Unusually deep intracranial extension of instrument with internal carotid artery injury during functional endoscopic sinus surgery

Abstract

Functional endoscopic sinus surgery is a widely accepted technique, performed extensively in conjugation with septoplasty and paranasal sinus disorders, with good results and minimal complications. Even though, extreme care is required during surgery due to the proximity of the sinuses to the eyes, optic nerves, brain and internal carotid arteries. Here we report a rare case of unusually deep intracranial extension of instrument with internal carotid artery injury during functional endoscopic sinus surgery.
