Abstract
The objective of this study was to compare techniques for temporomandibular joint (TMJ) arthrocentesis intraoperatively and to determine the ease of performance of these techniques for the physician. A total of 33 TMJ treatments were done using single-puncture arthrocentesis (SPA) type 1, SPA type 2, and double-puncture arthrocentesis (DPA) (n=11 in each treatment group) between December 2013 and December 2017. A retrospective analysis of the duration of the procedure (minutes), occurrence of complications, number of cannula relocations, and ease of the procedure was performed. Ease of the procedure was measured using a Likert-type visual analogue scale (VAS; 0–10). All measurement variables were recorded intraoperatively, and related data were analyzed statistically. Significant differences were found between SPA type 2 and the other techniques in terms of procedure duration and ease of the procedure (P<0.05). No significant differences were found in the occurrence of complications or number of cannula relocations between the techniques (P>0.05). Compared to the other TMJ arthrocentesis techniques, SPA type 2 is easier, and physicians can perform it in a shorter time.
