OBJECTIVE: There are no direct comparisons between the success of collagen allografts versus traditional autografts for tympanic membrane (TM) repair. We sought to compare success rates in a large series of patients undergoing tympanoplasty using collagen allografts versus autologous tissues. STUDY DESIGN: Retrospective review. SETTING: Academic medical center. SUBJECTS AND METHODS: Single institution retrospective chart review was performed for adult subjects with TM perforation undergoing tympanoplasty. Demographic, clinical, and surgical data were collected. Statistical analysis was completed using Rstudio. Each factor was examined to assess effect on graft success rate using logistic regression. RESULTS: Two hundred sixty-five surgeries met criteria with four main grafting materials or combinations thereof. The overall graft success rate was 81.1% with failure rate of 18.9%. There was no significant association between failure rates and: age, sex, perforation cause, size, and location, primary or revision status, middle ear status (wet or dry), concomitant procedures (mastoidectomy or ossiculoplasty), presence of active cholesteatoma, or surgical technique. Although not statistically significant, the odds of success for perichondriumâ+âcartilage were 7.5 times higher than collagen allografts (pâ=â0.07, 95% confidence interval [CI]â=â0.81-69.6). The odds of success for the postauricular (odds ratio [OR]â=â6.4) and transcanal approaches (ORâ=â24.8) were significantly greater than for endaural (pâ=â0.007 and pâ=â0.008, respectively). CONCLUSION: In tympanoplasty surgeries performed on patients with TM perforation, we found no statistically significant difference in graft failure rates between collagen allograft and other grafting materials or combinations, though the higher odds ratio of success with cartilageâ+âperichondrium may be clinically relevant.
