Abstract

A case of facial asymmetry with severe unilateral hypoplasia of the masticatory muscles is reported. A 45-year-old Japanese man was referred to our clinic on Dec. 18, 2002 with chief complaint of dull pain of the right masseter and molar teeth during chewing. He presented with left side facial hypoplasia which had been noted from an early age. The external ear was normal, the ears symmetrically placed and audition showed no abnormality. Maximal mouth opening was 58mm and the mandible did not deviate upon opening the mouth. Radiographic examination did not reveal any dental abnormalities but the left ramus and condyle of the mandible was found to be smaller than the right and to have a less well developed gonial angle. MR imagings of facial tissues showed that the masseter, temporalis and medial pterygoid muscles were grossly hypoplastic and the lateral pterigoid mildly so on the left side. The clinical findings thus suggested that this was not a typical case of a first and second branchial arch syndrome.
