The document discusses endoscopic transglabellar and supraorbital approaches for skull base surgery. It provides information on using these approaches to remove large macroadenomas and craniopharyngiomas. Giant craniopharyngiomas may require a combination of endoscopic transnasal and frontal or supraorbital approaches. The endoscopic supraorbital approach involves making a small incision in the eyebrow and keyhole opening to access the anterior cranial fossa.

7. Large macroadenomas with supra- or parasellar
extension that is beyond the limits of the
endonasal approach should undergo a second-
stage endoscopic supraorbital or transglabellar
approach.- Shahinian

8. In contrast, craniopharyngiomas within the pre-chiasmatic
space can be removed via a supraorbital or endonasal route,
while tumors with lateral extensions or supra-chiasmatic
extensions can be most effectively removed by a supra-
orbital or lateral transcranial approach. – from
craniopharyngioma book

Occasionally, craniopharyngiomas extend laterally beyond the midline.
Craniopharyngiomas that extend laterally are approached through the
most recent technical innovation at the Skull Base Institute, this fully
endoscopic approach involves placing an incision within the hair of the
eyebrow, performing a 1-1.5cm keyhole supraorbital opening and
advancing the endoscope along the floor of the anterior cranial fossa
underneath the frontal lobe. This approach allows a panoramic
visualization of the ipsilateral anterior fossa and a partial visualization of
the contralateral anterior fossa.
Although most craniopharyngiomas are completely resected through one
of these minimally invasive approaches, occasionally giant lesions may
require a combination of the endoscopic transnasal approach with either
the endoscopic frontal approach or the endoscopic supraorbital approach.
This can either be done simultaneously or can be staged as two separate
procedures. This allows a complete and total resection of virtually most
craniopharyngiomas from small completely intrasellar lesions all the way to
giant craniopharyngiomas extending to the suprasellar area and also
spilling laterally into the base of the anterior or middle cranial fossae.
