Stapedectomy: Understanding the Procedure and Treatment for Hearing Loss

Stapedectomy is a microsurgical procedure to treat otosclerosis, a condition where the stapes (smallest middle ear bone) becomes fixed, preventing sound transmission to the inner ear.

Procedure

1. Remove the immobilized stapes.
2. Replace with a tiny prosthesis (piston) made of Teflon, stainless steel, ceramic, or other biocompatible material.
3. The prosthesis conducts vibrations from the incus to the oval window, restoring hearing.

Indications

• Significant conductive hearing loss from otosclerosis.
• Failed or unsuitable hearing aid trial.
• Patient preference for surgical correction.

Outcomes

High success rate; typically outpatient under local anesthesia. Most patients experience substantial hearing improvement.
