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.
