== Usages == Historically, trephination was used to potentially relieve intracranial pressures or build-up of pus, with records dating back to pre-historic times. Over time, these became formalized as mastoidectomies. Mastoidectomies were used to treat infections such as otitis media, or abnormal skin cell growth near the middle ear. Over time, they were adapted to help treat hearing issues such as tinnitus.
