Hearing Outcomes of Stapedotomy In Patients With Otosclerosis

Objective: This study was focused on the assessment of patient’s improvement in hearing, as measured by pure tone audiometry after stapedotomy for primary otosclerosis. Materials and Methods: prospective clinical performed a total 156 patients diagnosed with Primary Otosclerosis, who underwent Stapedotomy at Department ENT & Head-Neck Surgery, Combined Military Hospital Dhaka between January 2013 to 2019. All were evaluated per candidacy criteria selected surgery during period followed up 12 months Otology clinic. Pre Post-operative audiometric evaluation done using conventional standard calibrations. 03 month, 06 months. The bone-conduction air conduction thresholds Air-Bone gap (ABG), documented analyzed 0.5 KHz, 1 2 KHz 4 frequencies respectively. subjective outcomes hearing also recorded patient satisfaction questionnaire assess quality stapedotomy. Results: Overall, frequency specific pre-operative mean averaged Air Conduction 63.3dB 500Hz, 57.5dB 55.1dB 45.7dB KHz. post-operative thresolds 34.6 dB 28.9 1Kz, 30.5dB 2Kz 33.3dB 4Kz.The average post operative Bone Gap (ABG) closure achieved 28.7dB 27.6 1KHz, 24.6 2KHz 12.4 4KHz time completion 01 year. A successful AB less than 10dB speech 83.97% cases. unchanged postoperatively all cases except 03, showing that no significant sensori-neural impairment had occured due procedure. 04 developed post-op severe vertigo which self-limiting six weeks. transient facial weakness subsided over Patients included our audiological responded satisfactorily formulated their Conclusions: Our case confirms is safe procedure providing long-term shows meticulous selection will result highly outcomes.
