Craniometric parameters of the spatial position of the supraorbital, infraorbital and mental foramens depending on the facial index of the skull of a mature person

Keywords: craniometry, infraorbital foramen, supraorbital foramen, mental foramen


Due to increase of various operative interventions in the facial region of a mature person, it is expedient to study in detail the spatial position of the foramens of the facial part of the skull. Knowing the exact position of the foramens will help doctors during operations and minimally invasive interventions to prevent damage to the vascular and nerve bundles that pass through these foramens. The purpose of our work is to determine the craniometric characteristics and spatial position of the supraorbital (SF), infraorbital (IF) and mental (MF) foramen, depending on the type of structure of the facial part of the skull. The study was performed on 52 bone specimens of skulls and 60 CT images of adults without damage to the bone structures of the front part of the skull. Statistical methods were used to analyze the obtained measurement results in our research, which was carried out with the help of the Microsoft Excel 2010© licensed program package and with the help of the "STATISTYCA" program. When determining the position of the foramens of the facial part of the skull, first of all, we determined the individual anatomical variability of the facial part of the skull, which has the following extreme types: europrosopics (broad-faced), mesoprosopics (medium-faced), leptoprosopics (long-faced). By dividing the skulls according to the facial index, we determined the width and height of SF, IF and MF, and it was found that their diameter does not depend on the extreme types of the facial part of the skull. With the help of corresponding program, the average, lateral and line between the zy-zy points were constructed on the CT images of the 3-D models of the skulls to determine the position of SF, IF, MF relative to these lines depending on the facial index. The average values obtained were analyzed and it was established that the distance from SF, IF and MF to the median and lateral lines has larger values in europrosopics, intermediate values have mesoprosopics, the smallest results were determined in leptoprosopics. The results of the study of the distances from the above-mentioned foramens to the zy-zy line indicate an increase in their values in leptoprosopics, as opposed to europrosopics. The data we obtained confirm the dependence of the spatial position of the foramens on the type of structure of the facial part of the skull. The obtained data will supplement the craniotopographical characteristics of SF, IF and MF, and also provide a basis for further research of their position depending on the facial index.
