What does the endoscopic transsphenoidal resection procedure involve?

This is a minimally invasive neurosurgical technique used to remove pituitary tumors and certain skull base lesions. A high-definition 3D endoscope is inserted through the nasal cavity and sphenoid sinus, allowing the surgeon to access the sella turcica without any external incisions or visible scarring. The 3D visualization provides enhanced depth perception for precise tumor removal while preserving surrounding healthy tissue.
