The trans-supraorbital approach is effective for gaining access to and treating supratentorial aneurysms. Also, the microsurgical field is more convenient in microscope-assisted surgery because total reliance on the endoscope is not required, and minimal brain retraction is needed. This modification of the keyhole procedure also provides multiple surgical options in this microsurgical corridor, using the principles of minimal invasiveness in cranial base surgery.

Gamma knife surgery appears to be a good, safe, and effective option for the treatment of selected hypothalamic hamartomas. No morbidity or mortality was associated with these three cases.

Object. The goal of this study was to examine the role of gamma knife radiosurgery (GKS) and adjuvant neuroendoscopic procedures by assessing the outcome in 10 patients with craniopharyngiomas who were treated between 1998 and 2001. Methods. In 10 consecutive patients (six males and four females, mean age 12 years [range 7–32 years]), there were nine mixed and one solid craniopharyngioma. In the last three cases, neuroendoscopic procedures were conducted. Two cases required insertion of an Ommaya reservoir. In another case partial removal of the cyst wall was performed using an endoscope to create a communication with the cerebrospinal pathways and thereby preclude the need for shunt insertion. Conclusions. Multimodal management of craniopharyngiomas seems to provide a better rate of survival and greater long-term disease control. It is suggested that GKS combined with adjuvant neuroendoscopy should be used as an alternative in treating recurrent or residual craniopharyngiomas if additional microsurgical removal cannot guarantee a cure.
