The Frontalis Suspension Technique is indicated in cases with minimal or no levator function. At the beginning sutures were used as sling material and after further modifications suture material was replaced by autologous or homologous fascia lata. In the last years ePTFE has proved to be a very suitable sling material.
Since ePTFE is very biocompatible, it was used for this modified frontalis suspension technique. The anterior tarsal surface is exposed and a small tunnel is created between the skin incision and the second incision superior to the brow. An 0.3 mm thin ePTFE strip is induced into the tunnel and connects the upper lid with the frontalis muscle. The ePTFE Soft Tissue Patch must be exactly adapted to the tarsus and has to be deeply sutured to the frontalis muscle below the brow incision. Since 1994 17 modified frontalis suspension procedures have been performed on 14 patients.
The functional and cosmetic result were good in nearly all patients. No implant had to be removed during the follow up period.
The new technique of frontalis suspension using a ePTFE strip guarantees a regular upper lid lifting by the axial and direct connection of the anterior tarsal surface with the frontalis muscle.
额肌悬吊术适用于提上睑肌功能极小或无功能的病例。起初，缝线被用作悬吊材料，经过进一步改进后，缝线材料被自体或同种异体阔筋膜所取代。近年来，ePTFE已被证明是一种非常合适的悬吊材料。
由于ePTFE具有良好的生物相容性，因此被用于这种改良的额肌悬吊术。暴露睑板前表面，并在皮肤切口与眉上方的第二个切口之间创建一个小隧道。将一条0.3毫米细的ePTFE带引入隧道，连接上睑与额肌。ePTFE软组织补片必须与睑板精确贴合，并在眉切口下方与额肌进行深层缝合。自1994年以来，已对14例患者进行了17次改良额肌悬吊手术。
几乎所有患者的功能和美容效果都很好。随访期间无需取出植入物。
使用ePTFE带进行额肌悬吊的新技术通过睑板前表面与额肌的轴向和直接连接，保证了上睑的正常提升。
