Outcomes

Primary Outcomes

Facial nerve correlation of Fluorescein Sodium With Electrostimulation

Surgeon assessment of fluorescence correlation with electrostimulation using a Likert-style rating from 1-4 where 1=No correlation; 2=Some correlation; 3=Good correlation; 4=Excellent correlation

Time frame: Intraoperative

Correlation of Fluorescein Sodium With Surgeons' Visual Assessment of nerve

Survey of surgeon visual assessment of nerve under white light compared to fluorescence using a Likert-style rating from 1-4 where 1=No correlation; 2=Some correlation; 3=Good correlation; 4=Excellent correlation.

Time frame: Intraoperative

Ratio of Nerve Fluorescence compared to Background Tissue

Ratio of nerve fluorescence intensity compared to background fluorescence intensity

Time frame: Intraoperative

Secondary Outcomes

Average Dose of Sodium Fluorescein Administration

Average dose of sodium fluorescein administered in mg/kg

Time frame: Intraoperative

Time to Nerve Visualization

Amount of time (in minutes) to nerve fluorescence after sodium fluorescein adminstration

Time frame: Intraoperative
