Summary

Introduction: The post-polio syndrome (PPS) is characterized by a new episod of atrophy or muscle weakness in individuals previously affected by poliomyelitis. The symptoms start from an extended period of clinical stability ranging from 20 to 40 years, after the initial chart of polio. Among the pathophysiological mechanisms, the most likely is that the syndrome represents a process of attrition and neuronal metabolic exhaustion due to a continuous process of denervation reinnervation which begins after the initial acute.

Objective: Review the clinical characteristics and pathophysiological of PPS,as well as present the approach in cases with pharyngolaryngeal manifestations.

Case Report: We present the clinical case of a male patient with 48 years old, with main complaints of dysphonia, dysphagia and previous history of polio. The patient underwent a diagnostic investigation, in which the voice psychoacoustic findings are described. Laringoscopic, electromyographic and the videoendoscopy of swallowing compatible with PPS. The treatment consisted in phonotherapy in a total of 11 weekly sessions and guidelines for swallowing, with satisfactory improvement of the symptoms.

Final comments: The pharyngolaryngeal manifestations of PPS are susceptible to treatment, obtaining satisfactory results, with improvement of life quality of the patients.

Resumo

Introdução: A Síndrome pós-poliomielite (SPP) caracteriza-se por um novo episódio de atrofia ou fraqueza muscular em indivíduos acometidos por poliomielite prévia. Os sintomas iniciam-se após um período prolongado de estabilidade clínica que varia de 20 a 40 anos depois do quadro inicial da poliomielite. Dentre os mecanismos fisiopatológicos, o mais provável é que a síndrome represente um processo de desgaste e exaustão metabólica neuronal devido a um processo contínuo de desnervação-reinervação que se inicia após o quadro agudo inicial.

Objetivo: Revisar as características clínicas e fisiopatológicas da SPP, assim como apresentar a abordagem em casos com manifestações faringo-laríngeas.

Relato do Caso: Apresentamos o caso clínico de um paciente masculino com 48 anos de idade, com queixas principais disfonia e disfagia e história prévia de poliomielite. O paciente foi submetido à investigação diagnóstica, na qual encontram-se descritos os achados psicoacústicos da voz, laringoscópicos, eletromiográficos e da videoendoscopia da deglutição compatíveis com SPP. O tratamento consistiu em fonoterapia num total de 11 sessões semanais e orientações gerais para deglutição com melhora satisfatória dos sintomas.

Comentários Finais: As manifestações faringo-laríngeas da SPP são passíveis de tratamento, obtendo-se resultados satisfatórios com melhora na qualidade de vida dos pacientes.
