Endoscopic transnasal transsphenoidal treatment of pathology of the sellar region

From October 2001 to the end of November 2002 in Department of Neurosurgery, Silesian University School of Medicine in Kato-wice 70 explorations of the sella turcica were executed using the endoscopic method. In 63 cases the operation was done because of pituitary gland adenomas. In one case the diagnosis was craniopharyngioma, in 1 chordoma of the clivus, in one glioma of the optic nerve, in 1 the reason for an operation was an empty sella syndrome and in 3 cases the pathological diagnosis was an amorphous masses. Patients were operated using the 4-mm diameter endoscope with 0- and 30-degree angled lenses, using the method according to Jho and Carrau with our own modifications. In all cases of adenomas the total removal of the tumour was obtained in 71.4 %. Permanent diabetes insipidus occurred in 4.3 % of all operated. patients. In our series of patients we did not observe any postoperative CSF leak or rhinological complications. One patient died, corresponding to 1.4 % of all cases. We the recommend transsphenoidal transnasal endoscopic approach for use in the cases of sellar region pathology because of the advantages of the method for surgeon and for comfort of the patient.
