  • Title: Complications in motility PEG placement for hydroxyapatite orbital implant in anophthalmic socket.
    Author: Lee SY, Jang JW, Lew H, Kim SJ, Kim HY.
    Journal: Jpn J Ophthalmol; 2002; 46(1):103-7. PubMed ID: 11853724.
    Abstract:
    PURPOSE: 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.
