients with OS revealed that the implantation was a relatively safe procedure and had satisfactory impact on audiological performances.

Objective To examine the complication rate in adult patients during and after cochlear implantation. Methods A retrospective chart review was conducted of patients who had undergone cochlear implantation at a tertiary referral centre between 2009 and 2018. All complications and their treatments were categorised as either minor or major, as well as intra- or post-operative. Results The records of 392 patients with 395 implants were reviewed. The mean follow-up period was 89 ± 65.5 months (range, 6–408 months). The mean age of patients was 46 ± 15.2 years (range, 19–84 years). Sixty-two patients (16 per cent) had minor complications and 31 (8 per cent) had major complications. Conclusion Although cochlear implantation has the potential for significant intra- and post-operative complications, the actual complication rate is relatively low, and it can therefore be considered a safe procedure.
