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.
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.
Forty patients with Wilkes III temporomandibular joints (TMJ) internal derangement were identified and 13 patients who met the inclusion criteria were reviewed. The main outcomes regarding the clinical applicability of modified CCT included the duration of arthrocentesis, the number of reposition of cannula, and the occurrence of complications.
The values of maximum mouth opening (MMO) without pain and MMO without assistance measured in the immediate postoperative period and at the 4th and 8th postoperative weeks were found to be significantly higher than the pre-arthrocentesis values. The values of MMO with assistance measured in the immediate postoperative period and at the 8th postoperative week were also significantly higher than the baseline values. Compared with preoperative values, notable decreases in pain scores were observed at the 4th (p = 0.003) and 8th (p = 0.002) postoperative weeks. The assessment of the jaw dysfunction also revealed significantly lower scores at the 4th (p = 0.024) and 8th (p <0.001) postoperative weeks.
Modified CCT of arthrocentesis substantially decreased pain and improved mandibular functions in patients with internal derangement of TMJ. Additionally, this technique could be performed with a reduced number of cannula relocations and required a shorter operative time even with the use of a higher irrigation volume during the lavage procedure.

确定改良同心套管技术（CCT）的临床适用性，重点关注关节穿刺的持续时间、套管重新定位的次数和并发症的发生。
描述性研究。研究地点和时间：土耳其安卡拉 Yildirim Beyazit 大学口腔颌面外科，2021 年 9 月至 2022 年 5 月。
确定了 40 例 Wilkes III 颞下颌关节（TMJ）内部紊乱的患者，回顾了符合纳入标准的 13 例患者。改良 CCT 临床适用性的主要结果包括关节穿刺持续时间、套管重新定位次数和并发症发生情况。
术后即刻、第 4 周和第 8 周测量的无痛最大张口度（MMO）和无需辅助的 MMO 值明显高于关节穿刺前的值。术后即刻和第 8 周测量的辅助 MMO 值也明显高于基线值。与术前值相比，术后第 4 周（p = 0.003）和第 8 周（p = 0.002）疼痛评分显著降低。对咀嚼功能障碍的评估也显示术后第 4 周（p = 0.024）和第 8 周（p <0.001）评分明显降低。
改良 CCT 关节穿刺术可显著减轻 TMJ 内部紊乱患者的疼痛，改善下颌功能。此外，即使在灌洗过程中使用更高的冲洗量，该技术也可以通过减少套管重新定位的次数和缩短手术时间来完成。
