[Ultrasound anatomy of masticatory muscles. (Experimental and clinical study)].

Purpose: To describe the ultrasound anatomy of the masticatory muscles based on a comparison of the results of macroscopic and ultrasound studies of the masticatory muscles in vitro.

Material And Methods: In the experimental part, a macropreparation of the masticatory muscle was studied; in a clinical example, an ultrasound of the masticatory muscles was performed on a patient with normal occlusion using the author's methods for analyzing echograms.

Results: The ultrasound anatomy of the masticatory muscles is described based on a comparison of data from the study of a macroscopic specimen and ultrasound images of the masticatory muscle of an experimental animal.

[Ultrasound structural assessment of masseter muscles in subjects with different types of craniofacial growth].

The Aim Of The Study: Was to assess the correlation of various maxillofacial structures in subjects with different types of craniofacial growth.

Materials And Methods: The results of comparing the morphology of the masseter muscles (thickness, area, echostructure) in 30 volunteers aged from 18 to 25 years without malocclusions and different type of craniofacial growth were presented.

Results: A significant correlation between the thickness of the masseter muscles and morphology of the facial skull was observed: the smallest thickness of masseter muscles was in subjects with vertical type of craniofacial growth, the largest - in patients with horizontal type of craniofacial growth.
