Objective: We aimed to evaluate the effect of autologous platelet-rich plasma gel (PRPG) on fat graft myringoplasty (FGM) in tympanic membrane perforations caused by chronic otitis media. Methods: This retrospective study involved 63 patients who underwent operations between 2015 and 2018. Fat graft myringoplasty was performed with the transcanal approach with and without the use of PRPG in the surgical field. The patients were classified into 2 groups: group A, which included 32 patients who underwent FGM with the use of autologous PRPG, and group B, which included 31 patients who underwent FGM alone. Tympanic membrane perforations were divided into 2 groups: small perforations (1-2 mm) in a single quadrant and large perforations (2-4 mm) in at least 2 quadrants. Results: Both groups were statistically matched regarding age and sex. The mean postoperative follow-up was 11.6 and 12.1 months for groups A and B, respectively. Four months postoperatively, the success rate of the graft in group A (100%) was significantly higher than that in group B (83.8%; P = .03). The preoperative and postoperative median air–bone gaps of the groups were similar ( P = .653 and P = .198, respectively). No worsening of the air–bone gap was noted postoperatively in either group. Conclusions: This study demonstrated that autologous PRPG application during FGM allows for a higher success rate than FGM alone. Furthermore, the use of PRPG with FGM for large perforations increases the success rate. Further studies are needed to investigate the PRPG healing effect on other tympanic membrane perforation closure techniques.
