Transsphenoidal surgery utilizing computer-assisted stereotactic guidance

Computer-assisted guidance technology represents the next step in the application of stereotactic techniques to skull base surgery. Use of this 3-D technique reduces operative time and complications as the technique allows a more direct approach with precise real-time anatomical guidance. We present seven cases of transsphenoidal parasellar surgery where this technique has been employed. The pathology included lesions of the sella turcica, parasellar region and the petrous apex.
