Abstract
Background: Facial aging is a dynamic process involving the aging of soft-tissue and bony structures. In this study, the authors demonstrate how specific bony aspects of the mandible change with age in both genders and what impact these structural changes may have on overall facial aesthetics. Methods: Facial bone three-dimensional computed tomographic scans were obtained from 120 Caucasian subjects (60 women and 60 men). Our study population consisted of 20 male and 20 female subjects in each of three age categories (20 to 40, 41 to 64, and ≥65 years). Edentulous patients were excluded. The following measurements were obtained: bigonial width, ramus breadth, ramus height, mandibular body height, mandibular body length, and mandibular angle. The data were analyzed with one-way analysis of variance and two-tailed t tests, with results considered significant at a value of p < 0.05. Results: There was no significant change with regard to bigonial width or ramus breadth across age groups for either gender. Ramus height, mandibular body height, and mandibular body length decreased significantly with age for both genders, whereas the mandibular angle increased significantly for both genders with increasing age. Conclusions: These results suggest that the bony elements of the mandible change significantly with age for both genders and that these changes, coupled with soft-tissue changes, lead to the appearance of the aged lower third of the face.
