Introduction: Tympanic membrane perforation(TMP) is a common cause of visits to the otolaryngology clinic. For decades, various surgical methods and various grafts have been used to treat TMP. This study aimed to compare the efficacy of Butterfly Dermal Allograft(BDA) and Fat myringoplasty for the treatment of TMP.

Methods: We retrospectively analyzed 40 patients who underwent BDA (n = 20) and Fat myringoplasty (n = 20) for tympanic membrane perforation performed by a single surgeon between January 2019 and December 2021. The hearing outcomes, graft success rate, complications, operation time and hospital stay were recorded and compared between groups. Hearing outcomes were determined by pure-tone audiometry.

Results: There was no significant difference between the BDA and Fat groups regarding demographic characteristics. There was no significant
difference in the pre- and post-operative air conduction, bone conduction thresholds, and air-bone gap values between the two groups, but a significant audiologic improvement was observed in both groups (p < 0.05). In terms of recurrence of tympanic membrane perforation, postoperative otorrhea, and discomfort symptoms, there was no significant difference between groups(p>0.05). The operation time and hospital stay were shorter in the BDA group than in the Fat group (p < 0.05).

Conclusions: BDA myringoplasty is as safe and medically efficacious as Fat myringoplasty, shortens the operation time and hospital stay.
