Orbital volume augmentation with calcium hydroxyapatite filler in anophthalmic enophthalmos

Purpose: to report the long-term results of orbital volume augmentation using calcium hydroxyapatite filler injections in patients with anophthalmic sockets. methods: twelve eligible patients with post-enucleation socket syndrome (pess) and small orbital volumes were included in our study. in this investigation,1.5 ml injectable calcium hydroxyapatite (radiesse) was utilized in an off-label application under local anesthesia. we evaluated the effect of orbital volume augmentation for correction of enophthalmos. results: five women and seven men with a mean age of 35 years (range,21-72 years) were included in the study. the mean follow-up was 19.5 months (range,16-27 months). enophthalmos and deep superior sulcus were reduced in all patients during all follow-up visits postoperatively. the mean improvement of enophthalmos was 2.58 mm (range,1-5 mm) and the improvement in deformity grading of superior sulcus was 0.83 (range,0-4 grade). the mean marginal reflex distance increased by 0.6 mm (range of -1 to 3 mm). complications included increase in ptosis in two cases and extrusion of the filler accompanied by discoloration of the skin in one case. conclusion: the use of injectable calcium hydroxyapatite for orbital volume restoration in anophthalmic sockets is a simple,fast,and minimally invasive method with considerable long-term effects and low complications. © 2017 journal of ophthalmic and vision research | published by wolters kluwer - medknow.
