Autologous PRP has been shown to be safe and effective in promoting natural wound healing processes. This study assessed the efficacy of fat graft myringoplasty combined with PRP in tympanic membrane (TM) healing in dry TM perforation due to chronic otitis media and compared it to that of fat graft myringoplasty.Methods: A systematic review and meta-analysis of prospective or retrospective studies was conducted, with database searches (PubMed, Cochrane Library, Embase, Web of Science, Scopus, and Google Scholar) performed through April 2025. The outcomes included the success rate (complete closure of the TM postoperatively) and changes in air-bone conduction gap (ABG) (preoperatively and postoperatively) in the audiogram.Results: Five studies (n=522) were included. Fat myringoplasty with PRP resulted in greater improvement in ABGs (standardized mean difference [SMD], 0.329; 95% CI, 0.132 to 0.527) and higher success rates (odds ratio [OR], 3.129; 95% CI, 1.882 to 5.203) compared to fat myringoplasty alone. In medium-sized perforations, combination therapy demonstrated superior outcomes in both success rate (OR, 3.179; 95% CI, 1.891 to 5.343) and ABG (SMD, 0.357; 95% CI, 0.128 to 0.586). However, no significant differences were observed in cases involving small and medium-sized perforations (success rate: OR, 2.154; 95% CI, 0.174 to 26.672 and changes in ABG: SMD, 0.249; 95% CI, \u20130.141 to 0.638). Both liquid and gel PRP significantly improved ABGs and TM closure rates, with no significant difference between types.Conclusion: This study demonstrated a higher success rate and greater hearing improvement with PRP-assisted fat myringoplasty, especially in medium-sized perforations. Both liquid and gel PRP forms were effective, with no significant difference between them.<\/jats:p>","DOI":"10.21053\/ceo.2025-00157","type":"journal-article","created":{"date-parts":[[2025,8,13]],"date-time":"2025-08-13T10:13:09Z","timestamp":1755079989000},"page":"70-78","update-policy":"https:\/\/doi.org\/10.21053\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Efficacy
