Surgical Effect of the Secondary Implantation of Hydroxyapatite

ABSTRACT

Intraorbital hydroxyapatite implant has advantages such as nondisplacement, prolapse and good prosthetic motility. The surgical effect of the secondary implantation of hydroxyapatite sphere was evaluated for 18 anophthairnic sockets of 18 patients. After follow-up period of over 6 months, extraocular muscle motility, prosthesis motility, improvement of the superior sulcus deformity, and enophthalmos were evaluated. Postoperative good EOM motility was noted in 7 cases (43.8%). Of the 15 cases without drilling, good prosthetic motility was noted in I case (6.7%), fair in 3 cases (20.0%), and poor in 11 cases (73.3%). One of the two eyes with drilling had good motility and the other one eye showed fair prosthetic motility. Superior sulcus deformity and enophthalinos improved in 12 cases-(75%) and 14 cases (82.4%). In postoperative complication, displacement or prolapse of the implant was not noted in any patient. and one patient. with postradiation showed m.inimal wound dehescence with spontaneous healing.
