Stapedectomy is the surgical procedure performed to treat otosclerosis. This procedure is typically carried out under general anesthesia. A small incision is made within the ear canal to access the middle ear, behind the eardrum. The connections and mobility of the ossicles (malleus, incus, and stapes – hammer, anvil, and stirrup) within the middle ear are carefully assessed. The definitive diagnosis of otosclerosis is confirmed by observing normal mobility in the malleus and incus, coupled with absent or severely impaired mobility of the stapes bone. Once confirmed, the stapes bone is replaced with a specialized Teflon prosthesis to restore its function, concluding the surgical intervention. Post-operatively, the patient remains under hospital observation for 1-2 days before discharge. A follow-up appointment is scheduled for one week later, during which the external ear canal is cleaned, and continued monitoring is ensured. Hearing evaluation is performed through control audiometry tests conducted at one month and three months following the surgery.
