Functional gains measured by MBGR and impact on quality of life in subject submitted to orthognathic surgery: case report

The proposed theme is Speech Therapy Intervention before and after orthognathic surgery. Evaluation (through MBGR Protocol of Orofacial Myofunctional Evaluation with scores) and speech therapy intervention were performed in the preoperative (three months) and postoperative periods, started on the 20th day (for three months) after the surgeon's liberation. In addition, it was investigated the impact of dentofacial deformity in the patient's life quality through the Oral Health Impact Profile - reduced version. In the preoperative evaluation, Simultaneous bilateral chewing, presence of noise in the temporomandibular joint and unsystematic lip closure were found while performing the function. During swallowing, there was contraction of the perioral muscles and presence of residues after this function. It was found, in speech, distortion in the /r/ sound. There was pain on palpation in the masticatory muscles and decreased tone in the perioral and masticatory muscles. It was found high impact on quality of life, totaling 32 points. In the evaluation after speech therapy intervention, improvement was observed in the chewing functions (pre: 4 points, post: 1 point), swallowing (pre: 14, post: 5), breathing (pre: 3, post: 1) and speech (pre: 7, post: 1), muscle mobility (pre: 8, post: 1), tonicity of the muscles (pre: 5, post: 0) and pain on palpation (pre: 10, post: 2). There was improvement in the posture of the lips and significant improvement in quality of life, from 32 to 8 points. It was found an improvement in the physiology of the stomatognathic functions, decreased pain on palpation, balance in tone, muscle mobility and improved quality of life.
