Perioperative Airway Complications following Pharyngeal Flap Palatoplasty

This study was performed to determine the incidence and types of perioperative airway complications after pharyngeal flap palatoplasty. We conducted a retrospective chart review of 88 patients who underwent correction of velopharyngeal insufficiency between April 30, 1983, and April 30, 1997, in a tertiary care hospital. Some degree of airway obstruction developed in 7 patients. One child developed laryngobronchospasm and required immediate endotracheal intubation. He was successfully extubated without sequelae. Another patient developed severe obstructive sleep apnea and required flap revision. A third patient was found asystolic and apneic. She was immediately intubated; however, she subsequently died. Two patients aspirated blood, presumably resulting in pneumonia. They were managed with parenteral antibiotics. Another child developed worsening sleep apnea and required flap revision. One patient developed nasal obstruction that resolved with time. Airway compromise in patients who undergo pharyngeal flap palatoplasty can be a potentially fatal complication. Careful surveillance should be maintained over patients with underlying neurologic, craniofacial, or cardiopulmonary disorders.
