Mastoid surgery, or mastoidectomy, involves drilling a hole in the mastoid bone and removing the infected air cells. This procedure is performed under general anesthesia, and many patients return home later the same day. Afterwards, your ears will be bandaged, and there may be stitches. You might experience headaches, discomfort and numbness. You’ll likely be prescribed pain medication and antibiotics, and will need to return after a few days to have your bandages and stitches removed. You’ll need to keep your ear free of water, and avoid strenuous activity or anything that might create pressure on your ear (e.g. airplane travel). Complications are rare, but might include facial nerve paralysis, sensorineural hearing loss, vertigo, tinnitus, and a change in taste.
