[Modified butterfly cartilage tympanoplasty: retrospective study on 26 patients].

Objective: To assess the results of inlay butterfly tympanoplasty on dry perforation.

Study Design: Retrospective case study.

Patients: 26 patient (14 male, 12 female), mean age 38 years, ranged from 9 to 73. Mean follow up: 20 months.

Surgery: Inlay cartilage butterfly tympanoplasty performed under general or local anesthesia according to the technique originally described by Eavey, with our specific modifications (use of a dermatological punch).

Results: 92.3% of perforation closure was obtained; 2 residual perforations and 1 non-epithelialisation were observed. No iatrogenic cholesteatoma was observed. The mean preoperative to post operative four-tone air bone gap improved from 27.67 to 20.1 (mean gain 7.5).

Conclusion: Inlay butterfly cartilage tympanoplasty is a safe, efficient and easy technique. This technique need more prospective evaluation, and its place among other techniques of tympanoplasty needs to be precised.
