Postoperative Assessment of Platelet-Rich Plasma and Platelet-Rich Fibrin in Temporomandibular Joint Surgery

NCT07359131 · Status: NOT_YET_RECRUITING · Type: OBSERVATIONAL · Enrollment: 700

Last updated 2026-01-23

No results posted yet for this study

Summary

The goal of this observational study is to evaluate postoperative outcomes following temporomandibular joint (TMJ) surgery and to compare the effectiveness of intraoperative platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) injections in patients with temporomandibular joint disorders.

The study includes adult patients who underwent TMJ surgery and received either PRP or PRF intraoperatively. The main questions this study aims to answer are:

Whether intraoperative PRP or PRF injection is associated with differences in postoperative pain intensity and recovery.

Whether PRP and PRF differ in their effects on postoperative jaw function, including maximum mouth opening and joint symptoms.

If there is a comparison group: Researchers will compare patients who received intraoperative PRP with those who received intraoperative PRF to assess differences in postoperative pain, functional outcomes, and joint-related symptoms.

Participants will:

Have their existing medical records reviewed retrospectively.

Provide postoperative outcome data derived from routine clinical follow-up, with no prospective recruitment or intervention.
