Mastoidectomy is a surgical procedure performed to remove infected or damaged air cells from the mastoid bone, which is located behind the ear. It is most commonly required in cases of chronic ear infections or the presence of cholesteatoma, a destructive growth that can damage ear structures if left untreated.

The primary goals of mastoidectomy are to eradicate infection, prevent serious complications, and protect vital structures of the ear and surrounding areas. By removing the diseased tissue, the procedure helps stop persistent ear discharge, relieve pain and discomfort, and reduce the risk of complications such as hearing loss, balance problems, facial nerve damage, or spread of infection to the brain.

Mastoidectomy also aims to preserve and, in many cases, improve hearing, while creating a safe and dry ear for long-term ear health. It is a safe and effective surgical option when conservative treatments fail, significantly improving comfort, function, and overall quality of life.
