Quantitative evaluation of normal uptake of mandibular condyle in bone scan with Tc99m-MDP

Unilateral condylar hyperplasia is the main cause of mandibular asymmetry. Radionuclide bone scanning is a useful procedure for functional evaluation of temporomandibular joint. In this study, 39 patients with normal bone scan and no facial asymmetry were studied. All patients were below 22 years of age. Normal condylar uptake was determined in this group of patients. Right and left condylar uptakes were not completely identical and some difference [Below 10%] between right and left condylar uptake was seen. No significant difference in condylar uptake in male and female patients were observed [P=0.26, alph=0.05]
