Abstract
The successful surgical treatment of chronic otitis media or its sequela is frequently related to a ventilated tympanic cavity. Tubes at tympanoplasty have been recommended to assure ventilation until eustachian tube and middle ear mucosal functions have been restored and to prevent the complications of graft loss, atelectasis, cholesteatoma and ossicular destruction. This presentation reviews the literature on the subject and documents our results in 40 patients treated by tympanomastoid surgery with ventilating tubes. The types of tubes used, the surgical technique involved, and the selection of cases suitable for this method are described. Cholesteatoma was the primary disease in 32 patients, 6 had chronic otitis media, 1 cholesterol granuloma, and 1 eosinophilic granuloma. Complete healing of grafts following extrusion or removal of the tubes occurred in 34 patients, 2 tubes remain in place, 3 patients had persistent tube site perforations, and 1 was lost to follow-up. None of the patients had graft breakdown as a result of tube placement, and there has been no recurrence of cholesteatoma. In all cases, the follow-up period is a minimum of 18 months and extends to 92 months.
