Speech therapy in peripheral facial palsy: an orofacial myofunctional approach

Abstract

Objective: To delineate the contributions of speech therapy in the rehabilitation of peripheral facial palsy, describing the role of orofacial myofunctional approach in this process. Methods: A literature review of published articles since 1995, held from March to December 2008, based on the characterization of peripheral facial palsy and its relation with speechlanguage disorders related to orofacial disorders in mobility, speech and chewing, among others. The review prioritized scientific journal articles and specific chapters from the studied period. As inclusion criteria, the literature should contain data on peripheral facial palsy, quotes on the changes in the stomatognathic system and on orofacial miofunctional approach. We excluded studies that addressed central paralysis, congenital palsy and those of non idiopathic causes. Results: The literature has addressed the contribution of speech therapy in the rehabilitation of facial symmetry, with improvement in the retention of liquids and soft foods during chewing and swallowing. The orofacial myofunctional approach contextualized the role of speech therapy in the improvement of the coordination of speech articulation and in the gain of oral control during chewing and swallowing Conclusion: Speech therapy in peripheral facial palsy contributed and was outlined by applying the orofacial myofunctional approach in the reestablishment of facial symmetry, from the work directed to the functions of the stomatognathic system, including oralfacial exercises and training of chewing in association with the training of the joint. There is a need for a greater number of publications in this specific area for speech therapy professional.
