Introduction The treatment of anterior skull base neoplasms has successfully evolved over the past few decades. Conventional approaches often employ open techniques involving transfacial dissection with or without frontal, bifrontal, pterional, or orbitozygomatic craniotomies. This may allow for en bloc…
Introduction Endoscopic reconstruction following transtuberculum and transplanum approaches to suprasellar pathology is an area of ongoing evolution. The cornerstones of endoscopic repair remain similar to open surgical approaches with the aims of reestablishing separation of the cranial vault and sinonasal…
Introduction Pituitary adenomas are the most common brain tumors, with a prevalence of 10% to 15% of all intracranial tumors. Pituitary adenomas can present as hormonally active tumors with autonomous hormone secretion or, more commonly, as nonfunctioning lesions with symptoms…
Introduction Since the advent of endoscopic sinonasal surgery, we have continued to see rapid growth and expansion of endoscopic techniques used for a variety of other indications. We first began to see this demonstrated after comparing traditional transcranial approaches versus…
Introduction As endoscopic skull base surgery has evolved, the nasoseptal flap (NSF) has become the preferred vascular flap for the reconstruction of skull base defects. Similar to external approaches, the objectives of skull base reconstruction are to separate the sinonasal…
Introduction The three phases of any surgery are (1) surgical exposure (approach), (2) eradication of pathology, and (3) reconstruction. Although each phase may be performed sequentially by the same or different surgeons, they are interdependent, and the impact of each…
Introduction Computed tomography (CT) and magnetic resonance imaging (MRI) play complementary roles in the pre- and postoperative evaluation of the various neoplasms that occur at the skull base. Typically, both imaging modalities are obtained in the diagnostic workup and treatment…
Introduction Sinonasal malignancies are rare with annual incidence rates near 1 per 100,000 in most industrialized countries and represent fewer than 4% of neoplasms arising in the head and neck. , The most common malignant tumors of the anterior skull…
Introduction Sellar lesions are common and encompass a wide variety of pituitary and parasellar region pathologies. Broadly speaking, they can be categorized as neoplastic, congenital, inflammatory, infectious, and vascular causes with tumors being the most common sellar mass. In a…
