STUDY OF PRESENCE OF ACCESSORY INFRAORBITAL FORAMEN (AIOF) IN DRY HUMAN SKULLS OF NORTH INDIAN POPULATION

Dr. Anamika Gaharwar, Dr. Anupriya Kumar

Abstract


Introduction -IOF is a constant feature on the anterior surface of body of maxilla below the orbital margin. Infraorbital
nerve (ION) & vessels pass through it .IOF assumes great importance in the field of Maxillo- facial surgery & dentistry as
ION isanaesthetised during these procedures.
Aims & Objective: Presence of accessory IOF affects the process of nerve block as a branch of the nerve, may pass
through it. Hence a study was conducted to determine the presence of accessory IOF.
Method: The study was conducted in Department of Anatomy, G.S.V.M. Medical College, Kanpur.300 macerated dry
adult human skulls of north Indian population belonging to both sexes were selected. Numbers of accessory IOF was
determined by direct inspection.
Result: The present study found 10.7% of skulls have accessory IOF.
Conclusion: Thus knowledge of presence of Accessory IOF plays an important role in nerve block which, if ignored,
would result in anesthetic failure & injury to nerve.
