ABSTRACT

Introduction: The supraorbital notch (SON) is present at the junction of sharp lateral two-thirds and rounded medial third of supraorbital margin. The neurovascular bundle exit via this notch/foramen. The morphometric variations of the supraorbital ridge, notch, or foramen are not uncommon. The knowledge of these parameters is important to preserve the neurovascular bundle during surgery in this area.

Materials and Methods: This study included seventy skulls obtained from department of Anatomy, Doon government  medical college Dehradun and Sri Guru Ram Rai Institute of medical and health sciences Dehradun following standard guidelines. All the parameters were observed and measured with the help of vernier caliper and reported in the tabulated form.

Results: Out of seventy skulls, bilateral supraorbital notch and supraorbital foramen were found in 37.14% and 14.28% respectively. Unilateral notch and contralateral foramen was found in eight skulls i.e. 11.42%. notch or foramen was absent in 5.71% skulls. The distance from SON/F to the midline (nasion)  and frontozygomatic suture were  25.86±3.11 and 29.89±2.19 mm. respectively .  The mean distance between supraorbital notch or foramen to infraorbital foramen was 42.33 ±3.11 mm.

Conclusion: Topographical anatomy of supraorbital ridge, notch and foramen and its variation is important to prevent the complications after surgical procedure in this area.

Key words: Supraorbital Ridge, Supraorbital Foramen, Nasion, Frontozygomatic Suture.
