Eighty-three children between ages 0–12 years had mastoid surgery in the three year period 1986–88. The indications were acute mastoiditis (30 children), uncontrolled chronic suppurative otitis media (CSOM) (24 children), cholesteatoma (22 children) and a miscellaneous group (7 children). Forty-seven per cent of those with acute mastoiditis were under one year but the 27 per cent with cholesteatoma as the precipitating cause were 4–12 years. Twenty-three per cent had significant complications. Typmano-mastoid surgery was employed to resolve uncontrolled CSOM. Children were between 2–12 years and 62 per cent were below the 25th centile for weight. Seventy-nine per cent of the tympanic membrane grafts were successful. The children with cholesteatoma were between 3–12 years and 76 per cent were below the 25th centile for weight. Eight of them only presented after the onset of acute mastoiditis. One child had a definite congenital cholesteatoma. Only one had a pars flaccida origin of the cholesteatoma sac and only eight an origin from the postero-superior pars tensa. All had open cavity surgery. When the cavity was lined by temporalis fascia, healing was improved markedly.
