Summary: The endoscopic endonasal approach for patients with a sellar tumor is a gentle method with minimal impact on sinonasal quality of life over a period longer than six months. Common complaints post-surgery include the need to blow nose, nasal congestion, loss of smell and taste, and thick discharge from the nose. Cranial base reconstruction using muscle and fascia lata appears to positively influence sinonasal quality of life.

Summary: Considering QOL is crucial for patients undergoing endoscopic endonasal skull base surgery for skull base cancers. This review examines the different questionnaires used to assess QOL in these patients, discusses the impact of tumors and surgical approaches on QOL, and looks ahead to new techniques and tools aimed at improving QOL in patients with anterior cranial base malignancies.

Summary: This study aims to consolidate the practices and opinions of experienced skull base surgeons into a single consensus statement regarding the best practices for managing internal carotid artery (ICA) injuries during endoscopic endonasal surgery (EES) through a Delphi survey. The final consensus statement included 36 guidelines grouped under 4 categories, covering preoperative management, hemorrhage control, definitive management, pharmacologic treatment, blood pressure, and neurophysiologic monitoring.

Summary: The objective of this study is to demonstrate the safety and efficacy of the endoscopic endonasal approach (EEA) for skull base surgery in pediatric patients through descriptive analysis of cases over an 11-year period. The study included 94 patients undergoing EEA for skull base surgery, with 130 surgeries performed. The results showed that EEA is a safe and effective method for treating anterior cranial base disease in pediatric patients.

Summary: This study evaluates the usefulness of intraoperative magnetic resonance imaging (IO-MRI) in skull base chordoma surgery. The results show that IO-MRI can show the degree of resection, evaluate the volume and location of residual tumor, and improve the life expectancy of patients.

Summary: Post-operative CSF leak remains the major drawback of Endoscopic Endonasal Approach (EEA), with different reconstructive strategies being proposed to reduce its rate. Analysis of 521 patients undergoing EEA surgery showed that intra-operative CSF leak grade was associated with post-operative CSF leak rate, with higher risk in cases of IHFL. Multilayer reconstruction with fat and naso-septal flap were effective in reducing CSF leak in high-risk patients. Additionally, a significant decreasing trend in yearly post-operative CSF leak rate was observed.

Summary: This study analyzed the clinical outcomes of patients with lesions involving the petrous apex who underwent endoscopic endonasal approach and transorbital approach surgeries. The authors found that the endoscopic endonasal approach was suitable for lesions in all three zones of the petrous apex, while the transorbital approach was effective for superior portion lesions. Surgical treatment resulted in complete tumor resection and eradication of petrous apex cephalocele, but there were also potential complications.

Summary: Clival chordomas are locally invasive midline skull base tumors arising from remnants of the primitive notochord. Several intraoperative image guidance modalities have been introduced as adjuncts to endoscopic endonasal surgery, including stereotactic neuronavigation, intraoperative ultrasound, intraoperative MRI, and intraoperative CT. In this case report, we discuss the benefits of employing a novel minimally invasive side-firing ultrasound probe as a cost-effective and time-efficient option to navigate the anatomy of the paraclival region and guide endoscopic endonasal resection of a large complex clival chordoma.

Summary: An anatomical study showed that safe removal of 21%, 46%, and 27% of the anterior clinoid process can be achieved via a stepwise technique, with a cumulative removal of 94% at the end of step 3. The benefits of further removal must be balanced against the significant risks involved.

Summary: The study suggests that the endoscopic expanded endonasal approach (EEEA) can reduce the in-hospital costs for patients with anterior skull base meningiomas compared to the open transcranial approach.

Summary: Skull base chordomas (SBCs) are rare malignant bone tumors. Endoscopic endonasal surgeries (EESs) have been increasingly used for resecting SBCs. Establishing a surgical strategy based on the tumor growth directions helps improve the gross total resection (GTR) rate and achieve better outcomes in patients with SBCs.

Summary: The study found a strong correlation between gland/blood fluorescence ratios to gland/ICA SI in pituitary adenoma, as well as tumor/blood fluorescence ratios to tumor/ICA SI in various pathologies. ICG fluorescence was able to assess perfusion in pituitary gland and nasoseptal flaps, as well as visualize surrounding vasculature.

Summary: The aim of this study was to find reliable landmarks to identify the oculomotor triangle (OCMT) during the endoscopic endonasal transoculomotor approach (EETA) and protect the internal carotid artery (ICA) from injury. The study found that the clinoid-to-vidian line (CVL) and the sagittal paraclival line (SPL) are reliable anatomical landmarks that can help surgeons avoid inadvertent injury to the ICA.

Summary: The study found limited utility of 5-aminolevulinic acid (5-ALA) fluorescence in the majority of endonasal skull base surgeries, although other pathology may be worth investigating, with the possible exception of meningiomas.
