Surgical Outcomes of Pure-Fat Myringoplasty for Small Tympanic Membrane Perforations: A Retrospective Study and Summary of the Literature in the Last 10 Years

초록

Background and Objectives Fat myringoplasty is a simple, fast, and effective procedurefor repairing tympanic membrane (TM) perforations. The aim of this study is to evaluate thesurgical outcomes of pure-fat myringoplasty for small TM perforations at our hospital and reviewthe current knowledge regarding fat myringoplasty, with consideration of the effectivenessof additional substances used in the treatment of small TM perforations. Subjects and Method We retrospectively studied 41 patients who underwent pure-fat myringoplastyat our hospital from March 2008 through April 2019 and were followed up for atleast 2 months thereafter. Results Of 41 patients, 16 were males and 25 were females, with the mean age of 48 (male,9-75 years; female, 16-65 years). All perforations were classified as small perforations, rangingfrom 1% to 17% of the TM. The overall success rate was 92.7%, with the TMs of 3 patients(7.3%) failing to close. Air-bone gap (ABG) decreased in 19 out of 24 patients who underwentboth preoperative and postoperative pure tone audiometric examinations. The meanABG was 4.42 dB (n=24; paired-t test, p=0.001; 95% confidence interval, 1.77-7.07). The literaturereview revealed that TM closure success rate of over 80% was associated with pure-fatmyringoplasty, while the TM closure success rate for fat myringoplasty with additional substanceswas 85% to 100%. Conclusion Our study revealed a high TM closure success rate and good hearing outcomesare associated with pure-fat myringoplasty. Pure-fat myringoplasty seems to be sufficient forrepairing small TM perforations.
