ABSTRACT
Objective:
to describe the chewing and swallowing pattern of obese individuals indicated for bariatric surgery/gastroplasty before the procedure, using standardized clinical protocols.
Methods:
a cross-sectional descriptive case-control study that presents preliminary data for a larger investigation. Eight participants matched for age and sex were divided into two groups (four in the research group and four as controls) and submitted to clinical speech therapy assessment using the “Questionnaire on eating behavior and the anatomofunctional conditions of the stomatognathic system” from the Expanded Protocol of Orofacial Myofunctional Evaluation with Scores (OMES-E) and the maximum tongue pressure test.
Results:
when compared to controls, participants from the research group exhibited a predominantly unilateral chewing preference; reported that they just “swallowed food”; repeated swallowing of liquid and solid foods, with facial muscle tension; increased cheek volume and the presence of flaccidity; shorter meal and chewing times; increased tension of the lips, mentalis and facial muscles at rest and during swallowing; predominance of insufficient ability with associated movements and/or tremors during lip, tongue, jaw and cheek movements; and lack of knowledge regarding speech therapy.
Conclusion:
orofacial myofunctional dysfunctions were more frequent in patients from the research group when compared to controls. A need to increase the number of participants in this case series and conduct a post-surgery reassessment, in order to provide a longitudinal description of the chewing and swallowing pattern, was verified.
