Assessment of Grade of Dysphonia and Correlation With Quality of Life Protocol.

OBJECTIVE: The main objective of this study is to check the correlation between vocal self-assessment and results of the Voice-Related Quality of Life (V-RQOL) protocol, and whether there is a correlation between perceptual vocal assessment made by voice therapists and the results from the V-RQOL protocol. STUDY DESIGN: The study included 245 subjects with vocal complaints. This was a prospective analytical clinical study. METHODS: Vocal perceptual assessment of each subject with dysphonia was made by three voice therapists, followed by self-assessment made by the subjects themselves, and the application of the V-RQOL protocol. RESULTS: The results have shown poor level of agreement between vocal assessment made by the voice therapists and self-assessment made by the subjects. The statistical analysis indicated that the results of V-RQOL protocol showed significant correlation with the vocal assessment made by the voice therapists and the self-assessment by the subjects. CONCLUSIONS: The agreement between the assessments was low and variable; age, gender, professional voice use, and clinical laryngoscopic diagnosis did not influence the agreement level. Protocol V-RQOL is sensitive to vocal assessment made by the voice therapists and self-assessment made by the patient.

Correlation between voice and life quality and occupation.

UNLABELLED: Dysphonia may impair the quality of communication and social relations of people, thereby directly affecting quality of life. It is common knowledge amongst professionals involved with the treatment of voice disorders the need for objective protocols to evaluate voice quality and measure its impact on the individual's quality of life. AIM: To associate life quality with the degree of dysphonia and professional voice use in a group of dysphonic patients. MATERIALS AND METHODS: A prospective clinical study was undertaken with a group of dysphonic patients using an internationally validated voice-related quality-of-life protocol. A statistical analysis of the results was carried out, not distinguishing between those who use their voices professionally and those who don't. RESULTS: Dysphonia had an impact on the quality of life of all patients. There was no statistically significant difference between the groups - professional users and non-users of their voices; however, considering the groups separately, this correlation was significant only in the group of patients who do not use their voices professionally. CONCLUSION: Dysphonia affected the quality of life of all subjects regardless of their voice use.

Correlação da qualidade de vida e voz com atividade profissional / Correlation between voice and life quality and occupation

As disfonias podem comprometer a qualidade da comunicação e, por conseqüência, a relação social do indivíduo e assim afetar sua qualidade de vida. Existe hoje necessidade de protocolos objetivos para avaliação da qualidade vocal que mensurem suas implicações na qualidade de vida do paciente. OBJETIVOS: Relacionar qualidade de vida e voz com o grau de disfonia e o uso profissional da voz em um grupo de pacientes disfônicos. MATERIAL E MÉTODO: Realizou-se estudo clínico prospectivo aplicando-se protocolo internacional para avaliar a qualidade de vida e voz em um grupo de pacientes disfônicos. Realizou-se tratamento estatístico dos resultados considerando-se não-distinção entre profissionais da voz e não-profissionais da voz e, em seguida, considerando-se esta distinção profissional. RESULTADOS: A disfonia afetou a qualidade de vida em todos os indivíduos. Não houve diferença estatística entre os grupos, profissionais da voz e não-profissionais da voz, quanto ao grau de disfonia. Houve correlação entre qualidade de vida e grau de disfonia, no entanto, considerando-se os grupos separadamente, esta correlação foi significativa apenas no grupo de sujeitos não-profissionais da voz. CONCLUSÃO: A disfonia afetou a qualidade de vida em todos os sujeitos independente do uso profissional da voz.

Botulinum toxin in speech rehabilitation with voice prosthesis after total laryngectomy.

UNLABELLED: In tracheo esophageal puncture (TEP), we carry out a myotomy of the pharynx constrictor muscle; however, about 9 to 79% of patients need such procedure. The consequence of such procedure is an increase in salivary fistula rates in the postoperative. Botulin toxin is used in an outpatient basis. AIM: analyzing the efficacy of botulin toxin (BT) use in the rehabilitation of totally laryngectomized patients with tracheo-esophageal voice (TEV) with spasms (S) of the pharyngo-esophageal segment (PES) without myotomy. MATERIALS AND METHODS: We analyzed eight patients submitted to total laryngectomy (TL), rehabilitated with TEV, with speech prosthesis (SP) and struggle to utter voice because of PES spasms. They were all submitted to treatment of such motor alteration with the injection of 100 units of BT in the PES. The evaluation was based on perceptive voice analysis, video fluoroscopy (VF) of the PES, acoustic voice analysis and computerized manometry (CM) of the PES, all before and after BT injection. STUDY DESIGN: prospective. RESULTS: There was a reduction in PES CM pressure after BT injection. Acoustic analysis showed an improvement in harmonics quality after treatment. There was smoother voice utterance and spasm improvement after BT. CONCLUSION: all patients with PES spasms presented vocal improvement after BT injection in the PES.

Reabilitação fonatória do laringectomizado total: utilização de toxina botulínica na voz tráqueo-esofágica com prótese fonatória / Botulinum toxin in speech rehabilitation with voice prosthesis after total laryngectomy

Na punção tráqueo-esofágica(PTE) é realizada miotomia do músculo constritor da faringe, mas sua necessidade é entre 9 por cento a 79 por cento dos pacientes. Sua realização pode aumentar as taxas de fístula salivar no pós-operatório. A aplicação da TB é ambulatorial. OBJETIVO: Análise da eficácia da aplicação de toxina botulínica (TB), na reabilitação do laringectomizado total com voz tráqueo-esofágica(VTE) com espasmo(E) do segmento faringo-esofágico (SFE) sem miotomia. MATERIAL E MÉTODOS: Análise de oito pacientes submetidos à laringectomia total (LT), reabilitados com VTE com prótese fonatória (PF), esforço para emissão de voz devido à E do SFE. Todos submetidos a tratamento dessa alteração motora com injeção de 100 unidades de TB no SFE. A avaliação constituiu-se de análise perceptiva de voz, videofluoroscopia (VF) do SFE, análise acústica de voz e manometria computadorizada (MC) do SFE, todos antes e após aplicação de TB. DESENHO DE ESTUDO: Estudo prospectivo. RESULTADOS: Houve diminuição na pressão à MC do SFE, após a injeção de TB. Análise acústica demonstrou melhora na qualidade de harmônicos após o tratamento. Houve emissão de voz sem esforço e melhora do E após o uso da TB. CONCLUSÃO: Todos os pacientes com E do SFE apresentaram melhora vocal após aplicação da TB neste SFE.

Proposta de modelo de atendimento multidisciplinar para disfonias relacionadas ao trabalho: estudo preliminar / Multidisciplinary protocol proposal for professional dysphonia: preliminary study

A disfonia tem recebido um enfoque ocupacional crescente e torna-se necessário, ao otorrinolaringologista, atualizar a abordagem clínica dos trabalhadores que usam a voz como instrumento de trabalho, onde novas catagorias profissionais têm surgido e, com elas, as disfunções vocais conseqüentes às condições de trabalho. Hoje, há grandes preocupações com o prejuízo econômico e produtivo que o ditúrbio vocal possa gerar. Sabe-se que a disfunção vocal tem como característica a multicausalidade e, por isso, a avaliação, conclusão e emissão de relatórios médicos tornam-se incertos. OBJETIVO: Para melhor avaliar estes profissionais e garantir um atendimento com respaldo científico adequado, estabeleceu-se um protocolo multidisciplinar, que consiste em anamnese dirigida, exame físico, endoscopia laríngea, análise perceptiva da voz e aplicação do Voice Handicap Index (VHI). FORMA DE ESTUDO: Coorte histórica transversal. MATERIAL E MÉTODO: Para testar o uso do método, em caráter preliminar, o protocolo foi aplicado em 15 profissionais que usavam a voz para trabalhar. Então, realizou-se um estudo retrospectivo com estes pacientes. RESULTADO: Demonstrou-se que 13,3 por cento dos profissionais apresentaram performance vocal normal; 33,3 por cento, disfonia funcional e 46 por cento, disfonia orgânico-funcional. A disfunção vocal foi relacionada ao exercício do trabalho em 40 por cento dos pacientes e em 46,6 por cento ela foi descartada. CONCLUSÃO: Concluiu-se que o método é suficientemente abrangente e pode ser de utilidade ao otorrinolaringologista, para a avaliação clínico-ocupacional deste grupo de pacientes.
