Fifty-five frontalis sling procedures were performed with use of 4--0 polyfilament, cable-type ophthalmic suture (Supramid Extra) as the material for suspension. Recurrences numbered 16, recorded through a follow-up period of one to ten years. Trauma accounted for five recurrences. A pattern of gradual droop of the lid operated on became most obvious between six and ten years postoperatively and accounted for six of seven recurrences during this period. These findings suggest that this suture material is a poor alternative to fascia lata for permanent frontalis suspension in patients with congenital ptosis and should be used only in unusual circumstances, or when a temporary procedure is indicated.
采用4-0多丝缆索型眼科缝线（Supramid Extra）作为悬吊材料进行了55例额肌悬吊手术。通过1至10年的随访，记录到16例复发。外伤导致5例复发。手术眼睑逐渐下垂的模式在术后6至10年最为明显，在此期间7例复发中有6例为此原因。这些发现表明，对于先天性上睑下垂患者，这种缝线材料作为永久性额肌悬吊术的材料远不如阔筋膜，仅应在特殊情况下或有临时手术指征时使用。
