Indications for mastoidectomy in acute mastoiditis in children.

The objective of this study was to identify clinical features of acute mastoiditis in children that are indicative of the need for mastoidectomy. We performed a retrospective chart review of 40 children (20 male, 20 female) between 2 months and 12 years 9 months of age with a diagnosis of acute mastoiditis who were managed in our institution between July 1998 and June 2002. All patients received intravenous antibiotics; this was the only treatment in 14 patients (35%). Tympanostomy tubes were inserted in 22 patients, together with postauricular needle aspiration in 12 (30%), and incision and drainage of subperiosteal abscess in 10 (25%). Mastoidectomy was performed in 4 cases (10%), and cholesteatoma was found in 3. One other child was subsequently found to have cholesteatoma. We conclude that children who present with acute mastoiditis should undergo mastoidectomy if cholesteatoma is clinically suspected, or if extratemporal suppurative complications have occurred.
