I then scrubbed back into case once Dr. X had completed removing this portion of the tumor.  There was no tumor remaining at this point.  I placed some Norian in the porus to seal any air cells, although there were no palpated.  An intradural space was then irrigated thoroughly.  There was no bleeding.  The nerve was attempted to be stimulated at the brainstem level, but it did not stimulate at this time.  The dura was then closed with 4-0 Nurolons in interrupted fashion.  A muscle plug was used over one area.  Duragen was laid and strips over the suture line followed by Hemaseel.  Gelfoam was set over this and then a titanium cranioplasty was carried out.  The wound was then irrigated thoroughly.  O Vicryls were used to close the deep muscle and fascia, 3-0 Vicryl for subcutaneous tissue, and 3-0 nylon on the skin.
