Resolution of negative middle ear pressure is important in treating @entity2346 media with effusion (OME). We treated 34 @entity1 and 21 adults with OME by autoinflammation using a nose tube and balloon in the 16 months from June 2001 to September 2002. Of these, 7 @entity1 and 5 adults had been treated for 3 years or longer, and had had grommets inserted. In 49 ears of 27 early cases of @entity1 , 34 ears (69%) improved in tympanometric findings converting to @entity69182 , and 9 ears (18%) of type B converted to type C1. In 23 ears of 16 early cases of adults, 12 ears (52%) improved converting to type A from type B, C2, C5 and C1, and 3 ears (13%) to type C1 from type B. However, 4 ears of 4 @entity1 and 5 ears of 5 adults did not recover by autoinflammation. In 7 @entity1 with prolonged OME in whom grommets had been inserted, 5 recovered due to autoinflammation, whereas only one of 5 adults recovered. Of 6 @entity1 who had not recovered, 2 were associated with @entity565 and @entity1412 and eosinophils infiltrated into the @entity2171 . In other 2 @entity1 , even when the @entity2171 disappeared by grommets insertion, they had still dysfunction of the Eustachian tubes confirmed by sonotubometric examination. It seems no beneficial effects of autoinflammation were maintained if @entity1 had @entity409 due to intensive inflammatory changes of the @entity2172 or other unknown origin. Two @entity1 used the device irregularly and rarely. There is a theoretical risk associated with this maneuver of causing baroinjury and forcing infected nasopharyngeal secretions into the middle ear, but we found no complications.
