Abstract
The efficacy of adenoidectomy in the treatment of serous otitis media was evaluated by tympanograms of 54 patients (107 ears) recorded before and after adenoidectomy and adeno-tonsilectomy.
1) About half the B-type and most of the C-type tympanograms improved to A-type after surgery.
2) Clinical progress was more favorable when myringotomy preceded surgery.
3) The results were less favorable in children under 5 years of age.
4) Better results were noted in patients treated with tonsilectomy in addition to adenoidectomy.
5) A favorable clinical course was noted in patients with (+)-(++) cloudiness on X-rays of the para-nasal sinuses.
6) Improvement of the tympanogram was observed frequently 1-2 months after operatlon.
