摘要
OBJECTIVES. The aim of the present study was to analyse the anatomical three-dimensional characteristics of masseter muscle in growing subjects by using an ultrasound method.MATERIALS AND METHODS. The sample comprised 60 prepubescent subjects. According to the facial divergence (Frankfort-Mandibular plane Angle, FMA) the subjects were divided into three groups with different underlying vertical facial patterns: brachyfacial, FMA <22 degrees; mesofacial, 22 degrees <= FMA <= 28 degrees; dolichofacial, FMA > 28 degrees. an ultrasound scan was carried out in order to analyse the masseter muscle's width, thickness, cross-sectional area and volume.RESULTS. Measurements of the whole masseter in dolichofacial patients were significantly smaller when compared with brachyfacial and mesofacial individuals.CONCLUSIONS. A significant negative correlation was found between the ultrasound measurements and the divergence (FMA).
