Eligibility Inclusion Criteria: - 18 years and above - Patients undergoing an an EEA for cranial base pathology that will require any of the following will be eligible for the study: optic canal decompression, intradural tumor dissection, dissection of tumor around the internal carotid artery. Exclusion Criteria: - Less than 18 years of age - History of sulfa, iodide, or penicillin allergy - Previous anaphylactic reaction to ICG - Women currently pregnant or nursing

Study Design


Intervention

Device:
near-infrared light nasal endoscope used with ICG
Using the near-infrared light nasal endoscope with ICG will identify anatomical landmarks and and tumor characteristics to provide a clear demonstration of the blood supply.

Outcome

Type Measure Description Time frame Safety issue
Primary ICG Fluorescence Ratio 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 possible score of 0.01-1.00 The higher the ratio, the more closely the intra-operative fluorescence was related to the pre-operative imaging enhancements. 1.00 is considered to have the same enhancing brightness on pre-operative imaging as intra-operative video surveillance. Before intradural dissection and during tumor dissection.
