Clinical Experience of the Secondary Hydroxyapatite Orbital Implant
Published Online: Jul 24, 2015
During the course of fitting prosthesis, several complications including anophthalmic enophthalmos, anophthalmic ptosis, extrusion or migration of implant and socket contracture could develop.
The hydroxyapatite sphere has been used to be a biocompatible implant after enucleation of evisceration surgery because the hydroxyapatite has been good fibrovascular ingrouwth, few postoperative complications, excellent prosthesis motility and good cosmesis.
The author used the hydroxyapatite as a secondary orbital implant in 19 eyes of anophthalmic socket patients. Good extra-ocular muscle motility & volume reconstruction after secondary hydroxyapatite implantation with retaining of peg were obtained.
Average follow-up period was 8 months ranged from 6 to 27 months.
As complications, 3 cases of wound disruption, 2 cases of loss of lower cul-de-sac were encountered.
The hydroxyapatite is suggested to be a good biocompatible implant for anophthalmic socket patients.
