ABSTRACT
OBJECTIVES:
To determine whether Sommerlad palate re-repairs and Hynes pharyngoplasties cause obstructive sleep apnea/hypopnea or increased upper airway resistance.DESIGN:
Prospective before-and-after study.SETTING:
Tertiary cleft unit. PATIENTS A total of 44 patients undergoing a Sommerlad palate re-repair or a Hynes pharyngoplasty.Interventions:
Preoperative and postoperative multichannel cardiorespiratory sleep studies. MAIN OUTCOMEMEASURES:
The main outcome measures were mean arterial oxygen saturation, desaturation index, percentage of time spent with arterial oxygen saturation <90%, mean pulse rate, number of pulse rate rises (arousals) per hour, inspiratory effort derived from pulse transit time, pulse transit time arousals, and snoring.RESULTS:
No patient in either group required intervention for airway obstruction or obstructive sleep apnea/hypopnea. Re-repairs caused no significant change in any parameter. Hynes caused an increase in inspiratory effort (P = .04) and obstructive sleep apnea/hypopnea grading (P = .002). All other parameters showed no significant deterioration. No patient developed more than mild/moderate obstructive sleep apnea/hypopnea. Snoring and arterial oxygen saturation levels were not reliable indicators of increased inspiratory effort.CONCLUSIONS:
A palate re-repair had no significant adverse effect on the airway. A Hynes, in patients with optimized velar function, caused a significant increase in inspiratory effort and obstructive sleep apnea/hypopnea grade. However, compared with studies on midline flaps and on sphincter pharyngoplasties, a Hynes appears to be less obstructive. Failure to study changes in inspiratory effort in patients undergoing velopharyngeal incompetence surgery may underestimate the obstructive effect of pharyngoplasties.
