Introduction: Nasotracheal intubation (NTI) is preferred for general anesthesia in maxillofacial surgery. However, NTI is often traumatic or even unsuccessful, particularly in patients with a narrow nasal pathway. In this case report, we describe a less traumatic NTI approach using maxillary downfracture of Le Fort I osteotomy. Case presentation: A 19-year-old woman was admitted with a skeletal Class III malocclusion and scheduled to undergo bimaxillary orthognathic surgery. A preoperative evaluation revealed no other medical history and abnormal laboratory findings. Preoperative computed tomography showed nasal septal deviation, concha bullosa. and turbinate hypertrophy. A nasal Ring-Adair-Elwyn endotracheal tube and a tube exchanger could not be inserted via NTI because of her narrow nasal cavity. An oral intubation was performed temporarily and surgery was started. After a maxillary downfracture was performed, which made the nasal cavity wider than before, NTI was successfully conducted without difficulty. The patient was ventilated without any problems, and the operation was continued. Postoperatively, the patient had no further complications and her vital parameters were all stable. Conclusions: This case report suggests that NTI after maxillary downfracture of Le Fort I osteotomy can be a good alternative that can be successfully performed with less trauma in patients undergoing orthognathic surgery who are preoperatively evaluated as having a narrow nasal cavity.
