Abstract
In order to build a criterion of facial morphology diagnosis, the authors previously proposed the facial form classification chart. This chart was clinically used to diagnose 176 cases of maxillofacial deformity in five institutions, and these were subjected to a statistical study. The results were as follows:
1) Facial morphology diagnoses given to 176 cases aggregated 283. The most common diagnosis was mandibular prognathism (123/176, 70%), followed by facial asymmetry (66/176, 38.0%), and maxillary retrognathism (38/176, 21.6%).
2) Ninety cases (90/176, 51.1%) were given a single diagnosis and 86 (86/176, 48.9%) were given multiple diagnoses. Mandibular prognathism only was most common (56/176, 31.8%), followed by mandibular prognathism with maxillary retrognathism (33/176, 18.8%), mandibular prognathism with facial asymmetry (29/176, 16.5%), facial asymmetry single (19/176, 10.8%) and so on.
3) The facial form classification chart was empirically assumed to systematize a common proress of facial morphology diagnosis, and offers a guide line that could standardize diagnosis of maxillofacial deformities.
