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)
OBJECTIVE To evaluate the clinical and radiographic manifestations of pituitary metastases (PM), discuss the role of surgery, and briefly review the pertinent literature. METHODS At a single institution between January 1992 and July 2011, 15 patients with PM were surgically treated (all cases were confirmed by histologic analysis). Of patients, 14(More)
Salivary gland tumours represent 1-4% of all human neoplasms and less than 5% occur in children and adolescents. Malignant salivary gland tumours only represent 0.08% of all childhood tumours and mucoepidermoid carcinoma (MEC) is the most common histological type. The majority of MECs in the paediatric group are histologically classified as low or(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)
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)
Cavernous sinus surgery has always been a surgical challenge because of the high functional importance of this region and the associated high morbidity. The augmented peripheral vision of the endoscope has led to the development of surgical approaches that allow adequate exposure of the cavernous sinus, with a reduction in surgical morbidity. Since 1998, 65(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)
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)
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)
