Quantitative assessment of pterygomasseteric hypertrophy.
The aim of this study was to quantify the pterygomasseteric hypertrophy in a clinical case with significant facial asymmetry and temporomandibular joint dysfunction. Magnetic resonance imaging (MRI) technique was used to measure the surface areas of affected and contralateral pterygomasseteric muscle groups on six coronal scans. The results suggest that MRI is a very effective method for quantification of muscular hypertrophy and better explanation of associated clinical findings, therefore motivating the need to preserve or restore the bilateral masticatory function.
