A relação do volume do corpo adiposo de bichat com a motricidade do sistema estomatognático

Abstract

This study verified the relationship between Bichat Adipose Body volume and stomatognathic system myomotricity. Bichat Fat Body is a fat mass located on the cheek. We analyzed a group of 20 individuals, 13 women and 7 men, who underwent cheek ultrasound, using a specific protocol, where it was possible to estimate the volume of the Bichat Adipose Body. The same operator took two images on either side of the cheek. The first image referred to the deep portion of the fat (main body) and the second image to the anterior portion (buccal extension). In both images were taken the dimensions of larger diameter and two others in a perpendicular position to the first, estimating the volume through three orthogonal planes. At the same time, the myomotricity of the stomatognathic system was evaluated using the Myofunctional Score Assessment protocol, applied by a qualified speech therapist who verified the motor conditions related to swallowing, chewing, speech and breathing, as well as facial anatomical characteristics. This assessment gave rise to a Total Result of the Myofunctional Score Assessment protocol ranging from 0 to 100 (0 corresponds to the worst functional status and 100 to the best functional condition). From these data we analyzed the statistical relationship of the Total Result with the fat volumes found. The data did not show large variations among themselves. Dispersion analysis found no association intensity. Thus, the ratio of fat volume on both the right and left sides was not related to the total result of the protocol used. When the relationship of each item of the Myofunctional Score Assessment protocol with Bichat Adipose Body volumes was compared separately, a significant relationship was found between this volume and the change in mandibular posture during chewing.
