Supraorbital Foramen - Morphometric Study and Clinical Implications in Adult Indian Skulls.

ABSTRACT

Introduction: Supraorbital foramen is an important site for various surgical and anesthetic procedures. Accurate localization of the foramen holds the key to success, although racial variations exist in various population groups. Th e study included the morphometry of supraorbital foramen and its location with respect to nearby anatomical landmarks. Methods: A total of 100 dry skulls (60 male and 40 female) were collected and observed for the study. Various parameters in the sagittal and transverse planes were noted from supraorbital foramen on both sides, together with its vertical and horizontal dimensions. In addition, the location of supraorbital foramen with respect to midline and frontozygomatic suture were noted. Results: Th e study of 100 adult skulls revealed that the SON (71% on right and 70% on left) was found more frequently than the SOF (29% on right and 30% on left).Th e distance between centre of SOF/SON and midline was found to be statistically signifi cant on right and left sides. Conclusions: Th is study makes possible the identifi cation of exact position of supraorbital foramen and also discuss its racial variation.
