What is Mastoidectomy?
Mastoidectomy is a surgical procedure to remove diseased mastoid air cells within the mastoid bone, located behind the ear. These cells can become infected or develop cholesteatoma, necessitating the operation.
Cortical Mastoidectomy Overview
Cortical mastoidectomy, the most common type, involves creating an opening in the mastoid bone to drain an infection. It's often the first step in treating chronic otitis media.
Surgical Technique Steps
The surgery starts with a postauricular incision, followed by mastoid cortex removal. Air cells are meticulously exposed and eradicated, with care to preserve the facial nerve and hearing structures.
Indications for Surgery
Indications include chronic otitis media, cholesteatoma, mastoiditis, and complications from ear infections. It's critical for preventing intracranial complications and hearing loss.
Risks and Complications
Potential risks include facial nerve damage, hearing loss, dizziness, tinnitus, cerebrospinal fluid leak, and infection. Surgical precision is key to minimize these risks.
Postoperative Care
After surgery, patients may experience discomfort and drainage. Antibiotics and pain management are important. Follow-up visits ensure healing and detect any complications early on.
Advancements in Technique
Recent advancements include endoscopic mastoidectomy, which offers less invasive surgery with potentially faster healing times and reduced scarring compared to traditional approaches.
