Investigation of the clinician satisfaction for the single-puncture and double-puncture arthrocentesis of temporomandibular joint

Aim: The aim of this study was to evaluate the clinician satisfaction of single-puncture arthrocentesis and double-puncture arthrocentesis in cadavers. Material and Method: The study was conducted on 10 fresh cadaver temporomandibular joints bilaterally. Single-puncture arthrocentesis was randomly conducted on one side chosen by coin toss and double-puncture arthrocentesis on the other side. The main outcome variable was clinician satisfaction and measured using 0-10 point Likert scale. Results: Twenty arthrocentesis procedures were completed. The mean clinical satisfaction scores for single-puncture arthrocentesis and double-puncture arthrocentesis were 8.1 and 4.8, respectively. A statistically significant difference was found between the techniques in terms of main outcome variable, and it was significantly lower in double-puncture arthrocentesis (p=0.001). Conclusion: Single-puncture arthrocentesis showed higher clinician satisfaction compared to double-puncture arthrocentesis.
