1-24. RADICAL MASTOIDECTOMY
a. General. Radical mastoidectomy involves the removal of the mastoid air cells, the tympanic membrane, the involved malleus, incus, chorda tympani, and mucoperiosteal lining which converts the middle ear and the mastoid into one cavity. This procedure may be used to treat a chronic otitis media (inflammation or infection of the middle ear) that has spread into the mastoid air cells, and when skin from the external auditory canal has grown into the middle ear (cholesteatoma) where it acts as a foreign body. Radical mastoidectomy may also be done to provide adequate exposure in the treatment of facial nerve decompression to drain an extradural abscess in the bony labyrinth.
b. Preparation of Operating Room. This requires an extensive setup of instruments and other sterile items. These are set up in the appropriate sizes and numbers, as prescribed locally.
c. Operative Procedure.
