Introduction Dysphagia is a common symptom in children with cerebral palsy, either in oral or pharyngeal phases. Children who face such difficulties tend to show health problems such as food aspiration, malnutrition and respiratory infections. Videofluoroscopic swallowing study is the most recommended for these cases, as it reveals the real situation during swallowing. Objective The study aimed to verify the occurrence of aspiration pneumonia in children with cerebral palsy after videofluoroscopy. Methods The population for this prospective cross-sectional study involved 103 children with cerebral palsy, referred for videofluoroscopic who had returned for medical examination after a week to search for signs and symptoms of pneumonia. Results The study involved 46 girls (44.66%) and 57 boys (55.34%), aged between 0 and 14 years of age. Of the total, 84 (81.5%) had dysphagia, of which 24 (23.3%) were severe, 8 (7.7%) were moderate and 52 (50.4%) were mild dysphagia. None of the children presented aspiration pneumonia or infectious complications during the course of videofluoroscopy or after the procedure. Conclusion In the population studied, the authors found no cases of aspiration pneumonia, even with tracheal aspiration present in 32 (31.07%) cases.

The most evident neurotological symptoms were dizziness, lack of coordination of movement, and imbalance when walking. Alterations in vestibular examinations occurred in 89.5% of patients, mostly in the caloric test, with a predominance of deficient central vestibular system dysfunction. This underscores the importance of the contribution of topodiagnostic labyrinthine evaluations for neurodegenerative diseases.

original RESUMONos paciente acometidos de acidente vascular cerebral (AVC), a disfagia é uma das complicações de maior incidência e pode resultar em pneumonia aspirativa. Objetivo. Relacionar o valor do tempo máxi-mo de fonação (TMF) na emissão da vogal /e/ sustentada em pacientes com disfagia neurogênica e a presença de aspiração laringotraqueal. Método. Estudados 38 pacientes adultos, 22 (57,9%) do sexo masculino e 16 (48,1%) do sexo feminino, na faixa etária mínima de 40 anos e a máxima de 85 anos. Divididos em grupo menor que 10s e acima ou igual a 10s. Utilizou-se valores do TMF na emissão da vogal /e/ aberta sustentada comparados com achados do exame endoscópico da deglutição. Resultados. A relação do TMF na emissão da vogal /e/ sustentada, nos pacientes com disfagia neurogênica secundária a AVC, não apresentou significância estatística para presença de aspiração laringotraqueal. Conclusão. O TMF reduzido não significa presença de aspiração laringotraqueal, tornando ineficaz a sua utilização na prática clínica. Novos estudos são necessários para definir parâmetros de segurança na avaliação do paciente com AVC e disfagia neurogênica. ABSTRACTIn stroke patients dysphagia is a higher incidence of complications and may result in aspiration pneumonia. Objective. To relate the value of the maximum phonation time (MPT) in the vowel / e / sustained in patients with neurogenic dysphagia and the presence of tracheal aspiration. Method. We studied 38 adult patients, 22 (57.9%) males and 16 (48.1%) females, from 40 to 85 years. They were divided into groups smaller than 10s and above or equal to 10s. We used values of TMF in vowel / e / open sustained compared with endoscopic examination findings swallowing. Results. The ratio of the MPT vowel / e / sustained in patients with neurogenic dysphagia secondary to stroke, showed no statistical significance for the presence of tracheal aspiration. Conclusion. The reduced TMF does not mean the presence of tracheal aspiration, rendering ineffective its use in clinical practice. Further studies are needed to define security parameters in the evaluation of patients with stroke and neurogenic dysphagia.

Sumarry Introduction: Spinocerebellar ataxia (SCA) is a degenerative disease that can cause loss of coordination of voluntary muscle movement such as that required for swallowing. Aims: The purposes of this cross-sectional and comparative case study were: (1) to assess the severity of dysphagia through a videofluoroscopic swallow study, and (2) to compare differences in frequency, intensity, and duration of sound waves produced during swallowing in normal and SCA patients by using sonar Doppler. Method: During swallow evaluation using videofluoroscopy, a sonar Doppler transducer was placed on the right side of the neck, at the lateral edge of the trachea, just below the cricoid cartilage to capture the sounds of swallowing in 30 SCA patients and 30 controls. Result: The prevalence in the dynamic evaluation of swallowing videofluoroscopy was by changes in the oral phase of swallowing. The analysis of variance of the averages found in each variable - frequency, intensity and duration of swallowing - shows there was a significant correlation when compared to the healthy individual curve. Conclusion: The study demonstrates the prevalence of oral dysphagia observed in dynamic videofluoroscopic swallow evaluation. In patients with SCA, the mean initial frequency (IF), initial intensity (II), and final intensity (FI) were higher and the time (T) and peak frequency (PF) were lower, demonstrating a pattern of cricopharyngeal opening very close to that found in normal populations.
