Laryngopharyngeal sensory testing can predict aspiration risk in adult patients. Its feasibility and potential role in the evaluation of pediatric swallowing is undetermined. The goals of this study were to determine the feasibility of performing laryngopharyngeal sensory testing in awake pediatric patients and to assess whether the sensory testing results correlated with aspiration during a feeding assessment or correlated with a history of pneumonia. Fiberoptic endoscopic evaluation of swallowing with sensory testing was performed in 100 pediatric patients who were evaluated for feeding and swallowing disorders. The swallowing function parameters evaluated were pooled secretions, laryngeal penetration, and aspiration. The laryngopharyngeal sensory tests were performed by delivering a pressure-controlled and duration-controlled air pulse to the aryepiglottic fold through a flexible laryngoscope to induce the laryngeal adductor response (LAR). The air pulse stimulus ranged in intensity from 3 to 10 mm Hg. The patients tested ranged from 1 month to 24 years of age, with a median age of 2.7 years. Sensory testing was completed in 92% of patients. Patients who had an LAR at less than 4 mm Hg rarely if ever had episodes of laryngeal penetration or aspiration. Those with an LAR at 4 to 10 mm Hg had variable amounts of aspiration and laryngeal penetration. The LAR could not be elicited at the maximum level of intensity (10 mm Hg) in 22 patients, who demonstrated severe laryngeal penetration and/or aspiration. Elevated laryngopharyngeal sensory thresholds correlated positively with previous clinical diagnoses of recurrent pneumonia, neurologic disorders, and gastroesophageal reflux, and correlated positively with findings of pooled secretions, laryngeal penetration, and aspiration. Laryngopharyngeal sensory testing in children is feasible and correlative.
