Airway Obstruction following Palatoplasty: Analysis of 247 Consecutive Operations

Abstract

Objective and Methods Between February 1987 and September 1997, 247 patients underwent primary repair of a cleft of the secondary palate by one surgeon, using the double-opposing Z-plasty (Furlow) technique. This retrospective study reviews perioperative and postoperative airway compromise among these patients. The purposes of this study were to identify factors associated with airway obstruction following palatoplasty and to analyze the management of those patients. Although infants experiencing airway problems following Wardill-Kilner and Von Langenbeck palatoplasty have been described, airway complications in a group of Furlow repair patients has not been previously reported. Results Fourteen patients (5.7%) had airway problems. The average age of these patients was 18 months, which was not significantly different from those without airway problems. Airway obstruction occurred as late as 48 hours after the completion of surgery. Twelve of the 14 patients had severe airway compromise requiring continued postoperative intubation, reintubation, or tracheostomy (one). There were no deaths. Thirteen of the 14 patients with postoperative airway problems (93%) had other congenital anomalies in addition to clefting, a named congenital disorder, or both. Seven of those 13 had Pierre Robin sequence. In contrast, only 40 of the 233 patients without airway problems (17%) had additional congenital anomalies or named disorders. Presence of other congenital anomalies was associated with a significantly increased risk of airway obstruction (p = .005). Conclusion Patients with cleft palate with the Pierre Robin sequence or other additional congenital anomalies had an increased risk of airway problems following palatoplasty. Awareness of this risk permits identifying those patients prior to surgery so that they can be monitored and managed appropriately, minimizing the likelihood of major complications or death.
