Anterior cervical spine fusion and sleep disordered breathing.

Abstract

The authors reviewed 12 patients who developed obstructive sleep apnea (OSA) syndrome in association with anterior cervical spine fusion. Four subsequent patients were studied prospectively before C2 to C4 anterior fusion and documented to have OSA by questionnaire, visual analogue scales, polysomnography, and multiple sleep latency tests. The authors found that placement of the anterior cervical plates reduced the size of the upper airway. Symptoms and objective findings were controlled with nasal continuous positive airway pressure.
