Subcranial Approach: A Straightforward Approach to the Anterior Fossa Floor: 2-Dimensional Operative Video.

Indications Corridors And Limits Of Exposure: Subcranial approach is a versatile keyhole approach mainly indicated to the tumors of the anterior fossa and midline invasive tumors from the nasal cavity and paranasal sinus. 1-5 Endoscopic endonasal video assistance enhances the exposure and the safety of the approach.

Anatomic Essentials Need For Preoperative Planning And Assessment: Preoperative images depicted the size of the frontal sinuses and the relations of the lesions with frontal, ethmoid, and orbits.

Surgical strategy for intracranial dermoid and epidermoid tumors: An experience with 33 Patients.

Background: The aim of this paper is to report on our surgical strategy and technique and to identify the best management for intracranial dermoids and epidermoids tumors (IDETs).

Methods: We retrospectively reviewed 33 consecutive patients (14 males and 19 females; mean age at surgery, 37.9 years) with pathologically confirmed IDETs who underwent surgical resection, with mean follow-up of 7.

Giant clival chordoma causing pathological laughter.

Background: Chordomas are rare slowly growing tumors that originate from remnants of the notochord. They have a malignant local behavior, causing symptoms due to bone infiltration and compression of neurovascular structures. Only a few cases of brain tumors associated with pathological laughter have been reported in the literature.

Subgaleal recurrence of craniopharyngioma of rapid growing pattern.

The purpose of the present clinical case is to remind clinicians that craniopharyngiomas, which are benign neoplasms with a high incidence of local recurrences, may also present ectopic recurrences which may at first go unsuspected. These tumors most commonly arise in the suprasellar region and despite their benign histology, they may infiltrate the surrounding neurovascular structures making total removal challenging. Ectopic recurrences of craniopharyngiomas are very rare.

Cerebral biopsy: comparison between frame-based stereotaxy and neuronavigation in an oncology center.

Treatment of intracranial tumoral lesions is related to its correct histological diagnostic. We present a retrospective analysis of 32 patients submitted to 36 cerebral biopsies using neuronavigation and 44 patients using frame-based stereotaxy. Mean age was 46.

Brainstem gliomas--retrospective analysis of 86 patients.

Brainstem gliomas constitute 10% of brain tumors in children and less than 2% in adults. Since therapeutic options are limited and brainstem gliomas are associated with a high morbidity and mortality, we sought to analyze the prognostic factors associated with a better outcome. We reviewed the records of 86 patients with brainstem gliomas treated between 1996 and 2006.

Atypical facial access: an unusually high prevalence of use among patients with skull base tumors treated at 2 centers.

Objective: To analyze the influence of the unique percentage of skin carcinomas with skull base invasion on the choice of the facial surgical approach.

Design: Multi-institutional retrospective analysis of the medical charts of all patients who had undergone oncological craniofacial operations from 1981 to 2005. Data were collected on demographic distribution, location of the primary tumor, histologic type, type of operation, reconstruction, complications, and outcome.

Isolated Pathetick nerve paresis by compression from a dolichoectatic basilar artery: case report.

The article describes a woman with 53 year-old that has presented diplopia when looking down and adopted a tilted head position in order to read for the last six months. The neuro-ophthalmic examination shows isolated right superior oblique muscle paresis. The magnetic resonance and the angioresonance show the dolicoectatic basilar artery compressing the right ventral lateral brainstem.

Extensive hydromyelia.

Hydromyelia is frequently associated with dissociated sensory loss, scoliosis, and upper limb weakness. This report describes the case of a 9-year old male with an extensive hydromyelia associated with a spinal cord tumor and an oligosymptomatic clinical presentation.
