•  She was a candidate for resection of this left occipital dural based tumor. After cardiac clearance, she was brought to the operating room and underwent stereotactic craniotomy and resection of the tumor utilizing stereotaxy/computer navigation and intra-operative neurophysiological monitoring.

 

After patient has undergone general anesthesia, she is placed on the operating table in prone position and computer navigation is utilized to pinpoint the tumor.

 

 

Computer navigation is utilized to pinpoint the tumor and its location is marked on the skin for planned incision and bony exposure.

After the incision is made, computer navigation is again utilized to pinpoint the tumor and its location is marked on the skull for planned bony exposure.

The bony exposure is precisely fashioned over the tumor. Here the dura is nicely exposed precisely over the tumor.

The tumor is removed utilizing ultrasonic aspirator (CUSA).

Following removal of the tumor and duraplasty, the bone is re-approximated using titanium low profile screws.

Scalp is re-approximated, patient is awakened and taken to the ICU for overnight observation.
