Analysis of Causative Disorders and Hearing Improvement in 100 Consecutive Stapes Surgeries

Background and Objectives Stapes surgery has been widely used to improve the conductive hearing loss caused by stapedial fixation. The purpose of this study is evaluate causes fixation using audiological results 100 stapes surgeries. Subjects Method We reviewed medical records consecutive surgeries between June 2011 December 2022. A total ears from 86 patients were included patient age ranged 6 80 years. Hearing improvements pure-tone thresholds defined as successful when air-bone gap (ABG) was reduced 20 dB or less, excellent ABG within 10 dB. Results causative diseases otosclerosis (n=74, 74%), ossicular anomaly (n=19, 19%) chronic otitis media (n=7, 7%). Overall, pre-operative bone-conduction thresholds/air-conduction (BC/AC) 32±14/58±18 HL 26±11 while postoperative BC/AC 29±15/36±18 7±8 in 77% 93%. 82.4% 97.3% otosclerosis, 78.9% 89.5% anomaly, 14.3% 57.2% for media. significantly improved less revision cases than primary (p=0.006). Conclusion an effective method various types There a difference degree improvement according disorders. Key words: Conductive ㆍ Otitis Otosclerosis
