Bilateral Hearing Loss Following Unilateral Stapes Surgery

Otosclerosis is a common cause of conductive hearing loss. It is surgically treated with stapedectomy or stapedotomy. Sensory-neural hearing loss is an uncommon but known complication of this surgery. A 25-year-old Iranian female with bilateral otosclerosis underwent right stapedotomy and developed bilateral sensorineural hearing loss a few days after the surgery, which recovered with appropriate treatment. The possible causes and their clinical courses are discussed in this study. Sensorineural hearing loss after stapedotomy has many different etiologies. Generally, the causes which are not directly related to the surgery should also be considered.
