Refinement in aesthetic contouring of the prominent mandibular angle.

Oriental women, in general, greatly desire a more delicate and feminine facial shape. This can be obtained by contouring the prominent mandibular angles that give a strong, masculine image. Western authors regarded masseteric muscular hypertrophy the main cause of a square facial appearance, so they usually corrected it by partially excising the masseter muscle. In the authors' view, a square facial appearance in the Oriental is not due to masseteric hypertrophy but to a posterior projection and lateral flaring of the mandibular angle. However, it is sometimes difficult to make the square face narrow and ovoid by using only the conventional curved-angle osteotomy. We divided patients, whose chief complaint was a square facial appearance, into three groups after clinical, photographic, and radiographic evaluation. We applied different contouring methods to each of the three groups and obtained cosmetically improved facial appearance in both lateral and frontal views.
