[Perioperative Management of Endoscopic Endonasal Surgery].

The application of endoscopic endonasal surgery is gradually expanding to include lesions located in the midline of the skull base in addition to those in the sella turcica. Meticulous preoperative preparation and prevention and early detection of postoperative complications are important to optimize perioperative management of endoscopic endonasal surgery. Appropriate and careful treatment of any complications is required. Preoperative management predominantly involves imaging and endocrine, visual function, eye movement, and nasal cavity evaluations. Conversely, postoperative management focuses on ensuring pituitary dysfunction, while preventing cerebrospinal fluid leakage, meningitis, and nasal complications. In addition, the method of expansion of the surgical field and skull base reconstruction to reduce postoperative complications are also important. This section explains current perioperative management strategies, focusing on the preoperative and postoperative periods, for endoscopic endonasal surgery for parasellar and midline skull base lesions.
