METHODS: Twenty-nine patients undergoing transcanal endoscopic type 1 cartilage tympanoplasty were included in this controlled prospective clinical study. Patients were randomly assigned to platelet-rich fibrin (n = 14) or absorbable gelatine (n = 15) groups. Preoperative and postoperative pure-tone audiometry results, graft healing rates, tympanometry values, and Glasgow Benefit Inventory scores were compared. RESULTS: No significant postoperative complications were observed and the graft intake rate was 100% in both groups. Mean aft-bone gap gain was 9.82 +/- 4 dB HL in the postoperative first month and 10.08 +/- 491 dB HL in the sixth postoperative month in the platelet-rich fibrin group. There was no statistically significant difference between the postoperative air-bone gap gains of the groups in the first (P= .537) and sixth month (P= .723) controls. There was no statistically significant difference in compliance (P = .453) between groups. The physical benefit scores of the Glasgow Benefit Inventory were significantly higher in the platelet-rich fibrin group (P= .01).There was no difference in general and sodas benefit scores (P> .05). CONCLUSION: As a middle and external auditory canal packing agent, platelet-rich fibrin was as successful as absorbable gelatine in transcanal endoscopic cartilage tympanoplasty with similar functional results and graft healing rate.en10.5152/iao.2022.21378info:eu-repo/semantics/openAccessCartilageendoscopic tympanoplastygelfoamplatelet-rich fibrinTympanic Membrane PerforationsRepairArticle185405410WOS:0008659849000052-s2.0-8513716398135971267Q3Q4
