“…A study evaluating the accuracy of 3D skulls manufactured by fused deposit modelling found that the distance between nasion and the medial orbit, corresponding with the D point, was 16.85 mm and the N–Po distance had a value of 109.22 mm [ 18 ]. Although we obtained a slightly smaller value for N–D, the result was similar regarding the N–Po distance for both males and females.…”

Background: Naso-orbito-ethmoido-maxillary (NOEM) fractures are usually the result of a high or moderate intensity impact to the upper midface. These types of fractures are difficult to treat and are frequently misdiagnosed. Craniometric analysis can be of real aid in the treatment of NOEM complex fractures by establishing midfacial proportions. Aim: This study aims to establish the distances between selected anthropometric points and midfacial proportions found in the adult Caucasian population and to determine if any differences exist between genders. Methodology: Measurements between anthropometric points, nasion (N), dacryon (D), infraorbital foramen (IOF), frontomalare orbitale (FMO), rhinion (Rhi) and porion (Po), were made on 3D models obtained using patients’ CT exams. Results: Significant differences were found between genders for the orbital dimensions represented by N–FMO (p = 0.000), N–IOF (p = 0.000), Rhi–FMO (p = 0.000), Rhi–IOF (p = 0.000), nose bridge width N–D (p = 0.001), Rhi–D (p = 0.016), D–D (p = 0.038) and the projection of the nose evaluated by Rhi–Po (p = 0.000), N–Po (p = 0.000), while a t-test showed that there are no significant differences between males and females for the N–Rhi (p = 0.254). Conclusions: The values of these measurements can be utilized during skeletal reconstruction after NOEM fractures, especially for bilateral comminuted fractures where no points of comparison are available.
