Skull Base Tumors
Skull base tumors arise from the cranial base or reach it, either from an intracranial or extracranial origin. A diverse group, these tumors present unique management challenges because of their relative rarity, typically deep location, close proximity to critical neurovascular structures, and extension beyond classically taught anatomic and specialty boundaries. Management outcomes for skull b...
متن کاملExtended Transbasal Approach to Skull Base Tumors
A variety of novel surgical approaches have been developed in recent years to manage disease of the cranial base. Few offer the width and depth of exposure achievable with the extended transbasal approach. This approach combines a bifrontal craniotomy with an orbitonasal or orbitonasoethmoidal osteotomy, and potentially a sphenoethmoidotomy to provide broad access to malignancies of the anterio...
متن کاملSkull Base Tumors: A Kaleidoscope of Challenge
Resection of skull base lesions has always been riddled with problems like inadequate access, proximity to major vessels, dural tears, cranial nerve damage, and infection. Understanding the modular concept of the facial skeleton has led to the development of transfacial swing osteotomies that facilitates resection in a difficult area with minimal morbidity and excellent cosmetic results. In spi...
متن کاملRevascularization for complex skull base tumors.
We discuss revascularization techniques for complex skull base lesions utilizing high-flow arterial bypass. At present, the radial artery is the donor graft utilized in most circumstances at our institution. The knowledge of revascularization techniques is very important to achieve radical resection in lesions where arterial compromise is documented.
متن کاملMalignant tumors of the anterior skull base.
BACKGROUND Cancers of the paranasal sinuses or nasal cavity are the most common malignant tumors of the anterior skull base. Several types of tumors occur in this location, including cancers of endodermal, mesodermal, and epidermal origins. Although anterior skull base surgery is a relatively recent approach in treating these tumors, widespread changes have already occurred in procedural method...
