Meningo-Orbital Foramen in South Gujarat population

Abstract

Abstract Background & Aims: Meningo-orbital foramen is provides a route for an anastomosis between the meningo-orbital branch of the middle meningeal artery and recurrent meningeal branch of ophthalmic artery. Practical importance is emphasized when the middle meningeal artery has abnormal origin, in the cases of subtemporal epidural hematoma, tumors, vascular malformations and in the cases when the foramen spinosum is absent. Present study was undertaken in order to explore the frequency and positional anatomy of this foramen in ninety dry adult human skulls of south Gujarat population. Material & Method: This study was conducted on 90 dry skulls of human origin. Different parameters were noted. Result: Meningo-orbital foramen was absent bilaterally in 35[38.88%] of the skulls studied .The presence of the Meningo-orbital foramen was detected in the 55[61.11%] cases. It was present unilaterally in 30[33.33%] cases [10 on the right and 20 on the left side], and bilaterally in 25[27.77%] cases. Triple MOF were in 2 skulls on right orbit only. Largest variability was noted for distance from the lateral end of the superior orbital fissure. Conclusion: Knowledge of presence and variation in meningo-orbital foramen's anatomical parameter can be crucial for ophthalmologists and neurosurgeons.
