Complications in motility PEG placement for hydroxyapatite orbital implant in anophthalmic socket.
OBJECTIVE
In a retrospective study, we evaluated the complications in using the motility peg system (nonsleeved and sleeved) for hydroxyapatite orbital implants in an anophthalmic socket.


METHODS
Drilling for motility peg placement was performed in 265 patients with hydroxyapatite implantation: nonsleeved peg system (n = 191), sleeved peg system (n = 74). A statistical analysis was performed using the chi-square test.


RESULTS
Extrusion rates were significantly lower in the sleeved peg system (10.8%) compared to the nonsleeved peg system (27.2%) (P =.005). The other complications related to motility peg placement were granulation tissue overgrowth (4.2%), hydroxyapatite exposure around peg head (3.0%), and decentered peg (1.9%).


CONCLUSIONS
To minimize peg extrusion, the sleeved peg was better than the nonsleeved peg for use in primary motility peg placement.
