Unplanned Intensive Care Unit Admission Following Cleft Palate Repair by Head and Neck Surgeons.

OBJECTIVE: To examine the incidence of pediatric intensive care unit (PICU) admission following primary repair of cleft palate by otolaryngologist-head and neck surgeons at 2 tertiary centers. To identify potential diagnoses associated with admission or unanticipated PICU transfer. STUDY DESIGN: Multi-institutional case series with chart review. SETTING: Two tertiary pediatric medical centers. METHODS: Children who underwent primary repair of cleft palate at 2 cleft centers over a 10-year period were identified. Charts were reviewed for demographics, comorbidities, and whether PICU admission was required. RESULTS: From 2009 to 2019, 464 patients underwent primary repair of a cleft palate by 1 of 6 otolaryngologist-head and neck surgeons with subspecialty training in cleft surgery; 459 patients had sufficient postoperative documentation and 443 children met inclusion criteria. The incidence of PICU admission was 9.3% (41/443), with 33 (7.4%) planned admissions and 8 (1.8%) unexpected PICU transfers. Syndromic conditions were associated with both planned and unanticipated PICU admissions. CONCLUSION: The incidence of unanticipated postoperative PICU admission following cleft palate repair by otolaryngologist-head and neck surgeons was low. Risk stratification by surgeons with expertise in airway management may inform decisions regarding postoperative disposition of patients with medical or airway complexity who are undergoing cleft palate repair.

Detection of Chronic Hypoventilation Among Infants With Robin Sequence Using Capillary Blood Gas Sampling.

OBJECTIVES/HYPOTHESIS: To describe the use of capillary blood gas (CBG) sampling to detect and quantify hypoventilation in infants with Robin sequence (RS). METHODS: Case series with chart review at two institutions. Infants with RS presenting over a 10-year period were identified using departmental databases. CBG values obtained during infancy or until airway intervention (AI) were reviewed. RESULTS: From 2008 to 2018, 111 infants with RS were identified as having had been assessed and managed from birth or transfer until discharge home and having CBG data available. In most cases, CBG sampling was obtained every other day until intervention or discharge. A total of 81 (73%) infants required AI: 72 (89%) underwent mandibular distraction osteogenesis, five (6%) underwent tracheotomy, and four (5%) were discharged home with a nasopharyngeal airway. The mean PCO2 at day of life (DOL) 7-30 for the AI group was 52.7 mmHg (95% confidence interval: 51.7-53.7) and for the no AI group was 45.9 mmHg (44.8-47.0; P < .0001). The mean HCO3 at DOL 7-30 for the AI group was 29.8 mEq/L (29.4-30.1) and for the no AI group was 27.0 mEq/L (26.5-27.4; P < .0001). Receiver operating characteristic curves were created for maximum PCO2 and HCO3 values and cutoffs were established by optimizing a balance of sensitivity and specificity. Infants requiring AI surpassed the PCO2 and HCO3 cutoff at a median of DOL 9. CONCLUSIONS: Among infants with RS and hypoventilation, objective measures of respiratory acidosis may be apparent by DOL 9. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:2789-2794, 2021.

Cleft Palate Repair by Otolaryngologist-Head and Neck Surgeons: Risk Factors for Postoperative Fistula.

OBJECTIVES/HYPOTHESIS: To assess the incidence of palatal fistula after primary repair of the cleft palate among two cohorts of Otolaryngologist-Head and Neck Surgeons and to identify patient and surgeon characteristics that may predict fistula development. STUDY DESIGN: Retrospective case series with chart review. METHODS: Children who underwent primary repair of cleft palate at one of two multidisciplinary cleft centers over a 10 year period were identified. Charts were reviewed for the presence of palatal fistula; chi square test and multivariate logistic regression analysis were performed to determine variables associated with fistula formation. RESULTS: From 2007 to 2017, 477 patients underwent primary repair of cleft palate by one of 6 Otolaryngologist-Head and Neck Surgeons. Twenty-four children had incomplete charts, allowing 453 patients to be included in the final analysis. The pooled mean incidence of palatal fistula was 6.6% (P = .525) and varied significantly by cleft type. Logistic regression analysis controlling for multiple variables, showed that Veau IV classification had the highest risk of fistula (OR = 10.582; P = .004). Repair by a specific surgeon was not a significant risk factor for fistula development (P > .07 for each surgeon). CONCLUSIONS: Among six Otolaryngologist-Head and Neck Surgeons with fellowship training in cleft palate repair postoperative fistula rates were consistent and compared favorably to standards in the Cleft and Craniofacial surgery literature established by other surgical specialties. Consistent with larger database studies involving multiple surgical specialties, Veau IV classification was the strongest predictor of palatal fistula development, even after adjusting for multiple variables, including differing levels of experience.

Multimodal Imaging Characteristics and Diagnostic Approach to Ancient Schwannoma in a Pediatric Patient.

Ancient schwannoma is an extremely rare benign, peripheral nerve sheath tumor. Despite its benign nature, its characteristic heterogeneous appearance and degenerative changes commonly lead to misdiagnosis of malignancy. Although schwannomas are extremely uncommon in the pediatric population, these neoplasms have been associated with underlying conditions such as neurofibromatosis type two, and appropriate recognition is important to ensure close monitoring of potential future symptoms secondary to other tumors. We report the imaging and laboratory findings of an ancient schwannoma of the vagus nerve in a 10-year-old female, the first documented case of such a tumor in a pediatric patient, and discuss its characteristic findings and diagnostic considerations. Awareness of this rare tumor can help promote correct diagnosis and avoidance of costly, high-risk diagnostic methods.
