Role of Arthrocentesis with and without steriod for internal derangement of TMJ

Purpose: This study was designed to investigate the efficacy of arthrocentesis and to compare it with arthocentesis with steroid in the treatment of temporomandibular joint (TMJ) internal derangements. Materials and Methods: 9 males and 11 females aged between 17 to 39 years comprised the study material in the department of Oral &Maxillofacial surgery at Govt Dental College Srinagar(India). The patients’ complaints were limited mouth opening, and TMJ pain .Arthocentesis was performed under all aseptic conditions. Clinical evaluation of the patients was done before the procedure, and 1 week and 6 months after postoperatively. Intensity of TMJ pain and maximal mouth opening were recorded at each follow-up visit. Results: Both the groups showed significant improvement in mouth opening and reduction in pain scores in the post-operative period however the addition of steroid didn’t improve the total outcome of the procedure. Conclusions:Arthocentesis is simple and safe procedure for the patients of internal derangement with closed lock but addition of steroid doesn’t, improve the results.
