Defining Risk of Postoperative Obstructive Sleep Apnea in Patients With 22q11.2DS Undergoing Pharyngeal Flap Surgery for Velopharyngeal Dysfunction Using Polysomnographic Evaluation.

OBJECTIVE: To determine pre- and postoperative prevalence of obstructive sleep apnea (OSA) in patients with 22q11.2 deletion syndrome (DS) undergoing wide posterior pharyngeal flap (PPF) surgery for velopharyngeal dysfunction (VPD). DESIGN: Retrospective study using pre- and postoperative polysomnography (PSG) to determine prevalence of OSA. Medical records were reviewed for patients' medical comorbidities. Parents were surveyed about snoring. SETTING: Academic tertiary care pediatric hospital. PATIENTS: Forty patients with laboratory confirmed 22q11.2DS followed over a 6-year period. INTERVENTIONS: Pre- and postoperative PSG, speech evaluation, and parent surveys. MAIN OUTCOME MEASURE: Severity and prevalence of OSA, defined by obstructive apnea hypopnea index (OAHI), before and after PPF surgery to determine whether PPF is associated with increased risk of OSA. RESULTS: Mean OAHI did not change significantly after PPF surgery (1.1/h vs 2.1/h, P = .330). Prevalence of clinically significant OSA (OAHI ≥ 5) was identical pre- and postoperatively (2 of 40), with both cases having severe-range OSA requiring positive airway pressure therapy. All other patients had mild-range OSA. Nasal resonance was graded as severe preoperatively in 85% of patients. None were graded as severe postoperatively. No single patient factor or parent-reported concern predicted risk of OSA (OAHI ≥ 1.5). CONCLUSIONS: Patients with 22q11.2DS are medically complex and are at increased risk of OSA at baseline. Wide PPF surgery for severe VPD does not significantly increase risk of OSA. Careful perioperative planning is essential to optimize both speech and sleep outcomes.

The Reducing Opioid Use in Children with Clefts Protocol: A Multidisciplinary Quality Improvement Effort to Reduce Perioperative Opioid Use in Patients Undergoing Cleft Surgery.

BACKGROUND: Cleft repair requires multiple operations from infancy through adolescence, with repeated exposure to opioids and their associated risks. The authors implemented a quality improvement project to reduce perioperative opioid exposure in their cleft lip/palate population. METHODS: After identifying key drivers of perioperative opioid administration, quality improvement interventions were developed to address these key drivers and reduce postoperative opioid administration from 0.30 mg/kg of morphine equivalents to 0.20 mg/kg of morphine equivalents. Data were retrospectively collected from January 1, 2015, until initiation of the quality improvement project (May 1, 2017), tracked over the 6-month quality improvement study period, and the subsequent 14 months. Metrics included morphine equivalents of opioids received during admission, administration of intraoperative nerve blocks, adherence to revised electronic medical record order sets, length of stay, and pain scores. RESULTS: The final sample included 624 patients. Before implementation (n =354), children received an average of 0.30 mg/kg of morphine equivalents postoperatively. After implementation (n = 270), children received an average of 0.14 mg/kg of morphine equivalents postoperatively (p < 0.001) without increased length of stay (28.3 versus 28.7 hours; p = 0.719) or pain at less than 6 hours (1.78 versus 1.74; p = 0.626) or more than 6 hours postoperatively (1.50 versus 1.49; p = 0.924). CONCLUSIONS: Perioperative opioid administration after cleft repair can be reduced in a relatively short period by identifying key drivers and addressing perioperative education, standardization of intraoperative pain control, and postoperative prioritization of nonopioid medications and nonpharmacologic pain control. The authors' quality improvement framework has promise for adaptation in future efforts to reduce opioid use in other surgical patient populations. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Management of velopharyngeal dysfunction in patients with 22q11.2 deletion syndrome: A survey of practice patterns.

OBJECTIVE: To determine demographics and practice patterns of surgeons treating velopharyngeal dysfunction (VPD) in patients with 22q11.2 deletion syndrome (22q11.2DS). METHODS: An anonymous electronic survey study was administered to the surgical membership of the American Cleft Palate-Craniofacial Association and the Society for Ear Nose and Throat Advances in Children. The survey queried surgeon demographics and differences in management practices for submucous cleft palate (SMCP), pharyngoplasty algorithms, and self-reported complications for nonsyndromic versus 22q11.2DS patients. RESULTS: 126 surveys were returned from 9 international regions with the majority from the United States (73%), followed by Western Europe (9.5%) and Canada (7.9%). Plastic surgery was the most common specialty (61.9%), followed by otolaryngology (27.8%). 88.1% reported fellowship training, and 33% completed multiple fellowships. Prior to proceeding with pharyngoplasty in 22q11.2DS patients, surgeons required the following assessments: speech evaluation (79.4%), velopharyngeal imaging (51.6%), cardiac evaluation (50.0%), carotid artery MRI (29.4%), and cervical spine x-rays (11.1%). Nasoendoscopy was the most common modality used for imaging the velopharynx. Overall, providers managed patients with 22q11.2DS similarly to nonsyndromic patients, with several significant exceptions including that they were more likely to perform SMCP repair alone as a first approach in nonsyndromic patients (p = 0.031) and posterior pharyngeal flap without SMCP repair in those with 22q11.2DS (p = 0.017). CONCLUSIONS: Practice patterns for the management of VPD in patients with 22q11.2DS vary across providers. Further collaborative studies are needed to develop optimal treatment paradigms for VPD in patients with 22q11.2 DS.
