The authors have developed an extended transsphenoidal approach with submucosal posterior ethmoidectomy for resection of tumors located in the cavernous sinus or the suprasellar region that are difficult to remove via the conventional transsphenoidal approach. Surgery was performed using this approach in 14 patients with large pituitary adenomas, three(More)
OBJECTIVE The endoscope has recently been applied to the supradiaphragmatic transsphenoidal approach, but only case reports dealing with different pathological features have been described. The authors present their experience with this technique in 10 patients with craniopharyngiomas. METHODS A pure endoscopic endonasal technique was used. From November(More)
Odontoidectomy is the treatment of choice for irreducible ventral cervical-medullary compression. The endonasal endoscopic approach is an innovative approach for odontoidectomy. The aim of this article is to identify in which conditions this approach is indicated, discussing variants of the technique for selected cases of craniovertebral malformation with(More)
The transsphenoidal route is the most widely used technique for pituitary adenoma surgery due to its rapidity, good tolerance, effectiveness and low complication rate. These are the parameters we utilized in comparing endoscopic with microscopic transsphenoidal surgery. We reviewed the medical records of 418 patients affected by pituitary adenomas who(More)
OBJECTIVE We report our experience with endoscopic transsphenoidal or extended endoscopic transsphenoidal approaches for the treatment of cranial base lesions such as clival chordomas and chondrosarcomas. METHODS Between May 1998 and April 2004, 11 patients (four were recurrences because they previously had been treated with surgery and/or radiotherapy)(More)
OBJECTIVE In this study, the usefulness of the transsphenoidal endoscopic approach in the treatment of a Rathke's cleft cyst is reported. METHODS Between June 1998 and December 2002, 22 patients affected by sellar-suprasellar Rathke's cleft cysts were treated using a transsphenoidal endoscopic approach. Fourteen patients experienced pituitary dysfunction(More)
OBJECTIVE Purely intradural clival chordomas are rare neoplasms, and only a few cases have been reported. The reported cases present features similar to ecchordosis physaliphora, which is a notochordal remnant. We describe these 2 entities and their differential diagnoses, clinical courses, and management. This is the first reported case to be treated using(More)
OBJECT The authors compare the views afforded by the operating microscope and the endoscope in the direct endonasal extended transsphenoidal approach to the sellar, suprasellar, and parasellar regions. METHODS Five formalin-fixed, silicone-injected adult cadaveric heads were studied. A direct endonasal transsphenoidal approach was performed via the right(More)
OBJECTIVE The suitability of the endoscopic approach for the treatment of an encephalocele of the lateral wall of the sphenoid is discussed. This is a retrospective review of 4 cases diagnosed with temporosphenoidal encephalocele and having a history of CSF leak who were surgically treated using an endoscopic endonasal approach between January 2001 and June(More)
