the use of mersilen mesh for wrapping of hydroxyapatite (ha) orbital implant: a new procedure with low complications

purpose: to report the results of a wrapping technique for hydroxyapatite orbital implants by using mersilen mesh. methods: this study is prospective interventional case series conducted on records of 55 consecutive patients who received a mersilen mesh-wrapped ha orbital implant after enucleation or as a secondary procedure. we recorded results and potiential problem before and after pegging due to mersilen mesh. results: twenty nine males (52.7%) and 26 females (47.3%) underwent the procedure. mean age was 27.6±13.7 (33 months to 71 years). average follow up was 19.1±8.1 (1 month to 68 months). there were 28 (51%) primary enucleations and 27 (49%) secondary orbital implants. thirty eight patients (65.5%) underwent peg placement. average duration to pegging was 6.5±11.27 months (5months to 39 months). before pegging, 2 patients (5.2%) had implant exposure; one after a primary implant and another following a secondary implant. one exposure resolved spontaneously and one case required a mucous membrane graft. none of the patients had socket imflammation after pegging. one case had exposure, 4 cases had granulation tissue, and 3 patients had discharge. conclusion: mersilen mesh is an alternative option to sclera as a wrapping material for porous orbital implants. it is simple to use, readily available, and low-cost
