# Two versus single needle arthrocentesis of TMJ for internal derangement

## TL;DR

This study compares the effectiveness of using one versus two needles during arthrocentesis for treating TMJ internal derangement.

## Contribution

The study provides evidence that using two needles does not improve outcomes compared to one needle in TMJ arthrocentesis.

## Key findings

- Arthrocentesis improves symptoms in patients with TMJ internal derangement.
- Adding a second needle did not enhance treatment outcomes.
- Results were evaluated at 1 week and 6 months post-procedure.

## Abstract

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.
