Speech therapy and orthognathic surgery: a literature review

Introduction: Dentofacial deformities are associated with changes in dental occlusion, which may cause changes in the myofunctional system according to the type of disproportion. These deformities can cause changes and/or adaptations in the stomatognathic system. The objective of this study was to identify the relationship between speech therapy and orthognathic surgery based on refereed publications. Method: A bibliographic survey was conducted without considering a specific publication period in the databases, PubMed, SciELO and BVS. Results: Fifteen articles were critically evaluated with respect to the type of study, objectives, number and sex of participants, methodology, results and conclusions. Based on their aims, the articles were grouped into 1) speech-therapy group (STG); 2) changes group (CG); 3) techniques group (GT) and 4) others group (OG). Conclusion: There is little information regarding direct speech therapy intervention, and the majority of the studies were directed to the aesthetic and functional changes in the hard and soft tissue in patients who underwent orthognathic surgery. Some studies addressed methods and/or specific examination procedures to verify the changes in the soft and hard tissues of the facial profile of patients who underwent orthognathic surgery, and a study detailed the profile of individuals who underwent treatment for dentofacial deformity and apnea-hypopnea syndrome

Speech profile of patients undergoing primary palatoplasty

Objetivo: caracterizar o perfil e a fala de pacientes submetidos à palatoplastia primária em um hospital escola de São Paulo, levando-se em consideração a idade do paciente no momento da cirurgia (precoce até os 2 anos de idade e tardio após 2 anos). Método 97 indivíduos, de ambos os gêneros, com diagnóstico de fissura de palato associada ou não à de lábio, divididos em dois grupos: 1) grupo precoce (GP), composto por 43 indivíduos operados até o segundo ano de vida; 2) grupo tardio (GT), composto por 54 indivíduos operados após o segundo ano. Os participantes foram submetidos à avaliação clínica fonoaudiológica. Os parâmetros avaliados e considerados para o estudo foram: classificação da ressonância, presença de ronco nasal audível, ocorrência de fraca pressão intraoral, ocorrência de emissão nasal, classificação da inteligibilidade de fala e presença de distúrbios articulatórios compensatórios (DACs). Uma porcentagem randomicamente selecionada de participantes (30%) foi reavaliada por mais duas fonoaudiólogas e a comparação entre os juízes indicou alta concordância. Resultados (nível de significância de 5%): os grupos não se diferenciaram em relação à classificação da ressonância (p=0,067), grau de hipernasalidade (p=0,113), presença de ronco nasal (p=0,179), ocorrência de fraca pressão intraoral (p=0,152), ocorrência de emissão nasal (p=0,369) e classificação da inteligibilidade de fala (p=0,113). Em relação à presença de DACs, os grupos se diferenciaram (p=0,020), com maior ocorrência de fonemas alterados no GT. Conclusão foi possível caracterizar o perfil geral e de fala dos pacientes submetidos à palatoplastia primária do referido hospital escola. Concluiu-se que a realização da cirurgia precocemente traz melhores resultados em relação à fala.Purpose: to characterize the profile and speech characteristics of patients undergoing primary palatoplasty in a Brazilian university hospital, considering the time of intervention (early, before two years of age; late, after two years of age). Methods Participants were 97 patients of both genders with cleft palate and/or cleft and lip palate, assigned to the Speech-language Pathology Department, who had been submitted to primary palatoplasty and presented no prior history of speech-language therapy. Patients were divided into two groups: early intervention group (EIG) – 43 patients undergoing primary palatoplasty before 2 years of age and late intervention group (LIG) – 54 patients undergoing primary palatoplasty after 2 years of age. All patients underwent speech-language pathology assessment. The following parameters were assessed: resonance classification, presence of nasal turbulence, presence of weak intraoral air pressure, presence of audible nasal air emission, speech understandability, and compensatory articulation disorder (CAD). Results At statistical significance level of 5% (p≤0.05), no significant difference was observed between the groups in the following parameters: resonance classification (p=0.067); level of hypernasality (p=0.113), presence of nasal turbulence (p=0.179); presence of weak intraoral air pressure (p=0.152); presence of nasal air emission (p=0.369), and speech understandability (p=0.113). The groups differed with respect to presence of compensatory articulation disorders (p=0.020), with the LIG presenting higher occurrence of altered phonemes. Conclusion It was possible to assess the general profile and speech characteristics of the study participants. Patients submitted to early primary palatoplasty present better speech profile

Orofacial myofunctional characterization in Parry-Romberg syndrome

Objetivo: Caracterizar os aspectos miofuncionais orofaciais de pacientes acometidos pela síndrome de Parry-Romberg, por meio de protocolos clínicos padronizados e da Eletromiografia de Superfície (EMGs) dos músculos mastigatórios. Métodos: A amostra foi composta por quatro pacientes com síndrome de Parry-Romberg e quatro indivíduos normais, separados em Grupo Pesquisa (GP) e Grupo Controle (GC), respectivamente, pareados por gênero e idade. Os grupos foram comparados em relação ao desempenho na avaliação clínica fonoaudiológica - Protocolo de Avaliação Miofuncional Orofacial com Escores Expandido (AMIOFE-E), registro das medidas de antropometria facial e de movimentos mandibulares e na avaliação instrumental - Eletromiografia de Superfície (EMGs) dos músculos mastigatórios. Para todas as comparações, foi utilizado o nível de significância de 5%. Resultados: Observou-se diferença significativa entre os grupos nas variáveis postura/posição e escore total do AMIOFE-E. Além disso, a análise das variáveis categóricas do AMIOFE-E indicou diferença significativa entre os grupos para palato - altura e largura - e comportamento da língua na deglutição e função mastigatória. A análise das medidas antropométricas indicou diferença significativa entre os grupos somente para e lateralidade mandibular à direita. Não foram observadas diferenças para os dados eletromiográficos. Conclusão: O presente estudo é o primeiro a avaliar o Sistema Miofuncional Orofacial de indivíduos acometidos pela síndrome de Parry-Romberg, por meio de protocolos padronizados. Os resultados indicam que esses indivíduos apresentam alterações, principalmente quanto à mobilidade mandibular e mobilidade de língua, na deglutição e na função de mastigação.Purpose: To characterize the orofacial miofunctional aspects of patients with Parry-Romberg syndrome, using standardized clinical protocols and Surface Electromyography (sEMG) of the masticatory muscles. Methods: Participants were four patients with Parry-Romberg syndro¬me and four healthy individuals, paired by age and gender, divided in two groups: Study Group (SG) and Control Group (CG), respectively. The groups were compared regarding performance during clinical examination - Orofacial Myofunctional Evaluation with Expanded Scores (OMES-E) and record of facial anthropometric measures and of jaw movements, and during an instrumental evaluation - Surface Elec¬tromyography (sEMG) of the masticatory muscles. Results: Statistically significant differences between the groups were observed for the follo¬wing variables: 1) numerical: mandibular lateral movement to the right, OMES-E posture/position and total score, 2) categorical: palate, behavior of the tongue during swallowing and chewing function. At sEMG no statistically significant differences were observed. Conclusion: The pre¬sent study is the first to evaluate the orofacial myofunctional system of individuals with Parry-Romberg syndrome using standardized protocols. Results indicate that these individuals present alterations specially when considering mandibular movements, tongue mobility during swallowing and chewing function

Adolescents with HIV and facial lipoatrophy: response to facial stimulation

OBJECTIVES: This study evaluated the effects of facial stimulation over the superficial muscles of the face in individuals with facial lipoatrophy associated with human immunodeficiency virus (HIV) and with no indication for treatment with polymethyl methacrylate. METHOD: The study sample comprised four adolescents of both genders ranging from 13 to 17 years in age. To participate in the study, the participants had to score six or less points on the Facial Lipoatrophy Index. The facial stimulation program used in our study consisted of 12 weekly 30-minute sessions during which individuals received therapy. The therapy consisted of intra- and extra-oral muscle contraction and stretching maneuvers of the zygomaticus major and minor and the masseter muscles. Pre- and post-treatment results were obtained using anthropometric static measurements of the face and the Facial Lipoatrophy Index. RESULTS: The results suggest that the therapeutic program effectively improved the volume of the buccinators. No significant differences were observed for the measurements of the medial portion of the face, the lateral portion of the face, the volume of the masseter muscle, or Facial Lipoatrophy Index scores. CONCLUSION: The results of our study suggest that facial maneuvers applied to the superficial muscles of the face of adolescents with facial lipoatrophy associated with HIV improved the facial area volume related to the buccinators muscles. We believe that our results will encourage future research with HIV patients, especially for patients who do not have the possibility of receiving an alternative aesthetic treatment

Clinical dysphagia risk predictors after prolonged orotracheal intubation

OBJECTIVES: To elucidate independent risk factors for dysphagia after prolonged orotracheal intubation. METHODS: The participants were 148 consecutive patients who underwent clinical bedside swallowing assessments from September 2009 to September 2011. All patients had received prolonged orotracheal intubations and were admitted to one of several intensive care units of a large Brazilian school hospital. The correlations between the conducted water swallow test results and dysphagia risk levels were analyzed for statistical significance. RESULTS: Of the 148 patients included in the study, 91 were male and 57 were female (mean age, 53.64 years). The univariate analysis results indicated that specific variables, including extraoral loss, multiple swallows, cervical auscultation, vocal quality, cough, choking, and other signs, were possible significant high-risk indicators of dysphagia onset. The multivariate analysis results indicated that cervical auscultation and coughing were independent predictive variables for high dysphagia risk. CONCLUSIONS: Patients displaying extraoral loss, multiple swallows, cervical auscultation, vocal quality, cough, choking and other signs should benefit from early swallowing evaluations. Additionally, early post-extubation dysfunction recognition is paramount in reducing the morbidity rate in this high-risk population

Electromyographic and ultrasonographic assessment of the masseter muscle in normal individuals: a pilot study

TEMA: estudos recentes utilizaram a ultrassonografia com o objetivo de medir cortes musculares. OBJETIVO: caracterizar o controle motor e a morfologia do músculo masseter em indivíduos normais, verificando a compatibilidade entre a eletromiografia de superfície e a ultrassonografia. MÉTODO: cinco indivíduos adultos, sem alterações no sistema estomatognático. Os procedimentos adotados para a avaliação dos participantes foram: 1. Eletromiografia de Superfície; 2. Ultrassonografia. RESULTADOS: houve alta correlação apenas para a comparação entre hemifaces direita e esquerda no exame de ultrassonografia (repouso 0,95; máxima intercuspidação dentária 0,86). CONCLUSÃO: os resultados indicam não haver correlação entre os métodos testados, sugerindo que os exames são complementares e não excludentes.BACKGROUND: recent studies have used ultrasonography with the purpose of measuring muscle cuts. AIM: to characterize the motor control and the morphology of the masseter muscle in normal individuals, verifying the compatibility between surface electromyography and ultrasonography. METHOD: five adult individuals, with no alterations of the stomatognathic system. The adopted assessment procedures for all participants were: 1. Surface Electromyography; 2. Ultrasonography. RESULTS: a high correlation was observed only when comparing both hemifaces in the ultrasonographic assessment (rest 0.95; biting 0.86). CONCLUSION: the results indicate that there is no correlation between the tested methods, suggesting that both methods are complementary and not mutually excludent

Mastigação e deglutição em indivíduos com obesidade indicados à realização de cirurgia bariátrica/gastroplastia - estudo piloto

Objetivo: descrever o padrão de mastigação e deglutição de indivíduos com obesidade, indicados à realização de cirurgia bariátrica/gastroplastia, antes do procedimento, por meio de protocolos clínicos padronizados. Métodos: trata-se de um estudo descritivo transversal, do tipo caso controle, que apresenta dados preliminares de um estudo maior. Oito participantes, divididos em quatro casos controle e quatro casos pesquisa, pareados por idade e gênero, foram submetidos a avaliação clínica fonoaudiológica por meio do “Questionário sobre comportamento alimentar e as condições anatomofuncionais do sistema estomatognático”, do protocolo AMIOFE-E e do teste de pressão máxima de língua. Resultados: os participantes dos casos pesquisa apresentaram em comparação aos casos controle: predominância de mastigação unilateral preferencial; referiram que apenas “engole o alimento”; repetição de deglutição em alimentos líquidos e sólidos, com presença de tensão dos músculos faciais; bochechas com volume aumentado e presença de flacidez; tempo de refeição e mastigação menores; tensão aumentada de lábios, músculos mentual e faciais no repouso e na deglutição; predominância de habilidade insuficiente com movimentos associados e/ou tremor nas tarefas de mobilidade de lábios, língua, mandíbula e bochechas; e desconhecimento da atuação fonoaudiológica. Conclusão: os pacientes do grupo pesquisa, apresentaram maior ocorrência de alterações miofuncionais orofaciais quando comparados ao grupo controle. Identifica-se a necessidade do aumento do número de participantes nesta série de casos, assim como a possibilidade de reavaliação no momento pós-cirúrgico visando uma descrição longitudinal do padrão de mastigação e deglutição.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
