RationaleCrouzon syndrome is an extremely rare craniofacial dysplasia, which is mainly caused by the early ossification and closure of the coronal suture of the skull. Craniofacial deformities can cause stenosis of the nasal cavity and posterior nasal meatus, resulting in sleep apnea.Patient ConcernsA 9-year-old boy with sleep snoring for 6 years, progressive aggravation in the past 1 month and accompanied by apnea during sleep.DiagnosesThis case was diagnosed with Crouzon syndrome complicated with severe obstructive sleep apnea and severe hypoxemia.InterventionsAfter adenoidectomy, he was admitted to the pediatric intensive care unit with ventilator-assisted respiration. During this period, the blood oxygen saturation fluctuated greatly. After trying to extubate, the blood oxygen was difficult to maintain and had to be intubated again. After active treatment, extubation was successful.OutcomesThe wound of nasopharynx recovered well and the sleep state was significantly improved 3 months postoperation.LessonsIt is suggested that the time of ventilator-assisted breathing should be prolonged and the perioperative airway management should be strengthened in order to reduce the risk of postoperative complications.Copyright © 2024 the Author(s).
