Gamma knife surgery for hypothalamic hamartomas accompanied by medically intractable epilepsy and precocious puberty: experience in Mexico.

Object: Hypothalamic hamartoma is a nonneoplastic malformative mass of neurons and glia in the region of the hypothalamus. Because of its location, open surgery is associated with high morbidity and mortality rates. Gamma knife surgery (GKS) may be an efficient and safe treatment approach, which produces little morbidity.

Multimodal management of craniopharyngiomas: neuroendoscopy, microsurgery, and radiosurgery.

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.

Trans-supraorbital approach to supratentorial aneurysms.

Objective: The trans-supraorbital approach has the advantage of combining the keyhole principle with cranial base surgery. The anatomic fields that can be visualized with the use of this procedure have been demonstrated in cadavers, and the advantages and potential surgical applications of this procedure are described in this report. This article is the first to describe a group of intracranial supratentorial aneurysms.
