Purpose: It remains a point of controversy whether or not evidence of joint effusion (JE) in magnetic resonance imaging (MRI) of temporomandibular joints (TMJ) may be linked to joint pain (JP). Previous studies had problems with the evaluation of pain because they compared JP between patients. Furthermore, JE had been evaluated subjectively by categories. In order to solve these problems, we quantified JE by MRI and designed a longitudinal study to compare JE and JP before and after arthrocentesis for TMJ. The aim of this study was to evaluate the relationship between JP and JE.<BR>Patients and Methods: The subjects were 24 patients who underwent arthrocentesis for unilateral internal derangement or osteoarthritis of TMJ between January 1999 and June 2002. MRI was performed before and after arthrocentesis in all patients. The subjects consisted of 2 men and 22 women. Their mean age was 28.5 years (range 16-61). On T 2-weighted images, JE was identified as an area of high signal intensity in the upper joint space, and was evaluated on sagittal T 2-weighted images. We measured the area of JE using image analysis software (NIH Image) and calculated its volume by the expression:<BR>Vol<SUB>eff</SUB>=∑ (Ar<SUB>eff. i</SUB>×ST) (Vol<SUB>eff</SUB>: volume of JE, Ar<SUB>eff. i</SUB>: area of JE in slice i, ST: slice thickness)<BR>JP was evaluated using a visual analog scale (VAS). We classed patients into a pain improvement group and inefficacy group and an examined changes of JE and VAS in each patient before and after arthrocentesis.<BR>Results: In the pain improvement group, 19 joints were improved, and in the inefficacy group, 5 joints were improved. JE and VAS of the pain improvement group significantly decreased after arthrocentesis. There was no significant difference in JE or VAS of the inefficacy group before and after arthrocentesis.<BR>Conclusion: These results imply that a relationship exists between JE and JP.
