This study aims to compare two different single-puncture arthrocentesis (SPA) Type 2 techniques, the Y-shaped cannula and the concentric needle methods, in terms of intraoperative parameters. In the study, data from 32 unilateral temporomandibular joint (TMJ) arthrocentesis procedures, including procedure duration (seconds), the number of cannula relocations, and procedural difficulty (evaluated using a visual analog scale), were retrospectively analyzed. The Y-shaped cannula technique was found to significantly reduce procedure duration (284.81 ± 74.6 s vs. 649.50 ± 118.9 s, p < 0.001). Although there were no significant differences between the groups in the number of cannula relocations or procedural difficulty, analysis of covariance (ANCOVA) showed that the Y-shaped cannula technique made the procedure less difficult (p = 0.018). These results suggest that the Y-shaped cannula may offer advantages, particularly in busy clinical settings, by shortening procedure duration and facilitating ease of operation.

This study aimed to evaluate and compare the efficacy of single-puncture techniques in temporomandibular joint (TMJ) arthrocentesis for the management of disk displacement without reduction (DDwoR). A total of thirty-six patients diagnosed with DDwoR were randomly and blindly assigned to two treatment groups (N = 18 each): Group 1 underwent TMJ arthrocentesis using a concentric needle-cannula system with protrusive movements, while Group 2 received TMJ arthrocentesis with a concentric needle-cannula system but without protrusive movements. The following variables were recorded and compared between the groups: maximal interincisal distance (MID - mm), patient pain perception (visual analogue scale - VAS [0-10]), and operation duration (OP - minutes).

Introduction/aims: In healthy subjects, we observed high amplitude motor unit potential (MUP) waveforms that resembled the cannula potential (CP) with a positive sharp wave (PSW)-like waveform. We analyzed the source of this signal, its prevalence, and its effects on the analysis of electromyographic waveforms.
Methods: Three channel recordings were performed to explore the contribution of the needle core and cannula to the MUP.

Article Synopsis
- The text discusses a new technique for treating temporomandibular joint osteoarthritis (TMJ-OA) using real-time ultrasound guidance to directly inject medications into the subchondral bone.
- This method involves using a specialized ultrasound device to precisely guide a cannula into the mandibular condyle, ensuring that the treatment targets the area most affected by the condition.
- Results showed that the technique is reliable and may offer a significant improvement in TMJ-OA management, particularly when the cortical bone is still intact.

Objective: To determine the clinical applicability of the modified concentric cannula technique (CCT), focusing on the duration of the arthrocentesis, the number of reposition of cannula, and the occurrence of complications.
Study Design: Descriptive study. Place and Duration of the Study: Department of Oral and Maxillofacial Surgery, Ankara Yildirim Beyazit University, Ankara, Turkiye, between September 2021 and May 2022.
