The Biopsy - What the surgeons did

Transoral Stereotactic Technique for Clival Biopsy

Sounds fancy.  basically they did lots of CT scans

The info from which was loaded in to a computer to guide the tools through the nasal passage to the Clival area where the biopsy was taken

Continuous image guidance is used
A bone biopsy instrument was advanced through the nose into the clival lesion
Bone biopsy instrumentation was placed into the clival lesion
Biopsy forceps were placed through the working channel of the biopsy instrumentation and specimen was retrieved from the clival mass

Notes:
Computed tomography (CT) is a process that images anatomic information from a cross-sectional plane of the body. Biopsy is the process of taking a sample of tissue from the body for analysis. CT is commonly used in biopsies to provide images that help guide the tools or equipment necessary to perform the biopsy to the appropriate area of the body
