(1) Background: The transglabellar approach, a type of transfacial technique, typically involves glabellar resection and opening the frontal sinus via a bicoronal incision, providing access to the anterior cranial vault. To prevent complications, the frontal sinus is typically obliterated. However, the success of transnasal endoscopic techniques has prompted a re-evaluation of these traditional methods.

Objective: Sinonasal tumors invading anterior skull base is difficult to treat in Otorhinolaryngology and Neurosurgery. Treatment requires the collaboration of ear, nose and throat (ENT) and neurosurgeon to remove the tumor completely. This study was to evaluate the outcome of combined technique nasal endoscopic and subfrontal approach in case of sinonasal tumors involving anterior skull base.

Background: Tuberculum sellae meningiomas have an incidence from 5 to 10% of all intracranial meningiomas[2] and tend to be surgically difficult and challenging tumors given their proximity to important structures such as the internal carotid artery (ICA), anterior cerebral artery (ACA), and optic nerves.[3] Typically, their growth is posteriorly and superiorly oriented, thereby displacing the optic nerves and causing visual dysfunction, which is the primary indication for surgical treatment.[1] The main goals of the treatment are the preservation or restoration of visual abilities and a complete tumor resection.

Article Synopsis
  • Endoscopic endonasal surgery has emerged as a viable technique for accessing and treating ventral skull base lesions, especially tuberculum sella meningiomas, which are typically challenging to approach using traditional methods.
  • The endoscopic method allows for more direct access to these tumors while reducing the risk of postoperative visual decline and optic nerve injury by targeting the vascular supply early on.
  • A reviewed case highlights the importance of meticulous surgical techniques to avoid damaging key vessels, particularly the subcallosal artery, and discusses strategies for effective closure post-surgery, including the use of a lumbar drain to minimize cerebrospinal fluid leaks.

Background: Many approaches are used for midline anterior cranial fossa meningioma resection. In the subfrontal approach, the anterior superior sagittal sinus (SSS) is commonly ligated to release the anterior falx. The transbasal approach allows access to the origin of the anterior SSS, allowing for maximum venous preservation.

Despite the advances in the microsurgical technique and anatomical understanding of the anterior and middle skull base, anterior clinoidal meningiomas are still challenging lesions to resect completely and safely due to their intimate relationship with vital neurovascular structures. We report predictive factors for tumor recurrence and postoperative complications based on surgical outcome of patients with anterior clinoidal meningiomas treated at our institution.Fifty-nine consecutive patients with anterior clinoidal meningioma who were surgically treated between March, 1993, and July, 2015, were reviewed retrospectively.

Background: Different surgical approaches have been developed for dealing with third ventricle lesions, all aimed at obtaining a safe removal minimizing brain manipulation. The supraorbital subfrontal trans-lamina terminalis route, commonly employed only for the anterior third ventricle, could represent, in selected cases with endoscopic assistance, an alternative approach to posterior third ventricular lesions.

Methods: Seven patients underwent a supraorbital subfrontal trans-laminar endoscope-assisted approach to posterior third ventricle tumors (two craniopharyngiomas, one papillary tumor of the pineal region, one pineocytoma, two neurocytomas, one glioblastoma).

Aim: Midline anterior skull base meningiomas include olfactory groove meningiomas (OGMs), Tuberculum Sellae meningiomas (TSMs), and planum sphenoidale meningiomas (PSMs). The main surgical challenge in treating these lesions is to excise the tumor totally without causing mortality or morbidity. Studying the clinical patterns and the surgical outcomes of these lesions.

Object: The supraorbital eyebrow approach is a minimally invasive technique that offers wide access to the anterior skull base region and parasellar area through asubfrontal corridor. The use of neuroendoscopy allows one to extend the approach further to the pituitary fossa, the anterior third ventricle, the interpeduncular cistern, the anterior and medial temporal lobe, and the middle fossa. The supraorbital approach involves a limited skin incision, with minimal soft-tissue dissection and a small craniotomy, thus carrying relatively low approach-related morbidity.

Object: The transbasal approach (TBA) is an anterior skull base approach, which provides access to the anterior skull base, sellar-suprasellar region, and clivus. The TBA typically involves a bifrontal craniotomy with orbital bar and/or nasal bone osteotomies performed in 2 separate steps. The authors explored the feasibility of routinely performing this approach in 1 piece with a quantitative cadaveric anatomical study, and present an operative case example of their approach.

Retrochiasmatic third ventricular craniopharyngiomas are formidable tumors to remove surgically. Access to the third ventricle can be achieved through the lamina terminalis corridor. A skull base approach to the lamina terminalis can be performed using either an anterolateral approach (orbitozygomatic, pterional, supraorbital) or a midline approach (extended transbasal, subfrontal).

Objective: Anterior cranial fossa (ACF) meningiomas are difficult to surgically manage. Endoscopic transnasal approaches have increasingly been used as a minimally invasive route and thus offer significant advantages. However, a paucity of literature describing the intraoperative challenges and postoperative outcomes of this technique still exists.
