Ethmoidal dural arteriovenous fistulas (DAVFs) have a near-universal association with cortical venous drainage and a malignant clinical course. Endovascular treatment options are often limited due to the high frequency of ophthalmic artery ethmoidal supply. A 64-year-old gentleman presented with syncope and was found to have a right ethmoidal DAVF. Rather than the traditional bicoronal craniotomy, an endoscope-assisted mini-pterional approach for clip ligation is demonstrated. The mini-pterional craniotomy allows a minimally invasive approach to ethmoidal DAVF via a lateral trajectory. The endoscope can help achieve full visualization in the narrow corridor.The video can be found here: https://youtu.be/ZroXp-T35DI.

The mini-pterional craniotomy (mPT) was designed to be a minimally invasive alternative to the standard pterional (PT) approach. However, it remains unclear which technique produces better results. Thus, we aimed to perform a meta-analysis comparing functional, surgical, and aesthetic outcomes between mPT and PT in intracranial aneurysms.

Article Synopsis
- Keyhole surgical approaches for aneurysm clipping are becoming popular, yet there's limited research comparing them or guiding new surgeons in their use.
- A study involving 24 patients revealed that the mini-pterional approach (MPA) was the most common method, with some complications occurring more often in the supraorbital techniques.
- Overall, results indicate that with careful patient selection, MPA and lateral supraorbital approaches lead to excellent outcomes, although the supraorbital keyhole approach (SOKHA) presents a steeper learning curve.

Background: The locations of pituitary neuroendocrine tumor (PitNET) and anterior clinoid meningioma (ACM) appear to be very close but essentially different, as the former is inside the sella turcica while the latter is in the intradural space. A collision tumor thus requires a specific treatment strategy but has been rarely reported.
Observations: A 77-year-old woman presented with progressive visual impairment due to significant compression of the optic apparatus by a collision of PitNET and ACM.

Objective: Axel Perneczky is responsible for conceptualizing the "keyhole" philosophy as a new paradigm of minimal invasiveness within cranial neurosurgery. Keyhole neurosurgery aims to limit approach-related traumatization and minimize brain retraction while still enabling the neurosurgeon to achieve operative goals. The supraorbital keyhole craniotomy (SOKC) and minipterional (pterional keyhole, PKC) approaches have become mainstays for clipping intracranial aneurysms.

Pial arteriovenous fistulae (pAVF) are rare lesions, arising from direct fistulation between an artery and vein, with absence of a nidus. We present the surgical treatment of a 22-year-old female found to have a right middle cerebral artery (MCA) pAVF in the Sylvian fissure. The patient underwent a right mini-pterional approach, and careful dissection of the arterial feeder, venous varix and fistulation point.
