Abstract:

Objective  To study the relevant radial lines, the size, and the location of foramina infraorbitale, providing scientific and reasonable basic materials for clinic application.   Methods   The long and short diameter of infraorbital foramina in 60 cadavers (120 sides) were measured by ordinary vernier caliper.  The shape of the hole, the number of  accessory infraorbital holes were also record;  the distance between the infraorbital foramen and the inferior margin of the eye socket, the distance from the line between the infraorbital foramen to the anterior midline of the face were measured. The distance between the infraorbital foramen and the piriform foramen, and the distance from the line between the infraorbital foramen the piriform foramen to the anterior midline of the face were measured.   Results   The probability of foramina infraorbitale being elliptical in shape accounted for 90%, circular for 10%.  The total occurrence rate of  accessory foramen was 2.5%. The long diameter of the foramina infraorbitale ranged from 2.48 mm to7.59 mm, with an average of (4.24±0.91) mm; The short diameter of the foramina infraorbitale ranged from 1.37 mm to 3.63 mm, with an average of (2.55±0.48) mm; The distance between the foramina infraorbitale and the edge of orbital ranged from 5.16 mm to 13.63 mm, with an average of (8.54±1.60) mm;  The distance between the foramina infraorbitale and the piriform aperture ranged from 11.73 mm to 23.17 mm, with an average of (16.55±2.01) mm.  Conclusion  The study has completed the morphological data of human foramina infraorbitale, providing the scientific data for the clinical research on the foramina infraorbitale measurement.
