Globe-Rim Relations
On average, the surface of the soft tissues overlying the supraorbital rim lies 10 mm anterior to the cornea, and the surface of the soft tissues overlying the infraorbital rim lies 3 mm behind the anterior surface of the cornea. This implies that the supraorbital rim usually projects 13 mm beyond the infraorbital rim.
When the orbital rims have a greater projection beyond the anterior surface of the cornea, the eyes appear deep set , when the orbital rims project less, the eyes appear prominent and round.
Negative Vector
A line or "vector" is placed between the most anterior projection of the globe and the malar eminence and lid margin. A "positive" vector relationship exists when the most anterior projection of the globe is posterior to the lid margin and the malar eminence. A "negative" vector relationship exists when the most anterior projection of the globe lies anterior to the lower lid and the malar eminence.
Reversing the negative vector
Augmentation of the infraorbital rim in patients with a retrusive infraorbital rim can bring it into a better relationship with the globe, thus reversing the negative vector.
Augmenting the orbital rim with implants is part of the strategy for normalizing the appearance in patients who have a negative vector, the implant provides support for the cheek and lid tissues.
Infraorbital implants results
This patient got Infraorbital rim implants along with a Lefort 1 to correct his midface recession. [1] [2]
