Objective: This research was aimed at telling the anatomical characteristics of the accessory supraorbital foramen (ASOF) in relation to the main supraorbital foramen (SOF), which is necessary in clinical situations that require regional surgical procedures.

Methods: A total dedicated to the presence and location of 72 dry Indian adults of unknown age and sex were investigated. In each skull, the ASOF location was measured on both sides with a Vernier caliper metal case, with the SOF as the reference point. The total number of accessory foramen was also noted.

Results: Accessory infraorbital foramens (IOFs) were seen only in 4.16% in our study and all seen were single in number. Half of those accessory foramen were present on medial and rest half were present on superomedial position as compared to the main IOF. Half among present accessory foramens were located at a distance of <2 mm and half were located at a distance of more than 2 mm. The mean location of accessory IOF was at 7.07 mm from main IOF.

Conclusion: Knowledge of the anatomical characteristics of ASOF can have major effects on surgical and local anesthetic preparation blockage of the super orbital nerves. Additional guidance for surgeons may be provided with information on the foramens obtained from this study. The surgeons should note this during the nerve block as damage to either branch will lead to sensory impairment and incomplete blocking of the nerve.
