Study of Incidence and Topography of Meningo-Orbital Foramen Along With Clinical Implications

There are umpteen numbers of openings in the orbit including meningo-orbital foramen, which transmits meningo-lacrimal artery, which may be injured during orbital surgery. Aim of the study is to elaborate the incidence and location of meningo-orbital foramen and associated clinical significance. The study was conducted in the Department of Anatomy using 120 skulls of unknown age and sex. The MOF was inspected for the presence, number, and patency was confirmed by passing a probe through the said foramen. The incidence of these foramen was calculated using IBM SPSS software, version 25, Chicago, USA. A different classification is proposed. The meningo-orbital foramen was observed in 32.5% of orbits. The overall incidences of single, double, triple, and quadruplet foramina were 21.7%, 5%, 1.7%, and 0.4%, respectively. The number of these foramina ranges between 0 and 4. The information provided in this study will be of utmost use for ophthalmologists, neurosurgeons operating in orbital region, radiologists to avoid misinterpretation of radiographs, and anthropologists for identifying population.
