ABSTRACT
Objective:
To study the differences of the superficial masseter muscle morphology characteristics between adult high-angle and low-angle facial skeletal types.Methods:
The subjects consisted of 37 yellow race adults,17 of them with high-angle facial skeletal type and 20 with low-angle. Ultrasound scanning was used to measure the perimeter, area, width, thickness, and length of masseter muscle. All the items were measured under relaxed, maximal clenching and maximal protrusive mandibular position.Results:
①In the various mandibular positions, the masseter muscle size of adults with high-angle facial skeletal type was smaller than that of those with low-angle.②Except for the changes of width from the relaxed to maximal clenching position and from the relaxed to maximal protrusive position(P0.05).③Stature and weight influenced the size of the masseter muscle.Conclusion:
The masseter muscle size of adult with high-angle facial skeletal type is smaller than that of those with low-angle.
