Decoding Periorbital Aging: A Multilayered Analysis of Anatomical Changes.

BACKGROUND

Periorbital aging is a complex phenomenon that involves multiple layers of facial anatomy, including bone, fat, and globe. While previous studies have predominantly focused on age-related changes in facial fat compartments, this research aims to provide a comprehensive understanding of all periorbital components, including upper and lower orbital fat, orbital cavity volume, globe volume, and globe position, in the context of aging.

METHODS

We conducted a retrospective study involving 118 patients (236 subjects) aged 18-99 years who underwent brain MRI using a 3 Tesla MR system. Baseline demographics and various parameters pertaining to periorbital aging were collected, and comprehensive measurements were obtained through meticulous radiological analysis.

RESULTS

Our findings revealed distinct patterns of age-related changes in the periorbital region. Upper orbital fat remained stable with age, while lower orbital fat exhibited a substantial increase in both anterior and posterior compartments. Notably, orbital cavity volume expanded with bony resorption, while eye globe volume decreased, contributing to an enophthalmic appearance. We observed no vertical displacement of the globe with aging.

CONCLUSION

This study provides a comprehensive overview of the multifaceted anatomical changes that occur in the periorbital region with aging. The insights gained from this research offer important clinical implications for addressing the signs of periorbital aging, guiding surgical interventions, and ultimately enhancing patient outcomes.
