Tympanoplasty was combined with tubulation of the drum remnant with grummets in 74 patients with severe adhesive changes in the middle ear. 40 ears were dry at the time of operation, 34 were chronically discharging, and in such cases mastoidectomy with cavity obliteration and tympanoplasty were performed in the same session. The initial results (3–9 months after the operation) and later follow-up results (18 months to 4 years later) are presented and discussed in relation to tubal function. As a rule, the tubule was expelled 2–4 months after the operation, but during the postoperative period it contributed to aeration of the middle ear and prevented atelectasis, especially in patients whose Eustachian tube was not passable in Valsalva’s maneuver after the operation. Initially after the operation the mean hearing was 29.7 dB, at late follow-up 33.2 dB. The relatively slight decrease in hearing at late follow-up may be ascribed to the favorable effect of tubulation during the postoperative period.
