RESUMO
OBJECTIVE: To describe the findings of videofluoroscopic study (VFSS) and investigate the usefulness of VFSS as a predictor of aspiration pneumonia in infants with aspiration symptoms. METHOD: Thirty-eight infants with aspiration symptoms were divided into two groups: those who showed aspiration symptom but had no pneumonia (Aspiration group); those with episode of aspiration pneumonia (Pneumonia group). The subjects' medical records and the results of VFSS were reviewed. RESULTS: In aspiration group, oral phase was normal and the abnormalities were found only in pharygeal phase in a small number of subjects. On the other hand, pneumonia groups showed poor lip closure and bolus formation in oral phase. Abnormalities of pharyngeal phase were reduced laryngeal elevation, coating of pharyngeal wall, increased residue of valleculae, and delay of pharyngeal transit time. Penetration and aspiration were more frequently observed (p <0.05). Aspiration pneumonia occurred more frequently among infants who had supraglottic penetration (p <0.05). CONCLUSION: Mild abnormalities were found only in pharyngeal phase in aspiration group, whereas VFSS abnormalities were observed in both oral and pharyngeal phase in infants with pneumonia. Our results suggest that VFSS would be useful in predicting the development of pneumonia in infants with aspiration symptoms.
