During endoscopic endonasal transsphenoidal surgery, which of the following vascular structures is most likely to be injured?
Internal maxillary artery
Sphenopalatine artery is the answer.
The sphenopalatine artery is particularly vulnerable while enlarging the sphenoid sinus opening in the inferior and lateral direction. Once injured, it is necessary to cauterize the vessel after dissecting the mucosa off the sphenoid bone to visualize the artery clearly
The SANS Lifelong Learning Exams was designed to enhance medical knowledge and self-assessment in neurosurgery, reinforce practice patterns, and recognize knowledge gaps. SANS exams offer 250 questions across specialties worth up to 24 CME.
