Abstract

The purpose of this study was to clarify the facial skeletal characteristics of patients with masticatory muscle tendon-aponeurosis hyperplasia. We traced the cephalometric radiographs of 10 adult female patients and made 10 linear measurements and 8 angler measurements. The control group was the cephalometric norm for Japanese adult females (n=50). The difference of each parameter between the patient group and the control group was statistically analyzed using the unpaired t test.
As a result, ANS-Me, Is-Is', Mand. Pl. to SN, Occ. Pl. to SN and Gonial Angle of the patient group were significantly low, and Pog'-Go and Ramus Pl. to SN were significantly high compared with those of the control group. The patient group was divided into three facial skeletal types. All three types showed a square mandible.
