A quantitative analysis of periorbital aging with three-dimensional surface imaging

Area of Science:

• Aesthetic Medicine
• Gerontology
• Medical Imaging

Background:

• Traditional facial aging studies are subjective and observational.
• This research utilizes advanced facial imaging and 3D modeling for objective aging analysis.
• Focuses on quantitative measurement of volume changes in the aging periorbital region.

Purpose of the Study:

• To quantitatively measure age-related volume changes in the female periorbital region.
• To establish objective markers for facial aging beyond subjective clinical assessment.

Main Methods:

• Acquired 3D image data from 83 individuals across 42 mother-daughter pairs (ages 15-91).
• Confirmed facial similarity using best-fit analyses.
• Measured periorbital tissue volume differences between mothers and daughters to assess aging effects.

Main Results:

• Demonstrated consistent soft tissue volume loss and regression in the medial canthus and nasojugal groove of older individuals.
• Quantified tear trough volume differences from 0.02cc to 1.27cc (median 0.38cc-0.42cc).
• Measured volume differences in adjacent periorbital tissues.

Conclusions:

• 3D imaging confirms predictable atrophy and regression of medial canthus and nasojugal groove soft tissues.
• Greatest soft tissue atrophy observed in the medial canthal region and inferior to the lower eyelid.
• Volumetric analysis of tissue atrophy is valuable for accurate periorbital rejuvenation.
