Study Summary

Obstructive sleep apnea occurs in 2-4% of middle age adults and results in significant morbidity and mortality. The first line therapy is provision of continuous positive airway pressure (CPAP) via a nasal mask chronically. Nasal resistance related to nasal turbinate enlargement may compromise CPAP treatment. This randomized double-blind sham-placebo-controlled trial tests the hypothesis that nasal turbinate reduction improves the nasal passage, CPAP use, and sleep apnea quality of life in newly diagnosed sleep apnea patients who are recommended CPAP therapy.

Interventions
