The effects of upper airway surgery for obstructive sleep apnea on nasal continuous positive airway pressure settings



The effects of upper airway surgery for obstructive sleep apnea on nasal continuous positive airway pressure settings



Laryngoscope 114(2): 205-207



The objectives were to determine whether upper airway surgery lowers nasal continuous positive airway pressure (CPAP) settings for patients who require CPAP postoperatively for unresolved obstructive sleep apnea and to assess CPAP tolerability after upper airway surgery. Retrospective chart review. Patients who underwent upper airway surgery with preoperative and postoperative polysomnography at the University of Alabama at Birmingham (Birmingham, AL) between 1995 and 2000 were the focus of the study. Upper airway surgery was defined as uvulopalatopharyngoplasty alone or in addition to septoplasty and turbinoplasty. Recommended CPAP settings were recorded from preoperative and postoperative polysomnography studies to determine whether CPAP settings were decreased following surgery. A response to surgery was defined as a decrease of the recommended CPAP setting by at least 1 cm of water. A telephone interview was conducted to determine whether upper airway surgery improved CPAP comfort. In 51.4% of the patients, CPAP settings were decreased following surgery. Continuous positive airway pressure settings were increased in 28.6% of patients and unchanged in 20%. Of the six patients who consistently used CPAP before and after surgery, four reported increased comfort postoperatively. Upper airway surgery does not predictably reduce CPAP settings in the patient who requires postoperative CPAP for unresolved obstructive sleep apnea. Upper airway surgery may improve CPAP tolerability.
