Laryngeal sensory testing in the assessment of patients with laryngopharyngeal reflux.
Laryngopharyngeal reflux is commonly encountered in the ENT out-patient setting. It leads to impaired sensory capacity of the laryngeal mucosa. The sensory integrity of the laryngopharynx can be evaluated through endoscopic administration of pulsed air, which stimulates the laryngeal adductor reflex. The pressure of air needed to elicit this reflex indicates the degree of sensory impairment. Such laryngeal sensory testing gives a quantifiable means of assessment in patients with laryngopharyngeal reflux, and can be used to measure the response to treatment. Laryngeal sensory testing is safe and well tolerated by patients.
