A mastoidectomy is a surgical procedure that involves the removal of infected or diseased tissue from the mastoid bone, which is located behind the ear. This surgery is often performed to treat chronic ear infections or complications from conditions like otitis media. The goal is to clear the infection and prevent further damage to the ear and surrounding structures. During the procedure, a surgeon makes an incision behind the ear to access the mastoid bone. They may remove part of the bone and any infected tissue to restore normal ear function. Recovery typically involves monitoring for complications and managing pain, with follow-up care to ensure healing.
