Abstract

Central sleep apnea (CSA) is defined as an absence of breathing without respiratory drive during sleep. It can occur after treatment of obstructive sleep apnea (OSA), a phenomenon known as treatment-emergent central sleep apnea (TECSA). We present a case of a 23-year-old male who developed CSA after pharyngeal and nasal surgery for severe OSA. High loop gain and increased ventilations from frequent arousal are likely explanations for our patient’s central apnea, which resolved with positive airway pressure therapy that possibly alleviated residual airway obstruction and ventilatory instability. This case suggests that effectiveness of treatment for OSA should be based on careful long-term observation with multiple follow-up polysomnography tests, especially in patients at high risk of TECSA.
