    Objective: Cochlear implantation (CI) is an electronic device that converts mechanical sound energy into electrical signals and transmits it directly to the cochlea, allowing sound perception. These implants were applied to patients with severe sensorineural hearing loss who did not or had little benefit from the conventional hearing devices. This study aimed to investigate behavioral problems, find related factors, and determine the relationship between behavioral problems and parents' attitudes in children with CI. Methods: The investigation involved the participation of fifty individuals, comprising 26 males and 24 females, between 4 and 18 years, with a mean age average of 4 +/- 1.56 without any neurological and developmental problems. Inclusion criteria required a minimum of one year post-CI follow-up and a corresponding minimum duration of one year utilizing CI. Achenbach's Child Behavior Checklist (CBCL) assessed behavioral aspects. Categories of Auditory Performance II (CAP) and The Speech Intelligibility Rating Scale (SIR) scales were employed to evaluate auditory performance and speech intelligibility. Parental attitudes were gauged using the Parent Attitude Research Instrument (PARI). The selection of fifty patients was accomplished through a simple random sampling technique, with no considerations for gender or social status differences during case selection. Results: The patients who applied the CI bilaterally were more successful than the one-sided. The success rate of patients who had comorbidities was statistically significant. Aggressive behavior was less in patients operated on before age 4. There are no differences between the relations of friend circle, art, and sports-interested patients. For CAP II and SIR, there is a moderate statistical significance between the duration of use and CAP. CAP scores were analyzed high in patients who used the device for over six years. There is a moderate statistical significance between CAP and SIR correlation. Our research found a statistically significant decrease in all behavioral scales when comparing preoperative and postoperative scores. Although there was only a non-significant decrease in the delinquent behaviors score, a decrease was still observed. There were significant changes in males but no significant difference based on gender in our study. Conclusion: The findings imply that implementing cochlear implants in younger children might yield even greater advantages. Our research adds to the expanding collection of evidence endorsing CI as a viable therapeutic choice for youngsters with hearing impairments, underscoring the necessity for continued investigations within this domain.

    Surgical Methods and Auditory Outcomes of Cochlear Implantation in Cochlear Ossification
    (2022) Tokat, Taskin; Catli, Tolgahan; Bozkurt, Ergul Basaran; Olgun, Levent; 35193846
    BACKGROUND: The aim of this study was to evaluate the surgical and auditory outcomes of cochlear implantation in patients with cochlear ossification. METHODS: This study comprised 54 patients with cochlear ossification who underwent cochlear implantation in the cochlear implant center of a tertiary care hospital between January 1998 and May 2019. Clinical data were evaluated including surgical findings and audiological performances. The auditory outcomes of the implanted patients were assessed through the Categories of Auditory Performance-II test and Speech Intelligibility Rating test, respectively. The outcomes of patients with cochlear ossification were compared with those of 54 patients selected for the control group who underwent implantation with no cochlear ossification. RESULTS: Auditory outcomes were comparable between the study group and the control group. The control group obtained significantly higher scores than those of the study group when compared using the Categories of Auditory Performance-II test and Speech Intelligibility Rating test batteries. Patients with meningitis produced poorer outcomes within the group comparisons of the study group. None of the patients experienced surgical complications. The extent of ossification was analyzed in terms of its effectiveness on audiological performance. Patients with complete ossification had significantly lower Categories of Auditory Performance-II and Speech Intelligibility Rating test scores. CONCLUSION: Cochlear implantation is a safe and beneficial procedure, even in patients with cochlear ossification. The ossified cochlea may require varied drill techniques beyond traditional implantation surgery for the insertion of the electrode array. It is, however, still difficult to predict audiological outcomes in patients with cochlear ossification.

    Surgical considerations and audiological results of cochlear implantation in patient with otosclerosis
    (2020) Catli, Tolgahan; Tokat, Taskin; Bozkurt, Ergul Basaran; Adibelli, Zehra Hilal; Ergun, Ugurtan; Altas, Enver; Olgun, Levent; 32283908
    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.
