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.

A preliminary report of percutaneous craniofacial osteoplasty in a rat calvarium

“…[5][6][7] Not surprisingly, off label uses of Radiesse have arisen as well. [8][9][10] To our knowledge, no one to date has examined the histologic effects of Radiesse injection at the bony interface. We have now shown that Radiesse is biocompatible and long-lasting subperiosteally.…”

Adjunctive Use of Hyaluronic Acid Gel (Restylane Sub-Q) in Anophthalmic Volume Deficient Sockets and Phthisical Eyes

“…These patients understood that the effects were reversible and temporary and were given the option of repeating the injection or more permanent treatments when effects had begun to diminish, and they were unhappy with their appearance. Complications of the injection in this study included mild, selfresolving eyelid oedema, which has been previously reported in the literature, 12 and orbital cellulitis, which remains a complication from any invasive orbital treatment. While this is a quick Orbital volume details pre-and post-SubQ Patient Preinjection enophthalmos measurement (mm)…”

“…While the effect of this HAG did diminish over time, this study illustrates that Restylane Sub-Q can produce good results with small injected volumes. As with a previous study, 12 the authors could not directly correlate volume of HAG injected (ml) with the reduction in enophthalmos achieved (mm), which may be due to preexisiting anatomical and structural differences between the orbits injected.…”

Osteoplasty Using Calcium Hydroxylapatite Filler

“…We have successively used calcium hydroxylapatite for orbital augmentation to treat enophthalmos and superior sulcus deformity in the anophthalmic socket. 5 Herein, we report that small bony defects in the skull after surgery or trauma can easily be filled. Although these cases were performed in an ambulatory surgery center, the technique could simply be done as an office procedure with local anesthesia.…”
