Objective: To explore the method and efficacy of microsurgery for anterior clinoidal meningiomas.
Methods: The clinical data of 53 patients with anterior clinoidal meningiomas treated from 1991-2009 were analyzed retrospectively. There were 15 males and 38 females. The age range was 33 - 65.5 years old (mean: 45.5). All patients underwent microsurgery through pterional, extended pterional, frontotemporal, frontotemporal and orbitozygomatic approaches.
Results: Of 53 patients, total, subtotal and partial resections were performed in 38, 10 and 5 cases respectively. Postoperatively, 48 patients recovered well, 4 had mild disability, 1 severe disability and no dead case.
Conclusion: Most anterior clinoidal meningiomas can be removed safely and effectively. Several approaches may be used to achieve the best results. Microsurgical operation can offer a great aid in an effective resection of anterior clinoidal meningiomas and reduce the postoperative complications and mortality. Postoperative radiotherapy should be carried out for the residual tumor invading cavernous sinus or internal carotid artery.

Objective: The aim of this study was to synthesize existing knowledge regarding the anatomy of the cavernous sinus (CS), critically evaluate the current anatomical hypotheses concerning its walls, to conduct anatomical dissections and develop a comprehensive understanding of the connective tissue structure of the CS.
Methods: We performed systematic dissections on fifteen fresh adult cadavers. Specifically, five specimens were approached laterally, five were sectioned in the axial plane, and five were dissected using endoscopic endonasal techniques.

Background: Endoscopic transorbital approach (eTOA) has been recently proposed as an alternative skull base approach. However, its feasibility for deeper lesions can be hampered by a reduced surgical maneuverability. Aim of this study is to consider how its extension through orbital rim resection can overcome this limitation, and to compare two different techniques for its removal.

Objective: The inferior hypophyseal arteries (IHAs) are intimately related to pituitary and cavernous sinus (CS) lesions. There is still no anatomical study specifically analyzing the IHAs. The aim of this study was to investigate the surgical anatomy and variations of the IHA, and to translate this knowledge into surgical practice.

Article Synopsis
- The study investigates the transorbital approach (TO) for accessing vascular lesions, specifically the carotid and middle cerebral arteries, using cadaveric specimens to understand its feasibility for vascular clipping.
- Dissection involved a stepwise TO method that included procedures like lateral orbital craniectomy and anterior clinoidectomy, allowing for exposure of various vascular segments and cranial nerves.
- Findings suggest that the TO approach effectively exposes key artery segments, indicating its potential use in treating paraclinoid and posterior communicating aneurysms.
Surgeon versus radiologist: an inter-rater reliability analysis of the CLOSE checklist for preoperative CT sinus assessment.
Eur Arch Otorhinolaryngol

Department of Otolaryngology-Head and Neck Surgery, McGill University, Royal Victoria Hospital, Montreal, QC, Canada.
Purpose: To assess the inter-rater agreement of the Cribriform plate, Lamina papyracea, Onodi cell, Sphenoid sinus pneumatization, and Ethmoidal artery (CLOSE) checklist results among rhinology & skull-base surgeons and a head and neck-neuroradiology specialist for pre-operative computed tomography (CT) sinus assessment.
Methods: This retrospective cross-sectional study reviewed 50 patients who underwent endoscopic sinus surgery (ESS) in the period between January 2013 and March 2014 at the Royal Victoria Hospital in Montreal, Canada. According to the CLOSE checklist, the CT scans were evaluated independently by one surgeon and one radiologist using the InteleRadiology Picture Archiving and Communication System (IntelePACS).
