“…Additionally, tumor capsule devascularization was recently proposed as a technique to improve tumor control and thereby limit their growth . With less aggressive surgery, most deficits are self‐limited, with most patients showing signs of improvement 3 months after surgery, followed by a return to the preoperative baseline or continuous long‐term improvements …”

“…For subtotal resections, regardless of the selected approach, studies have noticed that significantly favorable postoperative outcomes are associated with younger patients, primary tumors, and tumors <4 cm without evidence of posterior circulation encasement . However, it should be noted that patients who were eligible for resection with “less invasive” techniques such as EEA tend to have slightly greater postoperative functional improvement and lower complication rates as opposed to patients whose tumors were resected through lateral or combined surgical routes …”

“…Similarly, this can result in brainstem edema on T2‐weighted MRI. Pirayesh et al . showed that the presence of arachnoid plane was associated with 80% of gross total resection cases, whereas in 88% of the cases with near total resection, the latter was absent.…”

“…The most common complication of surgery involves CN deficits, occurring in up to 44% of the cases regardless of the selected approach, with extraocular muscle deficits being the most frequently encountered complication . Depending on the series, an overall rate of new postoperative cranial neuropathies was observed in up to 53.1% of the cases, whereas 33.3% presented with worsening of preoperative diplopia, with 72% of patients presenting during the immediate postoperative period, becoming permanent in 17% …”

Background Endoscopic skull‐base surgery (ESBS) is employed in the management of diverse skull‐base pathologies. Paralleling the increased utilization of ESBS, the literature in this field has expanded rapidly. However, the rarity of these diseases, the inherent challenges of surgical studies, and the continued learning curve in ESBS have resulted in significant variability in the quality of the literature. To consolidate and critically appraise the available literature, experts in skull‐base surgery have produced the International Consensus Statement on Endoscopic Skull‐Base Surgery (ICAR:ESBS). Methods Using previously described methodology, topics spanning the breadth of ESBS were identified and assigned a literature review, evidence‐based review or evidence‐based review with recommendations format. Subsequently, each topic was written and then reviewed by skull‐base surgeons in both neurosurgery and otolaryngology. Following this iterative review process, the ICAR:ESBS document was synthesized and reviewed by all authors for consensus. Results The ICAR:ESBS document addresses the role of ESBS in primary cerebrospinal fluid (CSF) rhinorrhea, intradural tumors, benign skull‐base and orbital pathology, sinonasal malignancies, and clival lesions. Additionally, specific challenges in ESBS including endoscopic reconstruction and complication management were evaluated. Conclusion A critical review of the literature in ESBS demonstrates at least the equivalency of ESBS with alternative approaches in pathologies such as CSF rhinorrhea and pituitary adenoma as well as improved reconstructive techniques in reducing CSF leaks. Evidence‐based recommendations are limited in other pathologies and these significant knowledge gaps call upon the skull‐base community to embrace these opportunities and collaboratively address these shortcomings.

“…The treatment is very difficult due to its location that involves the central region of the basis cranii [1]. At present, exairesis is still the best treatment option for petroclival meningioma, and the extent of exairesis will directly affect the prognosis and survival time of the patients [2]. Therefore, the best choice is to remove the tumor completely, and try to avoid or reduce the incidence of postoperative complications hence, improving patients' life quality.…”

Objective: To investigate the effect of preoperative embolization combined with Kawase approach in the treatment of petroclival meningioma. Methods: Retrospective analysis of 15 cases of preoperative embolization combined with Kawase approach surgical treatment of petroclival meningioma, and 15 cases of patients without preoperative embolization were treated as controls. The surgical difficulty, intraoperative blood loss and operation time of two groups were tested. Result: The average blood loss of the preoperative embolization group was (315.52 ± 58.71 ml), the average blood transfusion was (185.35 ± 46.15 ml), the average operation time was (2.52 ± 0.59 h). The mean blood loss was (1136.25 ± 8.26 ml), and the average blood transfusion was (488.63 ± 62.32 ml), the average operation time was (5.15 ± 1.26 h) in the non-embolization group. The differences between the two groups were statistically significant (P<0.05). The degree of tumor resection in the preoperative embolization group was significantly higher than that in the non-embolization group. Conclusion: Preoperative embolization can significantly reduce intraoperative blood loss, operation time, and decrease the difficulty of Kawase approach surgery.
