Initial experience with gamma knife surgery for endocrine ophthalmopathy.
The aim of this study was to evaluate both the effectiveness and safety of the treatment of endocrine ophthalmopathy with gamma knife surgery (GKS). ⋯ In light of the results obtained the authors consider that GKS may be a safe and effective way to treat endocrine ophthalmopathy.

Microvascular decompression after gamma knife surgery for trigeminal neuralgia: intraoperative findings and treatment outcomes.
The authors sought to determine whether the results of trigeminal microvascular decompression (MVD) are influenced by prior gamma knife surgery (GKS). ⋯ In the authors' experience, trigeminal MVD can be performed without added difficulty in patients who have previously undergone GKS. The success rates seem similar to those normally associated with MVD. Patients who elect the less invasive option of GKS can be assured that trigeminal MVD remains a viable alternative at a later date if further surgery is required.

The effect of gamma knife irradiation on functions of striatum in rats.
An animal model has been developed to study the effect of gamma knife surgery(GKS) on cerebral function. ⋯ Targeting by using the Régis-Valliccioni frame was very accurate compared with targeting with coordinates based on brain maps used hitherto. Although targeting improved the accuracy, further effort will still be necessary to reduce errors along dorsoventral axis. The apomorphine test indicated a reduced dopaminergic function of the irradiated area including striatum, which accompanied histological changes after a high dose of irradiation (150 Gy).
