In multivariate regression controlling for age, sex, syndrome status, and orofacial cleft history, use of patient-specific mandibular plates was associated with infection (p = 0.017; adjusted OR, 12.5), any complication (p = 0.007; adjusted OR, 11.8), readmission (p = 0.001; adjusted OR, 17.9), and reoperation (p = 0.001; adjusted OR, 18.9). In the era of patient-specific orthognathic surgery, syndromic status and use of patient-specific mandibular plates are associated with increased infection, readmission, and reoperation because of hardware-related complications. The authors' data support increased caution and counseling with use of patient-specific mandibular implants in patients with syndromic status, history of orofacial cleft, and history of previous maxillomandibular surgery given increased risk of hardware-related complications. Therapeutic, III. Therapeutic, III. Robin sequence is a common cause of upper airway obstruction in newborns. Herein, we report sleep outcomes in neonates undergoing external mandibular distraction osteogenesis. In this retrospective, 14-year, single-institution study of neonates with Robin sequence undergoing mandibular distraction osteogenesis, we compare respiratory parameters and sleep architecture before versus after surgery. Thirty-one neonates were included; age was 13 days (interquartile range, 5 to 34 days) at preoperative polysomnography and 80 days (interquartile range, 50 to 98 days) at postoperative polysomnography. All neonates had severe obstructive sleep apnea at baseline (defined as pre-operative obstructive apnea hypopnea index ≥ 10). Postoperatively, there was a significant reduction in obstructive apnea hypopnea index [38.3 (interquartile range, 23.4 to 61.8) preoperatively versus 9.4 (interquartile range, 5.3 to 17.1) postoperatively; p < 0.0001], and a significan
