Title in Portuguese
Fala em indivíduos com fissura labiopalatina após a palatoplastia primária pelas técnicas de Furlow e von Langenbeck
Keywords in Portuguese
Avaliação
Fala
Fissura palatina
Insuficiência velofaríngea
Abstract in Portuguese
Introdução: A palatoplastia primária para correção da fissura palatina tem a finalidade de reparar anatômica e funcionalmente o palato, a fim de permitir o funcionamento adequado do mecanismo velofaríngeo para a aquisição de fala. Porém, mesmo após a realização da palatoplastia, 20% dos pacientes, em média, podem apresentar disfunção velofaríngea, e como principal indicador da significância clínica dos sintomas de fala tem-se a avaliação perceptivo-auditiva da fala. Atualmente, há um consenso de que o protocolo para o reparo cirúrgico do palato é crucial para o desenvolvimento da fala normal e do crescimento da face a longo prazo. Objetivo: O presente trabalho tem como objetivo comparar resultados de fala de pacientes com fissura unilateral de lábio e palato que foram submetidos à palatoplastia primária, ou pela técnica de Furlow (F) ou pela de von Langenbeck (vL). Material e Métodos: A casuística deste estudo foi constituída por 466 pacientes com fissura labiopalatina unilateral, em que 211 foram submetidos à palatoplastia primária pela técnica de F e 255 pela de vL, entre 9 e 18 meses de idade, por quatro cirurgiões. Foram coletados do Protocolo de Avaliação Fonoarticulatória contido no prontuário dos pacientes, os resultados do Teste de Emissão de Ar Nasal, do Teste de Hipernasalidade, do julgamento perceptivo-auditivo da nasalidade de fala e da avaliação da ocorrência (presença/ausência) e do tipo de articulação compensatória, referentes à última avaliação de fala que o paciente foi submetido no HRAC/USP. Resultados: Quanto à comparação das medidas entre as técnicas cirúrgicas (F vs. vL) nenhum resultado foi estatisticamente significante (p>0,05), exceto o julgamento perceptivo-auditivo da nasalidade, referente à hipernasalidade moderada (p<0,05). Conclusão: A hipótese de que os resultados de fala de pacientes operados pela técnica de Furlow fosse superior aos dos operados pela de von Langenbeck não se confirmou. Portanto, conclui-se que as técnicas cirúrgicas utilizadas na palatoplastia primária não foram relevantes para determinar diferença nos resultados de fala.

Speech in individuals with cleft lip and palate after primary palatoplasty techniques by Furlow and von Langenbeck

Velopharyngeal insufficiency
Abstract in English
Introduction: The primary palatoplasty to correct cleft lip and palate aims to repair the palate anatomically and functionally, to allow the proper functioning of the velopharyngeal mechanism for the acquisition of speech. However, even after the palatoplasty, 20% of the patients in average can present velopharyngeal dysfunction. Perceptual assessment of speech is the primary indicator of clinical significance of the speech symptoms. Today there is a general consensus that the protocol for surgical repair of the palate is crucial for the development of normal speech and facial growth in long term. Objective: This study aims to compare the speech results of patients with unilateral cleft lip and palate who underwent primary palatoplasty, either by the Furlow (F) or by the von Langenbeck (vL) techniques. Material and Methods: The sample of this study was composed of 466 patients with unilateral cleft lip and palate. Out of the total sample, 211 were submitted to primary palatoplasty by the F technique and 255 by the vL, between 9 and 18 months of age, by four surgeons. Data were collected from the Articulatory Assessment Protocol contained in the medical records of patients, with regard to the results of the Test of Nasal Air Emission, Test of Hypernasality, auditory perception judgment of speech nasality, and assessment of occurrence (presence/absence) and the type of compensatory articulation, referring to the last speech evaluation the patient was submitted at the HRAC/USP. Results: None of the compared results between surgical techniques (F vs. vL) was statistically significant (p>0.05), except the auditory perception of nasality judgment, with regard to moderate hypernasality (p<0.05). Conclusion: The hypothesis that the speech outcomes of patients operated by Furlow technique were higher than those operated by the von Langenbeck was not confirmed. Therefore, it is concluded that the surgical techniques used in primary palatoplasty were not relevant to determine differences in the results of speech
