Aim. The aim of this study was to determine the location of the infraorbital foramen (IOF) in relation to infraorbital margin (IOM), anterior nasal spine (ANS) and Nasion (Na), Supraorbital foramen (SOF) and maxillary teeth in adult skulls (of south eastren Indian population). Material and Methods. Fourteen skulls (28 sides of skull) have been analyzed. In order to analyse the size and the relative position of the IOF with the above parameters, we have used a digital caliper for measurements with a precision of 0.01 mm. Results and Discussion. The IOF was oval in shape (85.7%) on right side and (71.4%) on left side while none of them were found either in semilunar or triangular shape in contrast to previous reports. In most of the cases IOF was found to situate lateral to the plane of SOF. The vertical and transverse diameter of the IOF on both sides was found to be almost equal. The mean distance and standard deviation (mean±SD) between right IOF and ANS, IOM and Na were 33.6±2.22 mm, 5.49±1.10 mm and 41.4±3.27 mm respectively, while the mean±SD between left IOF and ANS, IOM and Na were 33.1±2.30, 5.85±1.06 and 40.3±3.09 mm respectively. Conclusions. The results obtained from descriptive analysis are relevant for blocking the infraorbital nerve while performing surgeries in midface region, particularly in patients with edema of the infraorbital region in situation where precise location of the IOF is difficult.
