Objective: To evaluate the effect of PRP-enriched gelfoam on the healing of chronic TM perforation in comparison with gelfoam alone. Methods: In this double-blind randomized clinical trial Patients with chronic tympanic membrane were randomly allocated to two groups; intervention group underwent tympanoplasty with platelet rich plasma (PRP)- enriched gel foams and control group underwent operation with conventional gel foams alone. Patients information was recorded 4 and 12 months after surgery. Results: Eventually 24 patients (12 males and 12 females) with a mean age of 43.33 ± 12.34 years in intervention and 41.33 ± 10.02 years in control group underwent analysis (p = 0.667). Complete TM healing was seen in 8 (66.67%) patients in intervention group and 3 (25%) patients in control group three months after intervention (p = 0.031, OR = 5.98). Conclusion: Addition of PRP to conventional gelfoams used in TM perforation repair increases the complete healing rate of TM perforation with less morbidity and complications.
