    Abstract:
    OBJECTIVE: To evaluate the clinical effect of the drilling and inserting a motility peg at the time of hydroxyapatite orbital implant. METHODS: After drilling and insertion of a titanium motility peg, a hydroxyapatite orbital implant was inserted in 31 consecutive patients. Of the 31 patients, 23 had been referred for primary enucleation and 8 for secondary implant surgery. The titanium-threaded sleeve was driven into the hydroxyapatite after which the titanium flat-headed peg was inserted into the sleeve before orbital implantation. The flat-headed peg was replaced with a titanium motility/support peg 3 to 7 months later. RESULTS: Follow-up ranged from 3.0 to 11.0 months (mean, 6.9 months). All patients were successfully fit with prostheses. Prosthetic motility was acceptable in each patient. 12 of 31 titanium flat-headed pegs became spontaneously and partially exposed within 3 to 7 months. There were no cases of secondary infection, implant exposure or extrusion of the motility peg. CONCLUSION: The hydroxyapatite orbital implant primary drilling procedure gives good cosmetic results with good motility of the artificial eye. It does not result in increased complications, and is an effective and efficient surgical option.
