Objective:
Arthrocentesis is an effective procedure for management of symptomatic patients with temporomandibular joint (TMJ) anterior disc displacement without reduction (ADDWOR), but its prognostic factors are still under investigation.
Methods:
Thirty-six patients with ADDWOR underwent arthrocentesis of the TMJ and hyaluronic acid injection. They were divided into groups based on three prognostic factors: Age, gender, and the presence of parafunctional habits. The procedure outcome (success or failure) was based on pre-set criteria for improvement in pain and maximum mouth opening (MMO) one month preoperatively.
Results:
Patients with parafunctional habits had a lower success rate than patients without these habits. Interesting trends were noted with age and gender as prognostic factors for arthrocentesis for patients with ADDWOR.
Conclusion:
Arthrocentesis is an effective management method for symptomatic patients with ADDWOR at one-month post treatment, especially in the absence of parafunctional habits.
