    Comparison eCAP and behaviour thresholds in post lingual medel cochlear implant users
    (İnönü Üniversitesi Tıp Fakültesi, 2020) Saraç, Elif Tuğba; Deniz, Hüseyin; Okuyucu, Şemsettin
    Aim: Our purpose with this study is to determine the most effective and suitable cochlear implant programming method for CI users’ implants to experience quality hearing and for the users to achieve efficiency from their implants. Materials and Methods:Twenty-five cochlear implant users with post lingual progressive hearing loss were included in the study. Twelve electrodes’ ART (auditory nerve response telemetry) thresholds were determined and were statistically analyzed to be evaluated in the study. For 12 electrodes whose AutoART threshold was determined, the MCLs (most comfortable loudness) were determined behaviorally. Results: No correlations were found between the 12 electrodes and AutoART. It was seen that there was a correlation between the pure tone average obtained from 500-1000-2000 and 4000Hz and the speech reception threshold. Conclusion: The use of two test batteries together to determine thresholds can be helpful in the programming of the speech processor. The more audiologists work with cochlear implant patients and do programming, the more they accumulate data and gain occupational experience. With the occupational experience acquired in this manner, more accurate programming can be done.

    Effects of tinnitus masking therapy in tinnitus patients with and without hearing loss
    (Turgut Özal Medical Center, 2018) Saraç, Elif Tuğba; Arlı, Ali;
    Aim: The aim of the study is to determine the effects of tinnitus masking therapy on patients with and without hearing loss. Material and Methods: This study includes a total 34 of patients with tinnitus, between 27 and 70 years of age, 16 of whom with and 18 of whom without hearing loss. The patients with and above 25 dB were added to the group without hearing loss and those below 25 dB to the group with hearing loss. The patients had one session each day. Previously determined and appropriate for tinnitus mapping, sound was made to be listened through TDH 39-P model earphones for 30 minutes during the therapy. Before and after the ten-sessions therapies, the effects of masking therapy on the patients were assessed through Tinnitus Handicap Inventory. Result: Tinnitus Handicap Inventory scores were found significantly low in patients with and without hearing loss after tinnitus masking therapy (p =0.026 and p = 0.023). And, in comparison made between the groups, Tinnitus Handicap Inventory scores before and after tinnitus masking therapy were found to be similar(p<0.05). Conclusion: Both groups benefited from masking therapy at similar levels. Tinnitus masking therapy is effective on both patients with and without hearing loss. The success of masking therapy is related to proper patient selection. Regular follow-up is essential.

    Evaluation of hearing loss in patients with OSAS and the relationship between S100B and NSE
    (PLEKSUS BİLİŞİM TEKN. DANIŞ. TEMS. YAY. ORG. A.Ş., 2020) Arlı, Cengiz; Saraç, Elif Tuğba; Özcan, Oğuzhan; Babayiğit, Cenk; Dikmen, Nursel; Doğru, Sibel; Okuyucu, Emine Esra
    Objective: The aim of the current study was to determine the relationship between serum S100B levels, NSE levels and hearing function in patients with OSAS. Material and Methods: Thirty-five subjects and 30 controls were included in the study. The study group included 35 patients with moderate and severe apnoea (AHI > 15) who were diagnosed by polysomnography (PSG). Control subjects were selected with ESS (Epworth Sleepiness Scale). Serum S100B and NSE levels in the study and control groups were analyzed by ELISA (enzyme-linked immunosorbent assay) and high-frequency audiometry was done for all subjects. Results: Mean S100B levels and NSE levels of the OSAS group were significantly higher than that of the controls (p = 0.039; p = 0.002, respectively). The hearing thresholds between 125-1,000 Hz and between 4,000-12,000 Hz in the study group were found to be significantly higher than the control group. Conclusion: We suggest that hearing function should be evaluated in OSAS patients and a professional consultation should be sought for OSAS treatment. In addition, serum S100B and NSE measurements may be valued as biochemical indicators in determining hearing loss risk caused by OSAS.
