AbstractThe endoscopic endonasal transsphenoidal (EET) approach for skull base tumors has become increasingly popular. We know that bone defects in the skull base can cause cerebrospinal fluid rhinorrhea, but for patients who need to be intubated through the nose, the tube can enter the brain through a skull base bone defect. Nasogastric tube feeding into the brain is a rare occurrence, and this situation can occur only in the case of a skull base defect. We treated a patient with an unusual complication after the EET approach for pituitary adenoma resection. This particular case suggests that bone defects after EET surgery can not only cause cerebrospinal fluid rhinorrhea but also allow the entry of a nasogastric tube into the brain. For patients with a history of EET surgery, endoscopy-assisted gastric tube implantation can be performed if necessary.Copyright © 2019 Elsevier Inc. All rights reserved.
