PRP-Fibrin Glue for Pain Reduction and Rapid Healing in Tonsillectomy.

INTRODUCTION: Many ongoing challenges have been applied to reduce the considerable postoperative pain and increase wound healing after tonsillectomy, but they are still not optimally managed. This study applied autologous platelet-rich plasma (PRP) & platelet-rich fibrin glue (PRFG) to reduce pain and increase wound healing.

MATERIALS AND METHODS: PRP & PRFG were prepared from 26 patients' blood. At the end of the tonsillectomy, one tonsillar bed was selected randomly, PRP was injected, PRFG was applied topically on the bed wound, and the other sites were left untreated. The treated and untreated tonsillar beds were compared for pain and wound healing the next day, 3rd day, 6th day, 9th day, and 15th day.

RESULTS: There were no complications during and after the injection. The mean age was 24.76 ±5.54 years. In the treated beds in comparison to untreated beds, pain decreased marginally in 1st day (intervention:4.5±2.54, control:5.53±2.94, P-value=0.18) and 3rd day (intervention:3.92±2.96, control:4.8±2.82, P-value=0.276), and significantly in 6th day (intervention:2.3±2.46, control:3.92±2.6, P-value=0.026), 9th day (intervention:1.26±1.48, control:2.76±2.4, P-value=0.009) and 15th day (intervention:0.73±1.07, control:1.84±2.36, P-value=0.08) after surgery. Healing did not change in 1st day (P-value=1), changed marginally in 3rd day (P-value=0.2), and increased significantly in 6th day (P-value=0.001), 9th day (P-value=0.006), and 15th day (P-value=0.004) after surgery.

CONCLUSIONS: Autologous PRP injection & PRFG application offer an effective, safe, and non-invasive method for reducing pain and increasing wound healing after tonsillectomy.
