title: [Frontalis suspension with "expanded polytetrafluoroethylene (ePTFE) strips" in congenital ptosis].
abstract: BACKGROUND
  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.
  
  
  METHODS
  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.
  
  
  RESULTS
  The functional and cosmetic result were good in nearly all patients. No implant had to be removed during the follow up period.
  
  
  CONCLUSIONS
  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.
