Chronic serous otitis media in the adult.

Twelve adult patients with serous otitis media have been seen in a five-year-period. Five of seven patients with nasopharyngeal neoplasm have died, and one case of polyarteritis nodosa has also terminated fatally. The remaining four patients had benign pathology in the nasopharynx, including one case of branchial cyst. A group of patients with chronic nasopharyngitis but without otological involvement is also reviewed.
