The effect of adenoidectomy on secretory otitis media in children.

139 patients, 80 boys and 59 girls aged 1 1/4--13 1/2 years suffering from serous otitis media based on otoscopy and tympanometry had adenoidectomy performed and no other surgical measures taken. The efficiency of the treatment was assessed 2--4 months later. Intially flat tympanometry curves were found in 155 ears, negative middle ear pressure in 70 ears and low curves in 20 ears. 78% of all ears and 73% of the ears with flat curves were seen to normalize during the observation periods.
