ABSTRACT

A forma respiratória da distonia laríngea é rara, de difícil diagnóstico e provoca restrição respiratória de graus variados. O objetivo deste trabalho é apresentar um caso de distonia respiratória envolvendo laringe e faringe e sua evolução em relação à intensidade dos espasmos e seu controle. ESTUDO DE CASO: Paciente de 24 anos, sexo masculino, acompanhado por 5 anos: diagnóstico por nasofibroscopia e eletromiografia e tratamento com toxina botulínica conforme necessidade de controle dos sintomas. CONCLUSÃO: O difícil manejo se deve ao fato do desconhecimento da etiologia e a pouca opção de tratamento, bem como do envolvimento da função respiratória.

The objective of the study is to report the case of a patient with respiratory dystonia involving the larynx and the pharynx and its evolution concerning spasms intensity and control. CASE REPORT: A 24 year-old-man has been followed for 5 years. The diagnosis was made by means of nasofibroscopy and electromyography. Treatment was carried out with laryngeal and pharyngeal Botulin toxin injections, as it became necessary for symptoms control.
