OBJECTIVE To analyze long-term results and to determine prognostic factors on seizure outcome in a series of patients with temporal lobe epilepsy (TLE) who underwent anteromedial temporal lobectomy (AMTL). MATERIALS AND METHODS From 1995 to 1998 forty-two patients suffering from non-lesional TLE underwent tailored AMTL at our Institution. We(More)
BACKGROUND We report the clinical, radiological, and surgical findings of patients with posterior fossa meningiomas surgically treated at our institution over the last 6 years. METHODS We reviewed 161 consecutive cases of posterior fossa meningiomas operated on between April 1993 and April 1999 at The George Washington University Medical Center. RESULTS(More)
OBJECTIVES Comparative anatomical studies have proved to be invaluable in the evaluation of advantages and drawbacks of single approaches to access established target areas. Approach-related exposed areas do not necessarily represent useful areas when performing surgical manoeuvres. Accordingly the concept of "operability" has recently been introduced as a(More)
OBJECT Intracranial intradural chordomas are extremely rare lesions, and only a few cases have been reported in the neurosurgical literature. The authors performed a retrospective analysis of cases treated at their institutions. They present an illustrative surgical scenario and discuss the published literature, pathogenesis, and histopathological features(More)
Encephaloceles are pathological herniations of brain parenchyma through congenital or acquired osseus-dural defects of the skull base or cranial vault. Although encephaloceles are known as rare conditions, several surgical reports and clinical series focusing on spontaneous encephaloceles of the temporal lobe may be found in the otological, maxillofacial,(More)
OBJECT The authors describe a modified Le Fort I maxillotomy with medial and posterior antrectomy and removal of the pterygoid plates, aimed at improving the lateral surgical exposure during open transmaxillary surgery for pathological conditions involving the clivus. A cadaveric microanatomical study was conducted to compare the planimetric exposures(More)
The authors describe the extradural subtemporal transzygomatic (ESTZ) approach and its variants to expose the clival and paraclival areas. A microanatomical study was conducted to quantify the clival and paraclival exposure and the maneuverability areas obtained by microscope and endoscope using the ESTZ approach. Section versus preservation of the third(More)
The chordoid variant of meningioma is a histological subtype which carries with it a more aggressive clinical course and a propensity for recurrence. Similar to other meningioma subtypes, this lesion is encountered typically in the supratentorial compartment, often along the cerebral convexities. The chordoid meningioma subtype is found primarily in the(More)
The pterygopalatine fossa (PPF) is a small anatomic region of particular interest in cranial base surgery. Infectious diseases and malignancy may spread through the PPF to contiguous areas as a result of the low resistance offered by the numerous foramina and fissures that surrounds the fossa. We present an anatomic report on the PPF. Twelve sides of six(More)
BACKGROUND Cranial nerve hemangioblastomas are exceedingly rare lesions. We review available literature and present the first surgical report on a solid hemangioblastoma arising from the trigeminal nerve and involving the Meckel cave that was successfully treated with selective embolization and successive surgical resection.
