Absence of the LAR and impaired pharyngeal squeeze puts patients with dysphagia at high risk for laryngeal penetration and aspiration compared with patients with an intact LAR and intact pharyngeal squeeze. There is a strong association between motor and sensory deficits in the laryngopharynx.

TNE is well tolerated and can be safely performed in patients with dysphagia in an office setting. TNE may have a role in the comprehensive evaluation of the dysphagic patient in the office.
