In rare cases, pituitary tumors cannot be removed using the endoscopic expanded endonasal approach. This situation typically occurs when the tumor has spread laterally (to the side), and therefore not reachable using the nasal corridor.
In these cases, a craniotomy may be necessary.
UCLA neurosurgeons are experienced with so-called "key-hole" microcraniotomies, in which a minimally invasive, smaller incision is hidden within an eyebrow.
