a.
Measured in total admission days from the index surgery including the day of the surgical intervention.
b.
Numbers and percentage total more than 35 and 100% as several subjects had multiple new CN deficits.
c.
There were 32 lesions where resection extent was meaningful.
d.
Table 5 provides details regarding post-operative complications.
e.
HB = House- Brackmann Facial nerve grading Scale.
f.
Both subjects had clinical Neurofibromatosis type 2 and required additional interventions for other lesions.
g.
StdDev = Standard Deviation.
