Outcome of Temporalis Fascia Myringoplasty With and Without use of Platelet Rich Plasma: A Randomized Control Trial.

To compare efficacy of temporalis fascia myringoplasty using platelet-rich plasma(PRP) {MP-PRP} and conventional emporalis fascia myringoplasty (MP-C) in treatment of moderate to large central tympanic-membrane(TM) perforation. Randomized-Control-Trial. We randomly assigned eighty-patients with COMmucosal-type with medium to large central TM-perforation and conductive hearing loss planned for primary myringoplasty to receive either MP-PRP orMP-C. Myringoplasty was performed through postauricular approach underlay graft using temporalis fascia. Primary-outcome was graft uptake (an intact TM) at 6 months postoperatively. Secondary-outcome was the postoperative hearing improvement measured by pure-tone-audiometry (PTA). Eighty-myringoplasties (MP-PRP group-40, MP-C group-40) done for 80 patients (male = 41; female = 39, age-group = 18-45-years) were included in analysis. At 6 months postoperatively graft uptake rate was 94.4% in MP-PRP and 92.1%% in MP-C group. There was no statistically significant difference in graft-uptake between the two groups (= 0.358). Success in terms of hearing gain (≥ 10 dB) was achieved in 34 patients (89.5%) in MP-C and 37 patients (94.9%) in MP-PRP group. At 6 months follow-up; mean-PTA-average improved from 35.10 ± 5.401 dB to 27.74 ± 5.660 dB and mean ABG improved from 24.00 ± 5.204 dB to17.42 ± 5.559 dB in MP-C group. At 6 months followup; mean-PTA-average improved from 37.00 ± 6.144 dB to 26.65 dB and mean air bone gap (ABG) improved from 25.98 ± 5.736 dB to 16.21 ± 4.318 dB in MP-PRP group. No statistically significant differences in improvement in PTA-values were observed between both groups ( = 0.336).Postoperative complications were similar in both groups. Graft-uptake, hearing outcomes and complications of MP-PRP were similar to MP-C. MP-PRP offers no advantages over MP-C for treatment of TM perforation.
