ABSTRACT
BACKGROUND: The anterolateral (juxtacondylar) approach with limited mastoidectomy is a suitable option to expose the postero-inferior part of the jugular foramen (JF). It is particularly indicated for tumors extending in the neck beyond the jugular foramen, especially in those cases necessitating both neck control as well as control of the mastoid segment of facial nerve. METHOD: We describe here the steps to safely perform an anterolateral approach with mastoidectomy along with a brief description of its indications and limits. CONCLUSION: This approach represents a valid option to reach the JF. Its knowledge can improve the process of optimal approach selection when dealing with complex pathology involving the JF.

BACKGROUND AND PURPOSE: MCA aneurysms are still commonly clipped surgically despite the recent development of a number of endovascular tools and techniques. We measured clinical uncertainty by studying the reliability of decisions made for patients with middle cerebral artery (MCA) aneurysms. MATERIALS AND METHODS: A portfolio of 60 MCA aneurysms was presented to surgical and endovascular specialists who were asked whether they considered surgery or endovascular treatment to be an option, whether they would consider recruitment of the patient in a randomized trial, and whether they would provide their final management recommendation. Agreement was studied using κ statistics. Intrarater reliability was assessed with the same, permuted portfolio of cases of MCA aneurysm sent to the same specialists 1 month later. RESULTS: Surgical management was the preferred option for neurosurgeons (n = 844/1320; [64%] responses/22 raters), while endovascular treatment was more commonly chosen by interventional neuroradiologists (1149/1500 [76.6%] responses/25 raters). Interrater agreement was only "slight" for all cases and all judges (κ = 0.094; 95% CI, 0.068-0.130). Agreement was no better within specialties or with more experience. On delayed requestioning, 11 of 35 raters (31%) disagreed with themselves on at least 20% of cases. Surgical management and endovascular treatment were always judged to be a treatment option, for all patients. Trial participation was offered to patients 65% of the time. CONCLUSIONS: Individual clinicians did not agree regarding the best management of patients with MCA aneurysms. A randomized trial comparing endovascular with surgical management of patients with MCA aneurysms is in order.

BACKGROUND: Recognition of the right surgical cleavage plane of a vestibular schwannoma is mandatory to preserve the facial nerve function. METHOD: We describe here our surgical technique that is focused on soft tissues preservation and on subperineural dissection, avoiding direct exposure of the acoustico-facial complex in order to preserve facial nerve function. CONCLUSION: Soft tissue dissection helps in reducing patient's postoperative discomfort. Meticulously keeping a subperineural plan of dissection enables to preserve facial nerve function while offering satisfying resection rates.

BACKGROUND: The optimal management of petroclival meningiomas (PCMs) continues to be debated along with several controversies that persist. METHODS: A task force was created by the EANS skull base section along with its members and other renowned experts in the field to generate recommendations for the management of these tumors. To achieve this, the task force reviewed in detail the literature in this field and had formal discussions within the group. RESULTS: The constituted task force dealt with the existing definitions and classifications, pre-operative radiological investigations, management of small and asymptomatic PCMs, radiosurgery, optimal surgical strategies, multimodal treatment, decision-making, and patient's counselling. CONCLUSION: This article represents the consensually derived opinion of the task force with respect to the management of PCMs.
