Injectable Calcium Hydroxylapatite for Orbital Volume Augmentation

Abstract

Injectable calcium hydroxylapatite provides a new, safe, simple, cost-effective technique to treat volume deficiency in the anophthalmic orbit. Augmentation achieved with this semipermanent filler has demonstrated a lasting effect in the orbit of 1 year or more with little volume loss. The filler seems to last longer in areas with less movement, blood supply, and lymphatic drainage. Injection can even be performed in an office setting using local anesthesia. The amount of volume replacement can be titrated, and the procedure is repeatable until adequate volume is obtained.
