Abstract

Objective To evaluate the clinical application of hydroxyapatite prosthesis in orbital reconstruction.Methods The effect of hydroxyapatite prosthesis implantation was analyzed retrospectively in 501 patients with ocular socket sunken.Under local or general anesthesia,307 cases were implanted at stage I,and 194 cases were implanted at stage II.The patients ranged in age from 2.5 to 82 years.Results The curative effects of 480 patients were satisfying.Postoperative complications occurred only in 21 patients(4.18%),which included implant exposure in 18 patients(implants were extracted in 10 cases) and conjunctival wound dehiscence in 11 patients(7 cases healed spontaneously and 4 cases were managed by secondary suture).Conclusion Without toxicity and antigenicity,hydroxyapatite is a safe material for prosthesis in orbital reconstruction.
