The etiology of bullous myringitis (BM) is unknown. We speculated that BM involves middle ear barotrauma because of frequent bleeding in the tympanic membrane, including a patient with BM who strongly blew the nose.<br>We investigated 186 patients with BM aged one to 80 years old (average age; 8.83), including 16 patients with recurrent BM.<br>In six patients, BM was associated with blowing their nose. Patient ages ranged from 6 to 58 years old (average age; 32.7). None of the patients showed recurrent BM. Two patients had multiple bulla formations and 5 patients showed bleeding in the tympanic membrane. Among all 186 patients examined, 36 patients had multiple bulla formations and 78 of 181 patients demonstrated bleeding in the tympanic membrane.<br>These findings suggest that a sudden reflex of secretions and air from the nasopharynx into the middle ear could cause bulla formation on tympanic membrane.
