Evaluación perceptual de la insuficiencia velofaríngea en personas con fisura del paladar: una revisión integradora de literatura / Perceptual evaluation of velopharyngeal insufficiency in people with cleft palate: an integrative literature review

La insuficiencia velofaríngea (IVF) secundaria de fisura del paladar corresponde al cierre incompleto del mecanismo velofaríngeo durante el habla, debido a una falta de tejido en el paladar blando o las paredes de la faringe, lo cual genera una resonancia hipernasal y una emisión nasal de aire en los sonidos orales. Al respecto, en la literatura existen diversas propuestas para la evaluación perceptual de la IVF. Por esto, el objetivo del presente estudio es describir la evaluación perceptiva auditiva de la insuficiencia velofaríngea, mediante una revisión integradora de literatura. Para ello, en mayo de 2020 las bases de datos electrónicas PUBMED, LILACS, SciELO y Cochrane, fueron consultadas utilizando las palabras claves en inglés: "Velopharyngeal Sphincter", "Velopharyngeal Insufficiency", "Cleft Palate", "Speech Intelligibility", "Speech Production Measurement", "Speech Articulation Tests" y "Speech-Language Pathology" y sus respectivos equivalentes en portugués y español. Se seleccionaron artículos originales relacionados al tema, y se creó un protocolo específico para la extracción de los datos. En total se encontraron 2.385 artículos. De ellos, 2.354 fueron excluidos por el título, 13 por el resumen y 3 luego de la lectura del texto completo. Finalmente, a partir de la metodología desarrollada, en esta revisión fueron utilizados 33 artículos. A partir de la revisión realizada se concluye que los parámetros más utilizados en la evaluación son la hipernasalidad, la emisión nasal y la articulación compensatoria asociada a IVF. Estos parámetros son evaluados principalmente en oraciones, habla espontánea y palabras, por un fonoaudiólogo experto, en vivo y mediante grabaciones de audio.

Secondary Velopharyngeal insufficiency (VPI) to cleft palate corresponds to the incomplete closure of the velopharyngeal mechanism during speech, due to lack of tissue in the soft palate or the walls of the pharynx, which generates a hypernasal resonance and nasal air emission in oral sounds. In this regard, there are various proposals in the literature for the perceptual evaluation of VPI. For this reason, the objective of the present study is to describe the auditory perceptual evaluation of velopharyngeal insufficiency, through an integrative literature review. To this end, in May 2020 the electronic databases PUBMED, LILACS, SciELO and Cochrane were consulted using the key words in English: "Velopharyngeal Sphincter", "Velopharyngeal Insufficiency", "Cleft Palate", "Speech Intelligibility", "Speech Production Measurement", "Speech Articulation Tests" and "Speech-Language Pathology", and their equivalent properties in Portuguese and Spanish. Original articles related to the topic were selected, and a specific protocol for data extraction was created. In total, 2,385 articles were found. Of these, 2,354 were excluded due to the title, 13 due to the abstract and 3 after reading the full text. Finally, based on the methodology developed, 33 articles were used in this review. From the review carried out, it is concluded that the parameters most used in the evaluation are hypernasality, nasal emission and the compensatory joint associated with IVF. These parameters are evaluated mainly in sentences, spontaneous speech and words, by an expert speech therapist, live and through audio recordings.

Voz hipernasal y regurgitación nasal aguda: reporte de un caso clínico y revisión de la literatura / Hypernasal speech and acute nasal regurgitation: a case report and a review of the literature

RESUMEN La voz hipernasal y la regurgitación nasal son síntomas de disfunción velofaríngea. Ésta puede tener múltiples causas: anatómicas, neurológicas o funcionales. Se describe el caso de una paciente de sexo femenino, de 13 años, que se presenta con voz hipernasal y regurgitación nasal aguda. Al examen físico se evidencia inmovilidad del velo del paladar derecho sin otros hallazgos neurológicos. El estudio con resonancia nuclear magnética de cerebro y punción lumbar fueron normales. Se diagnosticó una incompetencia velofaríngea aguda transitoria, de probable etiología viral. La paciente evolucionó de forma favorable con mejoría clínica progresiva. La incompetencia velofaríngea a causa de una paresia o parálisis del nervio vago y/o nervio glosofaríngeo es una causa poco frecuente de disfunción velofaríngea.

ABSTRACT Hypernasal speech and nasal regurgitation are symptoms of velopharyngeal dysfunction. This may have multiple causes, including velopharyngeal incompetence due to paresis or paralysis of the vagus nerve and/or glossopharyngeal nerve. We describe the case of a 13 year-old female patient, with hypernasal speech and acute nasal regurgitation, with a physical examination showing immobility of the right palate with no other neurological findings. Magnetic resonance imaging of the brain and lumbar puncture was normal. Transient acute velopharyngeal incompetence was diagnosed, probably of viral etiology. The patient evolved favorably with progressive clinical improvement. Velopharyngeal incompetence due to paresis or paralysis of the vagus and/or glossopharyngeal nerves is a rare cause of velopharyngeal dysfunction.

Avaliação do efeito imediato de exercício de trato vocal semiocluído no mecanismo velofaríngeo em cinco portadores de fissura labiopalatina: estudo piloto / Assessment of the immediate effect of a semi-occluded vocal tract exercise on velopharyngeal mechanism in five patients with cleft lip and palate: pilot study

Introdução: As fissuras labiopalatinas não sindrômicas estão incluídas entre as malformações craniofaciais severas mais frequentes na população humana. O indivíduo acometido pode apresentar alterações no mecanismo velofaríngeo, comprometendo-se assim a inteligibilidade da fala. O objetivo deste estudo foi analisar o efeito imediato do exercício de trato vocal semiocluído no mecanismo velofaríngeo de pacientes com fissura labiopalatina. Métodos: A amostra foi composta por cinco sujeitos com fissura labiopalatina reparada cirurgicamente submetidos a avaliação multidimensional, de videonasofibroscopia, análise das imagens dinâmicas por meio de software especializado e análise de fala por meio da avaliação perceptivoauditiva e parecer autorreferido. Resultados: Todos os pacientes apresentaram melhora na fala encadeada após o exercício, melhora acentuada na impressão geral da emissão e projeção vocal, maior fechamento velofaríngeo e efeito positivo na autoavaliação. Conclusão: Observou-se efeito positivo do exercício de trato vocal semiocluído quando aplicado nessa amostra.

Effect of Vocal Fry on Voice and on Velopharyngeal Sphincter

Abstract Introduction It is known that the basal sound promotes shortening and adduction of the vocal folds and leaves the mucosa looser. However there are few studies that address the supralaryngeal physiological findings obtained using the technique. Objective To check the effectiveness of using vocal fry on the voice and velopharingeal port closure of five adult subjects, whose cleft palate has been corrected with surgery. Methods Case study with five subjects who underwent otolaryngology examination by means of nasopharyngoscopy for imaging and measurement of the region of velopharyngeal port closure before and after using the vocal fry technique for three minutes. During the exam, the subjects sustained the isolated vowel /a:/ in their usual pitch and loudness. The emission of the vowel /a:/ was also used for perceptual analysis and spectrographic evaluation of their voices. Results Four subjects had an improvement in the region of velopharyngeal port closure; the results of the spectrographic evaluation were indicative of decreased hypernasality, and the results of the auditory-perceptual analysis suggested improved overall vocal quality, adequacy of loudness, decreased hypernasality, improvement of type of voice and decreased hoarseness. Conclusion This study showed a positive effect of vocal fry on voice and greater velopharyngeal port closure.

Ressonância de fala e complicações cirúrgicas após palatoplastia primária com veloplastia intravelar em pacientes com fissura de lábio e palato / Speech resonance and surgical complications after primary palatoplasty with intravelar veloplasty in patients with cleft lip and palate

INTRODUÇÃO: A correção cirúrgica primária do palato é de fundamental importância na reabilitação do indivíduo com fissura labiopalatina e visa tanto a restauração anatômica local, com o fechamento da comunicação existente entre a cavidade nasal e oral, como a restauração funcional do anel velofaríngeo por meio do reposicionamento dos músculos palatinos. Ao longo dos anos, as técnicas de fechamento de palato foram evoluindo progressivamente, utilizando, cada vez mais, o procedimento de reposicionamento da musculatura responsável pelo fechamento do esfíncter velofaríngeo, denominado veloplastia intravelar. Tal procedimento favorece o funcionamento sinérgico da musculatura velar e faríngea, evitando, assim, os sintomas decorrentes da insuficiência velofaríngea. No entanto, apesar de todos os esforços no sentido de conseguir o funcionamento velofaríngeo adequado, intercorrências intraoperatórias e complicações pós-operatórias imediatas e/ou tardias podem contribuir para o insucesso da palatoplastia primária e, consequentemente, levar ao aparecimento de hipernasalidade. MÉTODOS: Sessenta pacientes submetidos à palatoplastia primária com veloplastia intravelar. Intercorrências intraoperatórias e complicações pós-operatórias imediatas e tardias foram investigadas. A presença e localização de fístula ou deiscência do palato foi feita por meio de avaliação clínica. Os pacientes foram submetidos, também, à gravação em áudio de amostra de fala, as quais foram analisadas por três fonoaudiólogas. As intercorrências intraoperatórias e as complicações pós-operatórias foram analisadas de forma descritiva. A associação entre as intercorrências intraoperatórias e complicações imediatas e tardias com a formação de fístulas, bem como a associação entre a ocorrência de fístulas e deiscências com a presença e ausência de hipernasalidade, foram analisadas por meio de Teste de Fisher. RESULTADOS: Verificou-se 5% de intercorrências intraoperatórias, 20% de complicações imediatas e 13,3% de complicações tardias. O índice de fístulas foi de 16,67%. A proporção de hipernasalidade foi de 18,6%. CONCLUSÃO: A palatoplastia com veloplastia intravelar utilizada no presente estudo demonstrou ser uma técnica segura, de fácil execução, eficiente para a fala e com baixos índices de complicações.

INTRODUCTION: The primary surgical correction of the palate is of fundamental importance in the rehabilitation of individuals with labiopalatine cleft and aims for local anatomical restoration and closure of the existing communication between the nasal and oral cavities, such as functional restoration of the velopharyngeal ring through repositioning of the palatine muscles. Palate closure techniques have evolved progressively over the years and increasingly involve repositioning of the muscles responsible for closing the velopharyngeal sphincter, called intravelar veloplasty. This procedure encourages the synergistic operation of the velar and pharyngeal musculature, thereby avoiding the symptoms resulting from velopharyngeal insufficiency. However, despite efforts to achieve adequate velopharyngeal function, intraoperative events and immediate postoperative and/or late complications may contribute to primary palatoplasty failure and consequently lead to hypernasality. METHODS: Sixty patients underwent primary palatoplasty with intravelar veloplasty. Intraoperative events and immediate and late postoperative complications were investigated. The presence and location of palatal fistula or dehiscence was assessed by clinical evaluation. The patients also made an audio recording of their speech that was analyzed by three speech therapists. The intraoperative events and postoperative complications were descriptively analyzed. The association between intraoperative events and immediate and late postoperative complications with the formation of fistulae as well as that between the occurrence of fistulae and dehiscences and the presence and absence of hypernasality was analyzed using Fisher's exact test. RESULTS: Overall, there was a 5% incidence of intraoperative events, 20% incidence of immediate complications, and 13.3% incidence of late complications. Fistulae and hypernasality were found in 16.67% and 18.6% of cases, respectively. CONCLUSION: Palatoplasty with intravelar veloplasty is a safe and easily implemented technique that is efficient for speech and has low complication rates.

Rinoglotalfilia como estratégia renunciativa na interlocução de uma criança com nasalidade excessiva e sua terapeuta / Rhinoglotalphilia as an enunciative strategy in the interlocution between a child with excessive nasality and her speech therapy professional / Rinoglotalfilia como una estratégia enunciativa en la interlocuión entre una niña com nasalidade excesiva y su terapeuta

Este texto apresenta e desenvolve a hipótese de que a afinidade entre o traço nasal e o envolvimento articulatório da glote na linguagem de falantes com nasalidade excessiva é um efeito da necessidade de prover pistas acústicas ao interlocutor. Analisam-se, com base em uma leitura ampliada da teoria da enunciação de Émile Benveniste, dados de linguagem de uma criança de quatro anos de idade com incompetência velofaríngea por paresia motora, coletados em situação de clínica fonoaudiológica. Utiliza-se metodologia qualitativa para a análise dos diálogos coletados. Os resultados demonstram uma relação entre a dificuldade interpretativa do interlocutor e intensificação da rinoglotalfilia na fala da menina.

This paper shows and analyzes the hypothesis that the affinity between nasal constraint and glotal articulation in speekers with excessive nasality is a consequence of the need to give acoustical cues to the interlocutor. The language data of a four years old child with velopharingeal incompetence by motor paresy, collected in clinical speech therapy situation, are analysed by an ampliated approach of Émile Benveniste theory. A qualitative method was utilized for the analasys. The results show the relationship between the interlocutor interpretation limitations and rhinoglotalphilia intensification in the girls speech.

Este texto presenta y desarrolla la hipótesis de que la afinidad entre el rasgo nasal y la participación de la glotis en el lenguaje de hablantes con nasalidad excesiva es un efecto de la necesidad de proporcinar señales acústicas al interlocutor. Se analizan, con base en una lectura ampliada de la teoria de la enunciación de Émile Benveniste, datos de una niña de 4 años con incompetencia velofaríngea por paresia motora, recogidos en situacion de clinica fonoaudiologica. El metodo de la analise de los datos coletados es qualitativo. Los resultados demuestran una relación entre la dificultad interpretativa del interlocutor y la intensificacionción de la rinoglotalfilia en el habla de la niña.

Velopharyngeal dysfunction: a systematic review of major instrumental and auditory-perceptual assessments

Velopharyngeal dysfunction may cause impaired verbal communication skills in individuals with cleft lip and palate; thus, patients with this disorder need to undergo both instrumental and auditory-perceptual assessments. OBJECTIVE: To investigate the main methods used to evaluate velopharyngeal function in individuals with cleft lip and palate and to determine whether there is an association between videonasoendoscopy results and auditory-perceptual assessments. METHOD: We conducted a systematic review of the literature on instrumental and auditory-perceptual assessments. We searched the PubMed, Medline, Lilacs, Cochrane, and SciELO databases from October to November 2012. SUMMARY OF FINDINGS : We found 1,300 studies about the topic of interest published between 1990 and 2012. Of these, 56 studies focused on velopharyngeal physiology; 29 studies presented data on velopharyngeal physiology using at least 1 instrumental assessment and/or 1 auditory-perceptual assessment, and 12 studies associated the results of both types of assessments. Only 3 studies described in detail the analysis of both methods of evaluating velopharyngeal function; however, associations between these findings were not analyzed. CONCLUSION: We found few studies clearly addressing the criteria chosen to investigate velopharyngeal dysfunction and associations between videonasoendoscopy results and auditory-perceptual assessments...

Comparison of videonasoendoscopy and auditory-perceptual evaluation of speech in individuals with cleft lip/palate

The velopharyngeal sphincter (VPS) is a muscle belt located between the oropharynx and the nasopharynx. Investigations of velopharyngeal function should include an auditory-perceptual evaluation and at least 1 instrument-based evaluation such as videonasoendoscopy. AIM: To compare the findings of auditory-perceptual evaluation (hypernasality) and videonasoendoscopy (gap size) in individuals with cleft lip/palate. METHOD: This was a retrospective, cross-sectional study assessing 49 subjects, of both sexes, with cleft lip/palate followed up at the Otorhinolaryngology Service and the Speech Therapy outpatient clinic of Hospital de Clínicas de Porto Alegre (HCPA). The results from the auditory-perceptual evaluation and the videonasoendoscopy test were compared with respect to the VPS gap size. RESULTS: Subjects with moderate/severe hypernasality had more severe velopharyngeal closure impairment than those with a less severe condition. The interaction between hypernasality severity and the presence of other speech disorders (p = 0.035), whether compensatory and/or obligatory, increased the likelihood of having a moderate-to-large gap in the velopharyngeal closure. CONCLUSIONS: We observed an association between the findings of these 2 evaluation methods...

Fissura palatina reparada: fechamento velofaríngeo antes e durante o som basal / Cleft palate repair: velopharyngeal closure before and during the basal tone

Portadores de fissura palatina apresentam inadequado fechamento velofaríngeo (FVF), com consequente hipernasalidade vocal que pode ser diminuída com o som basal. OBJETIVO: Comparar o FVF durante a realização do som basal com a emissão em registro modal, em pacientes com fissura palatina pós-forame reparada. MATERIAIS E MÉTODOS: Estudo de Casos com quatro homens adultos, portadores de fissura palatina pós-forame reparada. Imagens do FVF por nasofaringoscopia, durante a emissão da vogal [a] em registro modal e basal. Julgamento das imagens realizado por quatro otorrinolaringologistas. RESULTADOS: Em três sujeitos, não houve mudança no tipo de FVF entre os registros analisados; as modificações que ocorreram na maioria dos sujeitos referem-se apenas ao grau de movimentação das estruturas envolvidas, pois, em registro basal, o movimento das paredes laterais da faringe se manteve, o movimento da parede posterior da faringe estabilizou, o movimento do véu palatino diminuiu discretamente, e a Prega de Passavant se evidenciou. CONCLUSÕES: O tipo de FVF se manteve em três dos quatro sujeitos analisados, quando comparado o registro modal com o basal, havendo modificações no grau da movimentação das estruturas envolvidas, evidenciando a Prega de Passavant.

Patients with palatine fissure have inadequate velopharyngeal closure (VPC), with consequent vocal hypernasality which can be reduced by a basal tone. AIM: to compare VPC during a basal tone with the emission of a modal recording, in patients with repaired post-foramen palatine fissure. MATERIALS AND METHODS: case study with four adult men, all with repaired post-foramen palatine fissure. VPC images through nasal-pharyngoscopy during the emission o f the [a] vowel in a modal and basal recording. The images were studied by four ENTs. RESULTS: in three subjects there was no change in the type of VPC considering the recordings analyzed; the changes which happened to most of the subjects are associated only to the degree of movement of the structures involved, since in the basal recording the movement of the laryngeal lateral walls was kept, the movement of the posterior pharyngeal wall stabilized, the movement of the palatine veil was mildly reduced, and the Passavant fold was evident. CONCLUSIONS: The type of VPC was kept in the four subjects analyzed, when we compared the modal and basal recordings, there was a modification in the degree of movements in the structures involved, making it clear the Passavant Fold.
