Efficacy of the Addition of a Cervical Collar in the Treatment of Persistent Obstructive Apneas Despite Continuous Positive Airway Pressure.

ABSTRACT: Continuous positive airway pressure (CPAP) is currently the reference treatment for obstructive sleep apnea (OSA). The use of a face mask, although sometimes necessary, is often associated with increased airway obstruction due to mandibular retrusion. We report a small group of patients in whom addition of a cervical collar to a face mask allowed correction of obstructive events.
