Abstract

Background: Temporomandibular joint dislocation occurs when the condyle moves beyond the anterior surface of the articular eminence, stays locked, and is unable to reduce itself back to the original position in the glenoid fossa. Nonsurgical options are preferred in management of TMJ dislocation
Aim: This study aims to compare between pericapsular injection of either platelet rich plasma or autologous blood for the management of recurrent dislocation of TMJ.
Subjects and methods: Forty patients suffering from chronic recurrent TMJ dislocation were selected in this prospective cross-sectional study. Patients were divided into two groups: Group I for 20 patients who were treated by injection of autologous blood; 2 ml into the pericapsular tissues of the TMJ, and Group II for 20 patients were treated by injection of platelet rich plasma; 2 ml into the pericapsular tissues of the TMJ. Patients were evaluated as pain score and range of mandibular movements.
Results: The mean age of patients was 30.2 years, 20% of patients were male and 80 % of patients were female. There is highly significant difference among studied groups as comparing preoperative and postoperative values after one or 3 months for pain assessment and lateral range of mouth opening.
Conclusion: Both autologous blood and PRP are simple, low cost, and minimally invasive methods that allow a high concentrate of autologous growth factors in physiological proportions to be obtained from blood, which can be easily and safely injected directly into the TMJ. Higher levels of pain associated with whole blood injection.
