Study Summary
This study is being done to demonstrate the feasibility of using a nasal endoscope to perform intraoperative angiography of surgical field, with the goals to evaluate anatomical landmarks and tumor characteristics during skull base surgery and publish a technical note.
Primary Outcome
We aim to show that ICG fluorescence of the tumor intraoperatively is directly proportional to the contrast enhancement of the tumor from preoperative MRI. Enhancement is shown in ratio form on a scale of 0.01-1.00 showing enhancement ratios of 1. gland to internal carotid artery compared to blood fluorescence and 2. tumor tissue to blood fluorescence. Video recordings of intra-operative ICG fluorescence was compared to pre-operative imaging enhancements and compared in ratio format with a possi
Interventions
- DEVICE near-infrared light nasal endoscope used with ICG
