The meningo-orbital foramen is a small opening in the orbit lateral to the lateral end of the superior orbital fissure. It is widely reported to contain an orbital branch of the middle meningeal artery. The foramen may be single or multiple and may occur in the posterosuperior part of the lateral orbital wall or in the posterolateral part of the orbital roof. There is a lack of clarity in the literature as to whether foramina occurring in the orbital roof are the same entity as those occurring in the lateral wall. The disposition of the lesser wing of the sphenoid at the anterior limit of the middle cranial fossa makes it difficult to see how a foramen communicating with the anterior cranial fossa could transmit a branch of the middle meningeal artery. Our study contained 16 meningo-orbital foramina in the orbital roof that would transmit a fine probe. Fourteen of these passed into canals that tracked posteriorly in the bone to open into the middle cranial fossa close to the lateral extremity of the superior orbital fissure. The other two of these foramina communicated with the anterior cranial fossa and both were associated with a more posterior foramen that communicated with the middle cranial fossa. We hope this study clarifies an issue with relevance to surgery in the anterior cranial fossa.

As China’s actions have become increasingly aggressive in the Indo-Pacific, the Quadrilateral Security Dialogue’s (Quad) growing interconnectedness reveals the West’s desire to preserve the liberal order. The Quad-- composed of the United States, Australia, India, and Japan-- was revived in 2017 amidst China’s encroachment on the sovereignty of Indo-Pacific nations and international waters. Through increased activity in infrastructure development, military interoperability, and key resource networks, the Quad’s renewal marks an acceleration of Western efforts to counter China’s growing threats to Western hegemony. By distilling the Quad’s activity into these three areas of cooperation, this paper examines the grouping’s actions and their implications for Western-China relations. In the area of infrastructure development, the Quad has emphasized a diversification of funding and high-quality practices to reduce reliance on China’s Belt and Road Initiative (BRI), and has promoted democratic priorities through the formation of the Blue Dot Network (BDN). Within military interoperability, the expansion of Exercise Malabar to include all Quad nations and the decision to host the exercise in the Bay of Bengal reveals the Quad’s increased challenge to China’s encroachment on Indo-Pacific oceans. The Quad’s desire to reduce Indo-Pacific nations’ reliance on China is evident in its efforts to exert influence over key resource networks such as undersea communication cables, Covid-19 vaccines, and global supply chains. The Quad’s increased activity within these three sectors represents the grouping’s elevation to an increasingly concrete alliance, emerging as one of the West’s primary measures to counter China’s growing influence in the Indo-Pacific and beyond.
