Özet
Objective: To analyse postoperative audiological findings in fenestral otosclerosis patients treated with stapedotomy, focal location-extensiveness findings on temporal high-resolution computed tomography (HRCT), and intraoperative macroscopic stapes footplate findings. Moreover, preoperative audiological findings were compared with HRCT and intraoperative macroscopic findings. Study Design: An observational study. Place and Duration of Study: Department of Otorhinolaryngology, University of Health Sciences, Ankara Numune Training and Research Hospital, Turkey from January 2015 to January 2018. Methodology: Patients were classified according to the temporal bone HRCT findings into three groups based on otosclerotic focus location and extensiveness. Macroscopic classification was based on the intraoperative findings of blue and white footplate. Patients with obliterative otosclerosis were not included in the study. Preoperative and postoperative audiological findings as well as surgical success were investigated. Findings were compared with HRCT and macroscopic classification groups. Results: Postoperative air bone gap (ABG) increased as HRCT class increased from 0 to 3, meaning a more extensive otosclerotic focus (p=0.002). The comparison of the audiological outcomes, in accordance with the intraoperative findings, revealed that the postoperative air conduction pure-tone averages (AC PTA), ABG and ABG difference were higher in the white footplate group, with statistically significant differences compared to blue footplate group (p = 0.039, p = 0.001 and p=0.029, respectively). Conclusion: Postoperative audiological findings were found to be correlated with intraoperative and HRCT findings. A white footplate seen at surgery or a more extensive otosclerotic focus on temporal HRCT indicates a suboptimal audiological outcome. HRCT findings should be taken into account when planning the surgery.
