[ use of Mersilen mesh for wrapping of hydroxyapatite [HA] orbital implant: a new procedure with low complications]

ABSTRACT

To report the results of a wrapping technique for hydroxyapatite orbital implants by using mersilen mesh. 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 of a secondary procedure. We recorded results and potential problem before and after pegging due to mersilen mesh. 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 [5 months 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 inflammation after pegging. One case had exposure, 4 cases had granulation tissue, and 3 patients had discharge. 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
