Abstract
|
|
|
Thirteen patients received a coralline hydroxyapatite sphere as a buried integrated ocular implant after enucleation surgery. The implant was modified by multiple drillings, 1 mm in diameter, to the center of the sphere to allow more rapid host
tissue
ingrowth. 99mTc-MDP planar and tomographic bone scintigraphies were performed at various intervals after implantation (from 100 to 742 days after operation) to assess vascularization of the implant. All patients showed hot uptakes in the
implants.
These patients underwent a secondary drilling for the final motility peg application. The confirmation of vascular ingrowth was done by inspection of bleeding at the time of bleeding at the time of drilling from the center of the implant.
Bleeding
from
the drilled implant was noted in all patients.
In cnclusion, hot uptake in the implanted ocular hydroxyapatite implant accurately reflect vascular ingrowth into the implant.
