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)
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)
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 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 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 Atlantoaxial instability and odontoid invagination may occur in Down syndrome. The treatment of this lesion may require an odontoidectomy. In similar circumstances, a transoral procedure may be hampered by a macroglossia which is part of Down syndrome. In a situation occurring in an 11-year-old child affected by atloaxial instability and os(More)
OBJECT Transnasal endoscopic (TNE) approaches have been proposed for the resection of anterior cranial base meningiomas. The purpose of this article was to evaluate the results of endoscopic resection of anterior cranial fossa meningiomas by reviewing available published data in addition to the authors' experience with 13 cases. METHODS The literature was(More)
