Objective  While the endoscopic endonasal approach (EEA) has gained widespread acceptance for the resection of clivus chordomas, conventional transcranial approaches still have a crucial role in craniocervical junction (CCJ) chordoma surgery. In repeat surgery, a carefully planned treatment strategy is needed. We present a surgical treatment plan combining an EEA and a far-lateral craniotomy with endoscopic assistance (EA) in the salvage surgery of a recurrent CCJ chordoma. Case Presentation  A 37-year-old woman who had undergone partial resection of a chordoma extending from the mid-clivus to the CCJ...

Introduction  The endoscopic endonasal approach (EEA) might seem an "unnatural" route for intradural lesions such as meningiomas. The aim of this study is to critically revise our management of anterior skull base meningiomas to consider, in what cases it may be advantageous. Material and Methods  Each consecutive case of anterior skull base meningioma operated on through an EEA or combined endoscopic-transcranial approach at our institution, between 2003 and 2017, have been included. Tumors were classified on the basis of their location and intra or extracranial extension...

The optimal treatment for skull base chordomas is gross total resection followed by radiotherapy and not radiation of partially resected tumors. Supratotal resection, defined as removal beyond all involved bone and dura, is ideal but difficult to achieve. In this video, we present the case of a 37-yr-old man with new onset of progressive cranial nerve sixth palsy and a skull base lesion compatible with clival chordoma. He underwent partial surgical resection at an outside institution via transcranial approach, with significant tumor residual at the clivus, dorsum sella, posterior clinoids, and petrous apex, extensive dural invasion, and intradural extension with attachment to the basilar artery and its long perforating branches...

Nasal chondromesenchymal hamartoma (NCMH) is a rare benign tumor of the sinonasal tract in children with possible orbit and skull base involvement. We present the 57th published observation of this kind of tumor. A 25-month-old female patient presented with recurrent mass lesion of the sinonasal tract. According to her history, she had feeding difficulties and nasal obstruction since birth. She underwent partial resection at eight months of age via transfacial approach in the local hospital. Due to progression of tumor remnants, a second surgery was performed using an endoscopic endonasal approach resulting in subtotal resection...

BACKGROUND: Endoscopic endonasal surgery (EES) is increasingly used for olfactory groove meningiomas (OGMs). The role of EES for large (≥4 cm) or complex OGMs is debated. Specific imaging features have been reported to affect the degree of gross total resection (GTR) and complications following EES for OGMs. The influence of these factors on transcranial resection (TCR) is unknown. OBJECTIVE: To examine the impact of specific imaging features on outcome following TCR to provide a standard for large and endoscopically less favorable OGMs against which endoscopic outcomes can be compared...

A 52-yr-old woman was referred to a tertiary medical center for evaluation of 2 yr of progressive visual symptoms and 1 yr of retro-orbital pressure. Her ophthalmologic exam was unrevealing except for mild asymmetrical impairment in color perception. A gadolinium contrast-enhanced magnetic resonance image of the head showed a left extraconal orbital apex lesion consistent with cavernous hemangioma. Computed tomography reveled bony remodeling of the medial-inferior orbital walls with superior orbital fissure expansion...

Chondrosarcomas of the skull base are malignant tumors for which surgery is the primary therapeutic option. Gross-total resection has been demonstrated to improve survival in patients with these tumors. Chondrosarcomas arising from the petroclival synchondrosis harbor particularly unique anatomical considerations that have long been a barrier to achieving such a resection. Endoscopic endonasal transpterygoid approaches have been recently used to gain improved access to such lesions; however, these approaches have classically relied on a medial to lateral transclival trajectory, which provides limited exposure for complete resection of lateral disease...
