1-25. SIMPLE MASTOIDECTOMY

a. General. Simple mastoidectomy involves the removal of the air cells of the mastoid process without disturbing the contents of the middle ear. It may be done occasionally to treat acute empyema (accumulation of pus) of the mastoid, but has been made almost obsolete by antibiotics.

b. Operative Procedure. A postural or endaural incision is made. Perform procedures for a radical mastoidectomy as stated in paragraphs 1-24c(1), (2), (3), and (6).

NOTE: A modified radical mastoidectomy may also be done in which the middle ear

is not involved, but in which the thin bridge of bone between the external

canal wall and antrum is removed.
