Abstract:

The purpose of this study was to evaluate the results of the supraorbi tal keyhole approach performed on tumors of the anterior fossa and sellar region. Altogether 39 patients with tumors of the anterior fossa and sellar region wer e operated upon by using this approach traditional subfrontal approach were oper ated upon by and 36 patients. The surgical resu lts were analyzed prospectively and compared. It showed no difference in th e tumor resection degree, main complicatio ns and tumor recurrence between the two different approaches. But patients who w ere operated on and received the supraorbital keyhole approach had less operativ e trauma, achieving good out-looking and shorter hospitalization. It suggests t hat the supraorbital keyhole approach with a eyebrow skin incision is a safe and convenient minimal-invasive approach for experienced micro-neurosurgeons in t he treatment of lesions of the anterior fossa and sellar region.
