The authors report the potential shrinking of mammalian bone-derived hydroxyapatite orbital implants by osteoclastic activity, which may lead to orbital volume loss. This volume loss might affect the cosmesis and the prosthesis motility leading to a significantly reduced quality of life.2–5 However, this study did not … ER -
