[Morel-Fatio temporary management of the paretic eyelid]

Various alloplastic materials have been used to reestablish proper function of paretic upper eyelids. Modifying Morel-Fatio's method, the spring had been bent in a W-fashion and located in such a position that three dimensional movement of the lower branch was possible. Complications of the original method like swelling and perforation could be explained by occasional allergies against chromium and nickel. Therefore we used a new titan-molybdaen alloy, which has a slightly higher elasticity modul than the chrom-nickel alloy. The new material's characteristics correlate well with our own in vivo measurements of the strength of the levator palpebrae superioris muscle. Clinical observations during the last 3.5 years show an improvement by the use of the titan-molybdaen alloy for the durability of elasticity as well as for tissue compatibility.
