Morphology and Morphometric Study of Inferior Orbital Foramen

Abstract

The knowledge of the morphometric study of the infra orbital foramen is very much essential to prevent clinical complications during maxillofacial surgeries and regional block anaesthesia. The aim of the study is to locate the position, size and shape of the infra orbital foramen in adult human skulls of Telangana region of south India. Materials and Methods: A total of 100 dry adult human skulls of unknown age and sex were studied. The distance between infra orbital foramen and inferior orbital margin and from the foramen to the piriform aperture of the nose were measured. The vertical and horizontal diameters were also studied. Variation in shapes of the foramen and the presence of any accessory foramnina were observed. All measurements were taken with a compass transferred to callipers and analysed statistically. Results: The mean distances between the infra orbital foramen and the infra orbital margin on the right and left side were 7.9mm and 8.1mm respectively. The mean distances between the infra orbital foramen and the piriform aperture were 18.3mm and, 17.8mm on right and left sides respectively. The mean vertical dimensions on the right and left side were 3.2mm, and 3.1mm respectively. The mean horizontal dimensions on the two sides were 2.2mm and 2.3mm. Maximum number of foramina was oval in shape. Conclusion: The present study provide detailed knowledge of anatomical characteristics and clinical importance of the infra orbital foramen, which are of paramount importance for surgeons when performing maxillofacial surgery and regional block anaesthesia

Morphometric Analysis of Infraorbital Foramen in the Telangana Population

“…The vertical diameter in the present study was 3.57 ± 0.85 mm on its right side and 3. , where they reported the mean vertical diameter as 4.3 ± 0.95 mm and the mean horizontal or transverse diameter as 3.60 ± 0.84 mm. [11,[14][15][16][17] In the present study the distance from the infra orbital foramen to infra orbital margin was 7.31 ± 1.54mm on the right side and 7.27 ± 1.43 mm on the left side which were similar with the results of K K Gour et al [19,20] These values were much higher than the results of the present study.…”
