Efficacy of Platelet Rich Fibrin in Myringoplasty.

OBJECTIVE

To determine the efficacy of usage of topical autologous platelet rich fibrin (PRF) in improving outcomes of myringoplasty regarding graft uptake and hearing improvement.

METHODS

This study was conducted in the ENT department of Holy Family Hospital, Rawalpindi, over a period of six months from August 2019 to January 2020. It was designed as a prospective single blinded randomized controlled trial. The study involved a total of 50 participants in whom myringoplasty was done through post auricular approach using underlay technique. In 25 patients topical drops of PRF were used. Outcomes were compared after three months with the control group (n=25), who underwent myringoplasty without PRF.

RESULTS

After three months follow-up, graft uptake was reported 78% and 52% in cases and controls, respectively (P=0.070). Mean hearing improvement was 18 dB and 6 dB in cases and controls, respectively (P=0.014). Postoperative infection occurred in 8% of the cases, and in 32% controls (P=0.037).

CONCLUSION

Topical use of Platelet-Rich Fibrin during myringoplasty results in improved graft uptake. Hence, resulting in much improved hearing, significant reduction in infection rates and decrease in perforation sizes.
