Laryngeal diversion in the treatment of intractable aspiration in motor neuron disease.

Abstract

Motor neuron disease/amyotrophic lateral sclerosis (MND/ALS) often causes bulbar palsy with subsequent aspiration. Laryngeal diversion procedures are not commonly mentioned in the literature. However, they are viable but infrequently used surgical treatment options that have several advantages over a routine tracheostomy. We report a case of a 67-year-old man with MND/ALS and severe aspiration. He underwent a laryngeal diversion procedure with complete relief of signs and symptoms of aspiration. Laryngeal diversion, unlike tracheostomy, completely eliminates the possibility of aspiration as well as the need for suctioning. The primary disadvantage is complete loss of phonation. These procedures appear worthy of trial in patients with MND/ALS, and may ultimately be the preferred treatment in this setting.
