[Use of endoscopy in pituitary surgery]

Endoscopy has changed many of surgical procedures concerning nasal and paranasal cavities. It has been proposed for transnasal removal of pituitary adenomas. The authors report their experience concerning four pituitary macroadenomas operated with the neurosurgical team of Sainte-Anne hospital. The endonasal trans-septal route seemed to be more anatomical and less traumatic than the rhinoseptal sublabial route. The 30 degrees rigid Hopkins endoscope was a good help for controlling the absence of any tumor remnant in the supra and parasellar regions after complete removal of the tumor performed through the endoscope or with the operating microscope. The authors discuss the advantages and limitations of such endoscopic procedures in the light of recent literature.
