ABSTRACT
BACKGROUND:
To investigate a novel velopharyngeal squeeze maneuver (VPSM) and novel endoscopic pharyngeal contraction grade (EPCG) scale for the evaluation of pharyngeal motor function.METHODS:
During endoscopic examination of 77 post-irradiated nasopharyngeal carcinoma patients and control subjects, VPSM was rated and lateral pharyngeal wall movement graded with EPCG scale during swallowing. Pharyngeal constriction ratio (PCR) measured by videofluoroscopy was used for correlation.RESULTS:
VPSM and EPCG scale showed almost perfect intra-rater and inter-rater reliability (Kappa >0.90). VPSM was present in 61% of patients suggesting good pharyngeal motor function. VPSM was predictive of EPCG scale (Wald statistic = 29.99, p < 0.001). EPCG scale also correlated strongly with PCR (r 0.812) and was predictive for aspiration (odds ratio 22.14 [95% CI 5.01-97.89, p < 0.001]).CONCLUSIONS:
VPSM and EPCG scale are two novel tools to assess pharyngeal motor function, and both correlate well with pharyngeal contractility and aspiration.Palavras-chave
