Postoperative management following sphincter pharyngoplasty

Objective: To evaluate postoperative airway-associated outcomes following sphincter pharyngoplasty.

Study design: Case series with chart review.

Setting: Academic tertiary care medical center.

Subjects and methods: Postoperative management of sphincter pharyngoplasty (SP) conventionally includes overnight observation to monitor for upper airway obstruction. To evaluate for postoperative airway-related outcomes, 36 patients who underwent SP between April 2003 and January 2009 were evaluated retrospectively.

Results: Mean patient age was 8.1 (SD 4.3) years. Mean follow-up was 6.5 (SD 10.7) months. Cleft palate (36.1%), velo-cardio-facial syndrome (22.2%), and post-adenoidectomy (16.7%) were the most common causes of velopharyngeal insufficiency. All patients underwent overnight observation postoperatively. Mean hospital stay was 1.2 (SD 0.5) days. Five patients remained inpatient two or three days owing to fever (2 patients), bleeding ear after concurrent otoplasty (1 patient), minimal oropharyngeal bleeding with spontaneous resolution (1 patient), and medication allergy (1 patient). No patient had a documented apneic event or desaturation below 95 percent. Although no desaturations were documented, four patients received supplemental oxygen: three for less than two hours, and one for 12 hours. All patients had adequate oral intake and pain control on oral medications prior to discharge; nine patients required one to three doses of intravenous narcotic medication for pain on postoperative day zero.

Conclusion: Upper airway obstruction requiring overnight observation following SP is uncommon. In otherwise healthy patients, performing SP in an outpatient setting, given appropriate recovery room evaluation for airway concerns, oral intake, and pain control, should be considered.
