title: Aesthetic and restorative midface lifting with hand-carved, expanded polytetrafluoroethylene orbital rim implants.
abstract: The midface lift represents an important advance in aesthetic and reconstructive surgery. However, the need for reliable fixation along the orbital rim has been a significant challenge. Furthermore, volume is needed at the orbital rim, to compensate for long-term remodeling of the bone of the orbital rim and malar face. A technique using a hand-carved, expanded polytetrafluoroethylene implant that is permanently anchored to the orbital rim with titanium microscrews, creating a site for fixation of the advanced midface soft tissues, was developed. This report presents a retrospective, uncontrolled, case series of 41 consecutive patients who underwent transconjunctival midface operations with these implants, and it addresses a variety of midface aesthetic and reconstructive deficits. Only patients with at least 6 months of follow-up data were included in the study. To date, significant complications have been limited. The complications included two cases of implant palpability, with only one requiring surgical modification. One patient underwent implant removal because of skin breakdown and infection related to recurrent squamous cell carcinoma. One patient required revisional lateral canthoplasty for reasons of symmetry. On the basis of this series, hand-carved, expanded polytetrafluoroethylene implants seem to have significant advantages, compared with previously available orbital rim implants. These advantages include the ability to easily modify the implant for the individual anatomical needs, the creation of a secure anchor for fixation of advanced midface soft tissues, excellent tolerance of the implant material, and the ability to place the implant with limited exposure. The greatest disadvantage is the need for the surgeon to carve the implant, which requires time and carving skill. Despite this limitation, the technique is promising.
