Background: High-speed drilling is associated with potential injury to neurovascular structures, particularly during intradural drilling of the anterior clinoid process.
Method: During an anterior clinoidectomy, a cotton patty and middle cerebral artery branches became inadvertently wrapped around the bit, causing a tear on the inferior M trunk. Following temporary clipping of the internal carotid artery, the tear was identified. Temporary clips were placed proximally and distally. The tear was then repaired with interrupted microsutures.
Conclusion: Extreme care should be exercised during clinoidectomy. Should small vascular injury occur, direct microsuturing can be a good alternative to sacrificing or implantation anastomosis repair.

"Città della Salute e della Scienza" University Hospital, Skull Base and Pituitary Surgery Unit, Turin, Italy; "Città della Salute e della Scienza" University Hospital, Neurosurgery Unit, Turin, Italy.
Purpose: To evaluate the correlation between the degrees of circumferential decompression of the optic canal (OC) and the improvement of visual acuity in patients with parasellar meningiomas (PMs) with optic canal invasion.
Methods: This is a monocentric retrospective study conducted at author's institution. The visual acuity was evaluated preoperative and at 3-months after surgery with Snellen acuity test.
Modified Lateral Supraorbital Craniotomy with Posterior Orbitotomy and Anterior Clinoidectomy for Resection of a Midline Planum and Tuberculum Sellae Meningioma.

The patient is a 51-year-old woman who had been experiencing syncope and near-syncopal events for at least 10 years with an otherwise benign neurological exam. Magnetic resonance imaging revealed an extra-axial mass consistent with a midline planum and tuberculum sellae meningioma, for which the patient opted to have resected. We demonstrate how performing a posterior orbitotomy with anterior clinoidectomy can enhance a lateral supraorbital craniotomy.

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.
How I do it-Dolenc approach for clipping of ventral wall paraclinoid ICA aneurysm.

Article Synopsis
- Ventral wall ICA aneurysms are challenging to treat due to their location near the anterior clinoid process and the complexities of preserving the ophthalmic artery and ICA during surgery.!
- A case study of a 38-year-old patient used the Dolenc approach to address this type of aneurysm.!
- The method of tailored dural peeling and extradural anterior clinoidectomy enhances access and control over the aneurysm, improving the chances of successful clipping.!
