The hypothalamic region is susceptible to involvement of several processes.
Lesions in this region remain challenging for surgical access and treatment.
Strategies include both endoscopic and microsurgical approaches. A cranioorbital approach with extradural clinoidectomy and optic canal unroofing provides the necessary corridor to visualize and decompress the optic nerve/chiasm and remains an important tool in achieving complete tumor resection with favorable functional and visual outcomes. Endoscope assistance in transcranial surgery is well established, used to provide direct visualization of hidden adjacent tissues.
