Aesthetic concerns regarding brow position
Ideal brow position is subjective, varies among facial shapes/types, and varies between male versus female
However, certain ideal norms are published
Medial brow position
Aligns with vertical line through alar base
Lateral brow position
Aligns with oblique line from alar base through lateral canthus
Horizontal positions of medial and lateral brow are equal
Apex
Aligns with vertical line through lateral limbus, which corresponds to the medial 2/3 and lateral 1/3 junction
vs aligns with vertical line through lateral canthus
Female position
Above the supraorbital rim with prominent arch
Male position
At the supraorbital rim with less prominent arch and heavier
