Surgery for otosclerosis: stapedectomy and recovery
Otosclerosis is a common cause of adult‑onset hearing loss. It stiffens the stapes footplate and creates a conductive block in the middle ear. The cause is likely a mix of genetics and environment. When hearing loss limits everyday life, or when hearing aids no longer give enough benefit, surgery for otosclerosis is a strong option.
Diagnosis: how we confirm otosclerosis
Most people notice gradual hearing loss and often tinnitus, while the eardrum looks normal. An audiogram for otosclerosis usually shows a conductive pattern, sometimes with a 2 kHz carhart notch. Tympanometry is commonly type a or as, and acoustic reflexes are often absent. A ct scan is reserved for atypical cases, mixed hearing loss, or surgical planning.
Stapedectomy surgery overview
Stapedectomy surgery is the reference procedure among modern hearing loss operations for stapes fixation. In experienced hands it reliably restores middle‑ear mechanics.
What happens in theatre
The operation is performed under general anaesthesia with a transcanal microscopic or endoscopic approach. The tympanic membrane is elevated and a small atticotomy is created to visualise the ossicles. The incudostapedial joint is gently disarticulated.
Laser‑assisted dissection
Using a ktp laser, the stapedius tendon and the stapes crura are divided. The anterior crus is fractured and the suprastructure is removed with precision.
Footplate fenestration and prosthesis
A small, precise opening is made in the footplate. An mri‑compatible piston prosthesis reconnects the incus to the vestibule. This is the key step of the otosclerosis operation.
Closure and dressing
The tympanic flap is repositioned and the ear canal is packed for about ten days to support healing and reduce infection risk.
Alternatives if you are not a candidate
Many patients do well with hearing aids. A modern otosclerosis hearing aid can provide meaningful improvement and remains an option even after surgery if needed.
Recovery: what to expect
Typical otosclerosis surgery recovery time is five to seven days of taking it easy. Light work is usually possible after a week. Avoid water in the ear, heavy lifting and pressure changes until your surgeon advises otherwise. Maximal hearing improvement is expected by three to four months as the middle ear settles.
Results and success rate
Across large series of primary stapedectomies, the otosclerosis surgery success rate exceeds 90% for closing the air–bone gap to 10 db or better. Fewer than 10% may need a revision later in life. These outcomes make stapedectomy a definitive option among surgery for deafness caused by stapes fixation.
Risks you should know about
Short‑lived dizziness is common in the first days. Sensorineural hearing loss occurs in about one to two percent of cases. A perilymph fistula is rare but can require further treatment. Your surgeon will discuss individual risk and how it is minimised.
Follow‑up and long‑term care
Close follow‑up with repeat audiogram for otosclerosis checks progress and confirms stability. With proper aftercare, results are durable for many years.
Choosing the right team
Outcomes improve with experience. Look for stapedectomy surgeons who perform this operation regularly and can share their personal results, prosthesis choices and revision rates.
Frequently asked questions
How to diagnose otosclerosis+
Diagnosis starts with a focused history and ear examination. People typically report slowly progressive hearing loss and sometimes tinnitus, while the eardrum looks normal. Tuning fork tests point to a conductive deficit. The key test is the pure‑tone audiogram for otosclerosis, which often shows a carhart notch around 2 khz with preserved speech discrimination. Tympanometry is usually normal or slightly stiff, and acoustic reflexes are often absent. A ct scan is used selectively for atypical patterns, mixed loss or pre‑revision planning.
Otosclerosis in ear symptoms+
The most common symptom is gradual conductive hearing loss, which can start in one ear and later involve both. Many people notice tinnitus and a sense of aural fullness despite no infection. Some feel they hear relatively better in noisy environments, a phenomenon called paracusis willisii. True spinning vertigo is uncommon, but brief imbalance can occur. Symptoms may progress during pregnancy in some individuals.
Otosclerosis hearing aid (when to choose it)+
A hearing aid is a good choice if you prefer non‑surgical management, if medical conditions make anaesthesia unwise, or when the hearing loss is mild to moderate and amplification restores clarity. It is also useful while staging surgery between ears or when there is a significant inner‑ear component that could limit surgical gain. Hearing aids do not stop the disease, and you can still consider surgery later if appropriate.
Otosclerosis prognosis (long‑term)+
Otosclerosis usually progresses slowly and often becomes bilateral over time, but total deafness is rare. Stapedectomy provides durable improvement for many years, though a small minority may need revision due to refixation or prosthesis issues. A modest sensorineural component can emerge with age; if that happens, hearing aids remain effective. Tinnitus often lessens after successful surgery or with amplification.
Otosclerosis eardrum (is the eardrum affected?)+
The eardrum is typically normal in otosclerosis. The disease targets the stapes and the bone around it, not the tympanic membrane. Occasionally a reddish hue behind the eardrum, called the schwartze sign, is seen, but it does not mean the eardrum itself is diseased.
