Otosclerosis is alteration in bony metabolism that is exclusive to the otic capsule and stapes footpalate. The process of resorption and redeposition of bone result in fixation of the ossicular chain and conductive hearing loss. Otosclerosis occurs in all age groups, but the usual clinical presentation varies from second to fifth decade of life. Tinnitus is defined as a conscious awareness of a sound in the absence of an external auditory stimulus and is usually one of the earliest symptoms of otosclerosis; moreover 65 % of all patients with otosclerosis experienced clinically significant, chronic tinnitus before stapes surgery. The objective of this study was to find the effect of stapedotomy on tinnitus for otosclerosis patient. Forty five otosclerosis patient whom thirty five with preoperative tinnitus were enrolled to the study. Pure tone average Air-Bone Gap values was measured few mounts before and few mounts after stapedotomy. Also, the patient was asked questions from the specific question mark with numerical scale (NRS) for intensity of tinnitus adapted to otosclerosis patient. The results of this study showed that 42.85 % of the patient that enrolled in study experienced complete tinnitus reduction, 25.71 % of the patient experienced sever tinnitus reduction and 31.43 % of the patient was not experienced any tinnitus reduction. In conclusion, this study shows that stapedotomy can be used to achieve full or partial resolution of tinnitus in majority of patients with otosclerosis.
