Two versus single needle arthrocentesis of TMJ for internal derangement

The efficacy of arthrocentesis with two needles compared with one needle for the treatment of internal derangement of temporomandibular joint (TMJ) is of interest. Fifty patients aged between 17 to 39 years comprised the study material in the department of Oral & Maxillofacial surgery at Govt Dental College Srinagar (India). 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. Arthrocentesis improves the symptoms of the patients with internal derangement with closed lock but addition of other needle didn't improve the results.
