Analysis of oropharyngeal dysphagia through fibroendoscopy evaluation of swallowing in patients with Parkinson's disease.

BACKGROUND: Parkinson's disease (PD) has a high incidence in Mexico and is estimated at approximately 500,000 patients. One of the main clinical manifestations of PD is dysphagia, which is the difficult passage of food from the mouth to the stomach. The aim of this study was to assess oropharyngeal dysphagia through fibroendoscopy evaluation of swallowing in patients with PD. METHODS: We conducted a census sample of patients with PD: 17 males and 10 females, aged >49 years. Clinical history, physical examination and neurological evaluation of swallowing fibroendoscopy were carried out. RESULTS: Of the symptomatic patients, 16 patients (59.25%) reported dysphagia. Fibroendoscopic evaluation demonstrated swallowing disorders in 25 patients (92.59%). The main findings were poor bolus control in 19 patients (70.37%), deficits in bolus propulsion in 25 patients (92.59%), impaired swallowing in 14 patients (51.85%), fractional swallowing in 11 patients (40.74%), reduced epiglottic tilting in 11 patients (48.14%), food residue in vallecula in 24 patients (88.88%) and piriform sinus in 19 patients (70.37%). There was no correlation between duration of PD and degree of involvement of oropharyngeal dysphagia. CONCLUSIONS: Oropharyngeal dysphagia in patients with PD is a common symptom and can range from the oral cavity to the upper esophageal sphincter. Early onset of severe dysphagia is exceptional in this disease and should alert the clinician to the diagnostic possibility of parkinsonism.

Nódulos vocais: análise anátomo-funcional / Vocal nodules: functional and anatomical analysis

Objetivo: traçar o perfil epidemiológico/clínico de uma população portadora de nódulos vocais diagnosticados e comparar os tipos de fendas glóticas à fonação. Métodos: foram avaliados os registros de 70 pacientes portadores de nódulos vocais diagnosticados através de exame videolaringoestroboscópico no período de junho de 2003 a maio de 2004. As imagens arquivadas foram analisadas por quatro fonoaudiólogos e dois otorrinolaringologistas, conforme os seguintes parâmetros: simetria laríngea, aspecto da lesão, tipo de fenda, onda mucosa, movimento muco-ondulatório, amplitude de vibração, presença de sinais de refluxo e constrição supraglótica. Resultados: os dadosencontrados apontam maior incidência de nódulos vocais em mulheres adultas que utilizavam a voz profissionalmente. Clinicamente, não houve associação significativa entre pacientes fumantes com queixa de refluxo e pacientes portadores de nódulos. Ao exame videolaringoestroboscópico observamos:87,4% de lesões bilaterais e 12,6% unilaterais. O fechamento supraglótico medial ocorreu em apenas 01 caso, sendo caracterizado como unilateral e não participando da fonação. Em 3 pacientes identificou-se a presença de microweb. Todos os pacientes apresentaram fenda glótica, sendo 90,9% delas classificadas como dupla. Conclusão: a amostra foi composta predominantemente por mulheres,com idade média de 34,64 anos, não fumantes, professoras, trabalhando em três turnos, cuja queixa de rouquidão teve duração média de 5,68 meses, apresentando ao exame laringe simétricacom nódulos bilaterais, de igual tamanho. Houve significância estatística apontando proporção maior de fendas duplas.

Purpose: to determine the epidemiological/clinical profile of patients with vocal nodules, and comparetheir glottic closure during phonation. Methods: seventy vocal nodules patients were evaluated by videolaryngostroboscopy at Instituto de Otorrinolaringologia de Minas Gerais, from June 2003 to May 2004. The video images were analyzed by 4 speech therapists and 2 otorhinolaryngologists, according to the following criteria: laryngeal symmetry, lesion aspect, kind of glottic closure, mucous wave, vocalfold vibration ,vibratory amplitude, gastroesophageal reflux signals and supraglottalconstriction. Results: Data showed that the highest incidence was found with adult professional voice user females. Clinically, it was observed that there was no meaningful relationship among smoking patients or the ones withgastroesophageal reflux and those with vocal nodules. The videolaryngostroboscopy showed: 87.4% bilateral lesions and 12.6% unilateral lesions. We noted that medial supraglottal closure was found injust one case, characterized as an unilateral lesion and with no participation during phonation. Threesubjects presented a Microweb. All patients had incomplete glottal closure and 90.9% of them were classified as double. Conclusion: the sample was composed mainly by non- smoking female teachers, about 34 years old, involved in a three journey workday with a 5.68 moths hoarseness complaintpresenting laryngeal symmetry, and bilateral nodules same size. There was a statistically significant proportion of incomplete glottal closure.
