BACKGROUND

Age-related changes significantly affect the anatomical parameters of the orbits and facial skeleton. Transformation of the facial skeleton and orbital region structures is a complex process caused by biomechanical, hormonal and cellular-molecular factors. In this study, we will consider biomechanical changes in the orbit.

OBJECTIVE

To determine the relationship between age-related changes in the bony edges of the orbit and its numerical indicators.

MATERIAL AND METHODS

The study sample (N=285) consisted of anonymized data from computed tomography scans obtained from people aged 18 to 98 years, the sample included 82.5% women and 17.5% men. We studied the following relationships between the parameters and the patient’s age: orbital width on both sides; depth of the orbital entrance in relation to the plane of the bridge of the nose; depth of the canine fossae; angles of the superciliary arches; orbital diagonal; angles of the lateral wall of the orbit (zygomatico-orbital complex). The results of the study were processed in IBM SPSS Statistics 26 [rus] (“SPSS: An IBM Company”, USA) and Microsoft Excel 2016 Microsoft Corp., USA).

RESULTS

Significant differences were found in the diagonal of the right and left eye sockets, the depth of the canine fossa (Mann-Whitney U-test, p<0.01) and differences at the level of trends in the width of the right eye socket (U=1630.000, p=0.071) in patients of different sexes.

CONCLUSION

Increased age is associated with an increase in the width and diagonal of the orbits, which may be related to age-related changes in bone tissue, such as remodeling or deformation, and an increase in the depth of the orbital entrance from the plane of the bridge of the nose and the angles of the brow and cheekbones may reflect age-related changes in the structure of the facial skeleton, such as loss of soft tissue volume or changes in bone architecture
