Abstract

AIM: the aim of this study was to compare patient satisfaction and the clinical outcome of single needle approach versus double needle technique in treating patients with anterior disc displacement without reduction.
Patients and Methods: This was a randomized controlled trial conducted on 14 adult (13 females and 1 male) patients with anterior disc displacement without reduction with limiting opening. In control group, double needle TMJ arthrocentsesis was performed with 100 ml ringer’s lactate solution. While in the test group, single needle TMJ arthrocentsesis was performed with 21 ml ringer’s lactate solution. All patients were followed up for 3 months. Pain level and maximum mouth opening were evaluated in both groups.
Results: Both groups showed a significant improvement throughout the study intervals.
Conclusions: Single needle arthrocentsesis represents a reliable treatment modality for the management of patients suffering from closed lock. However the exact amount of irrigation solution needed to achieve the maximum therapeutic benefits from this technique is a point that needs further investigations.
