Comparison of intraarticular injection of platelet-rich plasma following arthrocentesis, with sodium hyaluronate and conventional arthrocentesis for management of internal derangement of temporomandibular joint.

AIM: The aim of the study is to compare the efficacy of platelet-rich plasma (PRP) for the management of internal derangement of temporomandibular joint (TMJ).

SETTINGS AND DESIGN: Thirty-three patients were selected from the pool of patients visiting the department of oral and maxillofacial surgery. Simple randomization was done.

SUBJECTS AND METHODS: Patients with anterior disc displacement without reduction (DDWOR) were indicated for arthrocentesis. Group A patients are treated with PRP, Group B patients with sodium hyaluronate following arthrocentesis, and Group C patients were treated with arthrocentesis alone. Postoperative pain and maximal incisal opening are the primary outcomes evaluated.

STATISTICAL ANALYSIS USED: The collected data were analyzed with IBM. SPSS statistics software 23.0 version and the one-way ANOVA with Tukey's post hoc test were used.

RESULTS: The mean age is 33 years, with female predominance. The statistical significant differences ( P < 0.05) in pain and MIO between the 3 groups at the end of 3rd week, 4th week, and 3rd month postoperatively are seen in PRP group comparative to other groups.

CONCLUSIONS: Our study has concluded that the intraarticular injection of PRP is an effective management for anterior DDWOR of TMJ than intraarticular injection of sodium hyaluronate and arthrocentesis in, reducing the pain and improving the interincisal distance in patients with DDWOR, thus providing a rapid recovery and improved quality of life.
