“…24 Many organic and inorganic materials have been proposed for use in frontalis suspension, including skin and muscle, 25 autologous and homologous fascia lata, 26 temporal fascia, 27 umbilical vein from a conserved placenta, 28 and long palmar tendon, 29 as well as Supramid, 30 Gore-Tex, 11 Mersilene, 31 Prolene, 32 expanded polytetrafluoroethylene, 33 and silastic bands. 34 In regards to inorganic materials, there is always the concern that these can lead to the formation of foreign-body granulomas, infection, or extrusion. 26 According to literature, 35 non-autogenous materials 1 10 12 0 1 1 2 28 22 9 12 10 13 2 1 2 1 3 0 1 0 2 2 9 2 3 1 0 1 3 1 0 1 3 3 14 12,5 0 2 1 2 32 25 12 16 13 16 4 1 4 1 4 À1 2 0 2 31 25 11 14 12 15 5 1 4 1 3 1 3 1 2 3 are known to have higher ptosis recurrence rate (20-35%, depending on the material used and the follow-up period) and, moreover, a higher exposure keratopathy, infection and granuloma formation rates.…”
