Abstract

Aims: 1. To study the morphometric dimensions of infraorbital foramen. 2. To compare the differences with other populations. 3. To study its clinical implications. Settings and Design: The data was collected from various  medical colleges in Chennai.it was an observational study. Methods and Material: Total of 257 (514 sides) dry human adult skulls of unknown age and gender were assessed. The data was collected with help of Vernier caliper, scale, needle & compass. The measurements were performed onthe right and left side of the skull. The study was conducted and the distances were analyzed of infraorbital foramen (IOF) with respect to the infraorbital margin (IOM), supraorbital foramen (SOF), nasion, the nasal rim, the superior alveolar margin (SAM) and the distance from the opposite infraorbital foramen. The height and width of the IOF was also measured. The direction of the infraorbital canal was also noted.The mean and the range was observed and compared with other populations. The data were analyzed statistically. Statistical Analysis used: SSPS. Results: Mean distances of IOF to Superior orbital foramen [SOF] are 40.2mm and 40.6mm, IOF to Nasion [N] are 42.9mm and 42.8mm, IOF to Nasal Rim [NR] are 16.3mm and 16.4mm, IOF to Infraorbital Margin [IOM] are 7.0mm and 6.9 mm, IOF to Superior Alveolar Margins [SAM] are 25.5mm and 25.4mm on the right and left side respectively. The mean distance of the IOF of one side to the opposite IOF was 50.58mm. Average height & breadth of IOF was3.85mm and 3.65mm on the right and left side respectively. These values were statistically analyzed and also compared with other populations. Conclusions: This analytical study gives detailed information of IOF which will facilitate professionals to ascertain the neurovascular bundle and in turn assist in noninvasive & invasive surgical repairs.
