Abstract Introduction Sensory deficits of the upper airways are common in people with Parkinson disease. Compounded by considerable deterioration of the swallowing function, these deficits may contribute to the elevated rates of morbidity and mortality among this population. Objective To examine the sensitivity of the vocal tracts of people with Parkinson disease using nasal videoendoscopy and to compare the results with paired controls. Methods The present was a prospective, observational, case-control study. Sensitivity assessments were conducted in a sample of 24 people divided into 2 groups: one group of 12 patients with Parkinson’s disease, and a control group with 12 healthy subjects. The study group also underwent a fiberoptic endoscopic evaluation of swallowing and answered the Swallowing Disturbance Questionnaire (SQD) to detect dysphagia. Results There was a significant difference (p < 0.05) in the region of the arytenoid cartilages, showing that sensitivity was better preserved among the control group, and that sensitivity deficits were present in the study group. The qualitative results showed sensorial impairment in the study group than in the control group regarding the base of the tongue, the vestibular folds, and the vocal folds. The study group showed self-awareness regarding the deficits in the swallowing function, but there was no statistically significant association between swallowing function deficits and deterioration of sensorial function among them. Conclusions Sensorial deficits were present in the study group when compared to the healthy subjects, mainly in the qualitative evaluation.

RESUMO Objetivo Descrever e caracterizar um achado, o escape posterior tardio de resíduo alimentar na deglutição, segundo idade, gênero e consistência do alimento, que ocorreu no evento. Método A coleta de dados ocorreu por meio da análise de cada exame de videonasoendoscopia funcional da deglutição anteriormente gravado em um ambulatório especializado. A população do estudo contemplou 200 pacientes de ambos os gêneros, na faixa etária entre 46 e 87 anos, com e sem patologia de base para disfagia. As imagens foram estudadas individualmente pelo pesquisador e analisadas por juízes, com o objetivo de identificar e selecionar imagens que constatassem a presença ou ausência do evento em estudo. Resultados Verificou-se o escape tardio em 45 exames do total de 200 analisados. Os exames selecionados para o estudo apresentaram o escape residual posterior tardio em pelo menos uma consistência. A maior frequência do escape posterior tardio ocorreu com o líquido. A análise mostrou significância do evento em estudo com a população que apresentava idades mais avançadas da nossa amostra. Conclusão O escape posterior tardio ocorre predominantemente na consistência líquida, em população mais idosa e sem predomínio de gênero.

ABSTRACT Purpose To describe and characterize a finding, i.e., delayed posterior leakage of food residue during swallowing, according to age, gender and food consistency, which occurred in the event. Methods Data were collected through the analysis of each functional videonasoendoscopy test of swallowing previously recorded in a specialist outpatient clinic. The study population included 200 patients, both males and females, aged between 46 and 87 years, with and without an underlying pathology for dysphagia. The images were studied individually by the researcher and analyzed by judges in order to identify and select images that would confirm the presence or absence of the study event. Results Delayed escape was found in 45 out of the 200 analyzed tests. The tests selected for the study showed delayed posterior bolus leakage in at least one consistency. The highest frequency of delayed posterior leakage occurred with fluids. The analysis showed the significance of the study event with the population related to older ages in the sample analyzed. Conclusion Delayed posterior leakage occurs predominantly in the liquid consistency in older populations with no gender predominance.
