From 2000 to 2002, we treated 9 cases (4 males and 5 females) of acute mastoiditis following acute otitis media. Most of these cases complained of otalgia, otorrhea and hearing loss, and one each had retroauricular swelling and headache. Four cases had serious complications such as facial nerve palsy, subperiosteal abscess, bacterial meningitis, labyrinthitis and Gradenigo syndrome. All patients revealed mixed hearing loss on pure-tone audiometry and all but 1 case showed complete recovery of hearing. Etiological bacteria from the middle ear were cultured and there were 2 cases each of Streptococcus pneumoniae and Staphylococcus aureus. 3 patients were cured by conservative therapy consisting of intravenous antibiotics, myringotomy or insertion of a ventilation tube. Six patients underwent surgical therapy with a simple mastoidectomy and postoperative antibiotic therapy. Facial nerve decompression was performed in 1 case.<br>The clinical features and conservative or surgical intervention of mastoiditis are discussed.
