    Abstract:
    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. METHODOLOGY: 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. RESULTS: 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. CONCLUSION: 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.
