Summary
In men, eyebrow position relative to the eye does not significantly change with age, but deeper-set eyes correlate with a lower eyebrow. These findings aid surgical planning for the eyelid-eyebrow area.
Area of Science:
- Ophthalmology
- Anatomy
- Plastic Surgery
Background:
- The male eyebrow's topographic anatomy and its relationship with aging are not fully understood.
- Understanding eyebrow position is crucial for surgical procedures involving the eyelid-eyebrow complex.
Purpose of the Study:
- To quantify the topographic anatomy of the male eyebrow.
- To analyze the 3-dimensional relationship of the eyebrow to the eye and supraorbital rim.
- To investigate the influence of age and eye-set depth on eyebrow position.
Main Methods:
- Prospective cohort study of male patients aged 10+ undergoing ophthalmic evaluation.
- Measurements included eyebrow position relative to the pupil and lateral canthus, and supraorbital rim depth.
- Brow ptosis was assessed observationally; data underwent statistical analysis.
Main Results:
- 444 eyebrows from 222 male patients (mean age 46.75) were analyzed.
- Brow ptosis incidence was 7.4%; mean eyebrow distances (LIBD, PIBD, PSBD) were recorded.
- Eyebrow position did not significantly vary with age but correlated negatively with superior sulcus depth (deeper-set eyes had lower brows).
Conclusions:
- Male eyebrows maintain position with age, contrary to simple descent theories.
- Deep-set eyes are associated with a lower eyebrow position.
- Findings are valuable for surgical management of the eyelid-eyebrow continuum, emphasizing a 3D structural perspective.
