Objective: To investigate the clinical characteristics and causes of the patients who received an emergency reoperation involving a craniotomy after neurosurgery for skull base tumors. Materials and methods: A retrospective analysis was performed with 14 patients who underwent an emergency reoperation involving a craniotomy after received skull base surgery in the Skull Base and Brainstem Divis...

Primary extradural meningiomas presenting as scalp swelling is uncommon. Their diagnosis by fine needle aspiration is rare as majority of the lesions are hyperostotic. Primary intraosseus meningiomas involving the skull constitute only about 2% of meningiomas and are often mistaken for other primary or secondary bone tumors. The authors report a case of primary calvarial meningioma involving th...

INTRODUCTION  Meningiomas of the anterior clinoid process are uncommon tumors, acknowledged by most experienced surgeons to be among the most challenging meningiomas to completely remove. In this article, we summarize our institutional experience removing these uncommon and challenging skull base meningiomas. METHODS  We analyzed the clinical outcomes of patients undergoing surgical removal o...

Utilizing the conceptual combination of brain protective skull base surgery and minimalism, a conventional frontal craniotomy for tumors in the subfrontal and parasellar regions is modified to an orbital roof craniotomy. Through a 4 to 5 centimeter (cm) long eyebrow incision an orbital roof craniotomy (measuring 2 cm by 3 cm), including the supraorbital arch, is made as a single piece bone flap...

Introduction: Tuberculum sellae and planum sfenoidale meningiomas represent 5% to 10% of intracranial meningiomas and represent a subgroup of anterior skull base meningiomas. Approximately two thirds of patients complain of failing vision in one eye as the first symptom, and monocular blindness may be present in half of patients before surgery. Due to the constant antomical relationship of thes...
