Overview

Topical autologous platelet-rich plasma (PRP) significantly reduced postoperative pain and improved wound healing in patients undergoing tonsillectomy. A randomized controlled trial involving 200 patients demonstrated these benefits compared to a platelet-poor plasma control.

Background

Post-tonsillectomy pain management remains a critical aspect of patient recovery, with traditional approaches often relying on nonopioid analgesics. The introduction of adjunct therapies like PRP could enhance recovery outcomes by addressing pain and promoting healing. Understanding the efficacy of PRP in this context is essential for optimizing postoperative care.

Data Highlights

Outcome	PRP Group	Control Group
Mean Pain Score Day 1	6	7
Mean Pain Score Day 8	1	2
Complete Mucosal Healing by Day 14	78%	59%
Secondary Hemorrhage Rate	2%	5%

Key Findings

PRP application resulted in a mean pain score reduction of −0.8 points on the visual analog scale over 10 days.
Statistically significant pain differences were observed from postoperative days 1 to 8.
Complete mucosal healing by day 14 was achieved in 78% of patients receiving PRP.
No patients in either group experienced wound infection or abnormal granulation tissue.
Secondary hemorrhage occurred in 2% of the PRP group compared to 5% in the control group.

Clinical Implications

The use of topical PRP during tonsillectomy may serve as an effective adjunct to standard pain management protocols, potentially leading to improved patient comfort and faster recovery. Clinicians should consider incorporating PRP into their postoperative care strategies for tonsillectomy patients.

Conclusion

Topical autologous PRP shows promise in enhancing recovery following tonsillectomy by reducing pain and improving wound healing. Further studies are warranted to confirm these findings and establish PRP as a standard adjunct therapy.
