Implant Infection in Porous Orbital Implants

Abstract

Implant infection is a serious problem that requires additional patient visits, intensive antibiotic therapy, surgery, or some combination of these. Existence of a peg system appears to play a role in implant infection. Infection may develop as late as 6 to 7 years after pegging, and the patient should be cautioned about potential late-onset problems. It is possible to control the infection with appropriate antibiotic therapy; removal should be reserved for refractory cases.

Persistent socket pain postenucleation and post evisceration: a systematic review

“…Porous implants permit fibrovascularisation what -by providing host blood supply to the implanttheoretically serves as defence mechanism (Jordan et al 2004a;Karslo glu et al 2006). Two of the four patients developed infection after drilling procedures, and one patient had multiple ocular surgeries after implant placement.…”

“…Infection of the orbital implant is rare, and frequencies are reported to range from 0% to 5% (Jordan & Bawazeer 2001;Jordan et al 2004b;Karslo glu et al 2006;Shields et al 2007). Major presenting symptoms are discomfort, extensive discharge, conjunctival redness and also foul odour discharge.…”

Repair of orbital bone defects in canines using grafts of enriched autologous bone marrow stromal cells

“…The above artificial materials act as non-absorbable foreign bodies and have been associated with infection and extrusion, as well as cyst formation [1-3]. Although considered as the ‘gold standard’ for bone defect repair, autologous and allogenous bone grafting is limited by certain disadvantages, such as donor site morbidity, pathogen transfer, and long recovery period [4,5].…”

Remove, rotate, and reimplant: a novel technique for the management of exposed porous anophthalmic implants in eviscerated patients

“…2,4,6,[8][9][10][11][12][13][14] Exposure rates have been shown to increase after motility peg insertion in some studies. 2,7,8,12,15 Surgical techniques for exposure repair are primary revision 11 and secondary patch grafting using various materials with and without implant removal and exchange. Endogeneous and exogeneous materials have been used for grafting.…”

“…Implant infection may occur late with or even without pegging. 15 Generally, antibiotics used intraoperatively and postoperatively have been proven to avoid infection. As an additional caution to prevent a possible infection, we impregnated the implant in a mixture of gentamicin and cefuroxime just before implantation.…”
