The ENT specialist will diagnose the mastoiditis with an examination of the ear. The doctor may suggest some tests that may confirm a diagnosis, they include CT scan, MRI, X-ray, blood tests, fluid culture, hearing test, and lumbar puncture or spinal tap.
An ENT doctor will recommend the surgery when medications and other ear treatments don't prove to be fruitful. The purpose of mastoidectomy surgery is to remove the diseased mastoid air cells located behind the ear. The diseased air cells are the root cause of ear infection in adults that may spread into the skull if untreated. It is performed under general anesthesia where a microscope is used for more precision. There are variations of mastoidectomy, simple mastoidectomy, radical mastoidectomy, and modified radical mastoidectomy.
