Incidence and Clinical Significance of Cranio-Orbital Foramen in Telangana Region of South India

Abstract

The cranio-orbital foramen is an osseous anatomical landmark located on the postero superior aspect of the lateral wall of the orbit. This foramen is also called as meningo orbital foramen. This bony canal not always present in human skull, when it is present it contains a branch from the middle meningeal artery, providing accessory blood supply to the orbit. It is a potential source of hemorrhage during surgical procedures of the lateral wall of the orbit because it is the location of an anastomosis between the lacrimal artery and the middle meningeal artery.The purpose of this study was to determine the incidence, and number of cranio-orbital foramina in telangana population of india. Material & Methods: In the present study, 100 adult human skulls were studied at Department of Anatomy of various medical colleges present in Telangana state of south India. Results: Among 100 skulls, we found cranio orbital foramen in 57 orbits (40skulls) in which 17 skulls have bilateral foramina and 23 were unilateral. Conclusion: With the knowledge of incidence of this foramen, surgeons and ophthomologists can avoid accidental hemorrhage during surgical procedures done on the lateral wall of the orbit.

Foramen Meningo Orbitario

“…Este foramen se denomina foramen meningo orbitario (FMO) ( Fig. 1) y es un foramen propio de la órbita que permite la comunicación entre esta cavidad y la fosa craneal media, y representa un conducto embrionario entre la división supraorbitaria de la arteria estapedial y una rama de la arteria oftálmica (Georgiou & Casell, 1992;Aziz & Malik, 1997;Jhadav et al, 2012;Celik et al, 2014;Agarwall et al, 2015;Garapati et al, 2016). También se describe que en algunos casos, permitiría la comunicación entre órbita y fosa craneal anterior (Jhadav et al, 2012;Agarwall et al, 2015).…”

“…La prevalencia del FMO descrita en la literatura varía del 6 al 82,9 % en cráneos de distintos orígenes. Además este foramen se puede presentar único o múltiple y de forma unilateral o bilateral (Georgiou & Casell;Aziz & Malik;Jhadav et al, 2012;Celik et al;Agarwall et al;Garapati et al;Macchi et al).…”
