Nasal continuous positive airway pressure and weight loss improve swallowing reflex in patients with obstructive sleep apnea syndrome.

We have recently reported that swallowing reflex is impaired in patients with obstructive sleep apnea syndrome (OSAS). However, the effects of OSAS treatment on swallowing function in these patients have not been reported. Here we report 2 cases of OSAS in whom swallowing reflex was impaired before the start of nasal continuous positive airway pressure (NCPAP) and improved 1 year after NCPAP. These cases suggest that impaired swallowing reflex may be reversible by OSAS treatment. Copyright 2000 S. Karger AG, Basel
