Abstract |
Vascularization of the hydroxyapatite sphere is important for many advantages of hydroxyapatite implant. If the rate of vascularization can be increased, the motility hole can be drilled earlier and rapid cosmetic effect and stability can be achieved. Hydroxyapatite orbital implantation procedure for earlier vascularization of the hydroxyapatite ws modified. Twenty-eight patients received modified hydroxyapatite implantation after enucleation and the graft vascularization was evaluated, at various intervals after implantation, with bone scintigraphy. The patients were divided into group I(the interval was 1 month after implantation) 12 eyes, group II(2 months after implantation) 7 eyes, and group III(4 or more months after implanation) 9 eyes, In group I, Perry grade 2 or more was achieved in 11 eyes(91.7%) and mean spect ration was 2.97. In group II and III, Perry frade 2 or more was achieved in 7 eyes(100%), 8 eyes(88.9%) respectively, and mean spect ration was 3.34. and 4.34. We found that there wasearlier vascularization of hydroxyapatite after modified hydroxyapatite implantation. So we expect more rapid cosmetic rehabilitation of the patients with modified hydroxyapatite implantation. |
