Study on use of platelet-rich plasma in myringoplasty

Aim: This study aims to analyze the use of autologous platelet-rich plasma (PRP) to improve graft uptake and benefit on hearing after myringoplasty. Objectives: The objective is to compare pre-and post-operative graft uptake and audiological benefit following myringoplasty with and without PRP. Materials and Methods: A total of 70 patients diagnosed with chronic suppurative otitis media tubotympanic type were divided into groups of 35 each. Patients in group one who underwent myringoplasty with PRP while in second group underwent myringoplasty without PRP. Pre-and post-operative graft status and pure tone audiometry were performed for all the patients, and the outcomes were compared. Results: Of 35 patients in each group; four in the study group and eight in the control group had residual perforation. Graft uptake in case group was 88.57% and graft uptake in the control group was 77.1%. Result was better in cases that underwent myringoplasty with PRP. Of 35 patients in case group, audiological improvement (>10 dB) was seen in 31 patients (88.57%), whereas in the control group of 35 patients, 27 (77.1%) had audiological benefits. Conclusion: This study shows there is a definite benefit using PRP in myringoplasty. As the PRP can be easily prepared, PRP myringoplasty can be routinely performed.
