Treatment of temporomandibular joint disc displacement using arthrocentesis combined with injectable platelet rich fibrin versus arthrocentesis alone

Abstract

Background/purposeTemporomandibular joint disc displacement is the most frequently reported temporomandibular disorder that may severely impair quality of life and can be challenging to treat. This study aimed to evaluate and compare the efficiency of intra-articular injection of injectable platelet rich fibrin (i-PRF) following arthrocentesis or arthrocentesis alone in treatment of patients with TMJ disc displacement with reduction. Materials and methodsForty patients for a total of forty joints with reducible anterior disc displacement, as confirmed by Magnetic Resonance Imaging (MRI) were selected and divided into 2 equal groups. In group I (control group), arthrocentesis alone was performed with Ringer solution. In group II (study group), a combination of arthrocentesis and intra-articular injection with 1.5 ml i-PRF was performed. The outcome variables included pain intensity evaluated with a visual analogue scale, inter-incisal opening, lateral movement evaluated in millimeters, and clicking. Assessments were done pre-operatively, and 1 week, 3 months, and 6 months postoperatively. ResultsThere was statistically significant reduction in pain intensity and clicking sound and increase in mouth opening and lateral movement in i-PRF group when compared to arthrocentesis group. In addition, the differences between preoperative and postoperative status in all the measured parameters were statistically significant within the study and the control group throughout the postoperative period. ConclusionThe combination of i-PRF with arthrocentesis is a safe and effective method in the treatment of TMJ disc displacement with reduction.
