Abstract
Purpose: To assess and compare the clinical and radio- graphical effectiveness of low versus high, hydraulic pressure arthrocentesis for patient suffering from anterior disc displacement without reduction. Patients and Methods: The current study was conducted on twenty patients, all of them are females ranging from 20 to 50 years (mean 30 years). History, clinical and radiographic examinations (MRI) were used to select those patients suffering from anterior disc displacement without reduction (closed lock). The included subjects underwent MRI after arthrocentesis in not more than two weeks interval. The selected patients were randomized into two equal groups. The first group included 10 females (mean age of 30 years) and were treated by single needle arthrocentesis with application of high pressure during irrigation. While second group involved 10 females (mean age of 31 years) and were treated with single needle arthrocentesis with application of low pressure during irrigation, follow up was for three months
