REVISION MYRINGOPLASTY

This retrospective study was undertaken to review the short- and long- term results of 70 revision and 16 re-revision myringoplasty operation s. Of the former, 43 cases (61.4 per cent) had initial success, six we eks following surgery. The leading causes of immediate failure (27 cas es) were associated with a complete no-take of the graft, infection wi th graft necrosis and poor anterior adaptation of the graft in decreas ing order. Six out of the 43 patients developed late re-perforations d uring the follow-up period, thus reducing the success rate of revision myringoplasty to 52.8 per cent. Late re-perforations were attributed to insidious atrophy of the tympanic membrane or episodes of acute oti tis media. Sixteen patients underwent re-revision myringoplasty and th eir success rate was 62.5 per cent. The overall success rate of revisi on and re-revision myringoplasty was 54.7 per cent. It has been conclu ded that results of revision myringoplasty were independent of patient s' age, location and size of perforation and the seniority of the surg eon.
