Gore-Tex Chin Implants

Design: A 17-year retrospective medical chart review at a teaching hospital, community hospital, and private facial cosmetic surgery center. A total of 521 patients (122 male and 399 female; age range, 13-70 years) were followed for 12 months to 17 years. All patients had undergone GORE-TEX implantation rhinoplasty (685 implants in 158 primary procedures and 508 secondary procedures) performed by 1 surgeon. Patient satisfaction, expressed with respect to desired cosmetic benefit and functional outcome, and physician assessment, based on aesthetic improvement, technical considerations, and complications, were evaluated. Results were assessed according to the follow-up notes in the medical chart reflecting patients' and surgeon's comments and full preoperative and postoperative photographic documentation. Results: GORE-TEX alloplasts, 1 to 10 mm thick, implanted in the nasal dorsum (n = 264), lateral nasal wall (n=252), supratip dorsum (n=85), and premaxilla (n=84) showed excellent stability and tissue tolerance. Biological complications that required implant removal occurred in 1.9% of patients and included infection, soft tissue swelling, migration, and extrusion. Conclusions: With the exception of the nasal tip, columella, or problems in which corrections would require rigidity of the grafted or implanted material, the GORE-TEX alloplast is a safe, inexpensive, and predictable alternative to autografts. In the present series, more than 95% of implants used were 1 to 4 mm thick. In the remaining 5%, 6 implants ranged from 8 to 10 mm thick, and we found them acceptable. It is our opinion that for both primary and secondary rhinoplasty with adequate endonasal and external soft tissue coverage, GORE-TEX should be strongly considered for major and minor corrections of the nasal wall and bridge in properly selected patients.

flap has a higher donor-site morbidity than other flaps, its anatomic structure is regular, and turning of the patient position is not required in an operation, shortening the operative time. In addition, the flap does not require secondary defatting and may adapt easily to the surrounding tissue because it is quite thin. It has been sufficient to provide the reconstruction of the full-thickness loss of the cheek with good aesthetic and functional results. The microsurgical anastomosis was performed on ipsilateral neck vessels. We suggest that the free radial forearm flap is a suitable and useful technique for treating the full-thickness cheek defects involving the mandible and lip.

We present an easy alternative to enhance rhinoplasty in patients with wide nasofrontal angles. By implanting PTFE (GORE-TEX) in the glabella region, we obtained a significant change in nasal shape. Twenty-seven patients were treated with this technique with no complications and with good results. The material showed excellent biocompatibility, matching the host tissues perfectly.

One of the primary advancements in cosmetic facial surgery has been the realization of volume loss in aging and volume replacement via cosmetic surgery [3-6]. The abundance of midfacial volume is one of the main reasons that makes a person look young, which means having the right amount of fat in the right areas of the face. The loss or shift of this fat is a main contributor to facial aging [7]. Loss of volume and volume shift occur in all regions of the face and neck and are the reasons for aged appearance [5, 6].The youthful midface has voluminous and

Objective/Hypothesis: The aim of this study was to assess the tissue response to Gore-Tex (expanded polytetrafluoroethylene) in rats and compare the results of surgical placement modalities. Study Design: Prospective animal study. Materials and Methods: Experiments were performed in 18 young Sprague-Dawley rats that were divided into 3 groups. Gore-Tex patches were implanted subcutaneously over the periosteum in the first group and under the periosteum in the other groups. Gore-Tex was immersed in an antibiotic-containing solution in the third group. All animals were killed 4 weeks after the procedure. The tissue samples were stained with hematoxylin and eosin stain and evaluated using a light microscope. Results: The Gore-Tex patches were displaced and not observed at the originally implanted sites in the first group. The Gore-Tex patches were observed at the originally implanted sites in the other groups. In group 1, edema and inflammation were prominent. In the second group, ossification was detected in 5 rats and foreign-body reaction and edema were identified in 1 rat. In the third group, all of the rats were found to have developed ossification, but no inflammatory reactions were observed. Conclusions: The results suggest that implanting synthetic graft materials immersed in an antibiotic solution at the subperiosteal plane provides better stabilization and low complication rates.

Background: A hyaluronic acid (HA) filler intended for non-surgical improvement of chin appearance should ideally be of high strength/ firmness (high G') to allow for deep injections on the bone. HA SHA (Restylane ® Shaype ™) is a new hyaluronic acid (HA) injectable with high G' and high HA concentration (25 mg/mL), engineered by the new NASHA-HD ™ (High Definition) technology. HASHA is suitable to be placed periosteally, aiming to mimic the natural shape of the bony chin. This pivotal clinical investigation evaluated effectiveness and safety of HA SHA for augmentation and correction of chin retrusion. Methods: Subjects ≥18 years with mild or moderate chin retrusion by the Galderma Chin Retrusion Scale (GCRS), were randomized 3:1 to HA SHA (n=103) or no treatment (n=37). Assessments included GCRS (blinded evaluator), aesthetic improvement (Global Aesthetic Improvement Scale [GAIS]), subject satisfaction, and safety. Results: GCRS responder rate (≥ 1-grade improvement from baseline) was significantly higher for HA SHA (83.3%) vs controls (10.8%) at month 3 (P<0.001), and maintained through month 12 (P<0.001). Aesthetic improvement was high throughout the study in the HA SHA group, according to investigators (≥97%) and subjects (≥89%). Overall, subject satisfaction was high at month 3 and maintained at month 12. Product-or injection-related adverse events were mostly mild or moderate and transient. No product-or injection-related serious adverse events were reported. Conclusions: HA SHA , a new NASHA-HD ™ injectable with extra strength/firmness, was safe and effective for chin augmentation and correction of chin retrusion, with high aesthetic improvement and subject satisfaction throughout 12 months.

BACKGROUND. Injectabtc synthetic materials have been used for augmentation of soft tissue defects, correction of ivrinkles, and augmentation of facial features such as the nasal dorsum. Success has been limited by inflammatory reactions, material migration, and the difficulty of removal should complications oceiir. OBJECTIVE. To evahtate complications resulting from soft tissue augmentation with injectable alloplastic materials. METHODS. Retrospective review of seven cases. Clinical history, treatment, histopathotogic findings, and outcomes are assessed. RESULTS. Inflammatory reaction and tissue damage zvere refrac-tory to antibiotics and steroids, and surgery was required to remove the foreign material Histologic examination revealed giant cell foreign body reaction in ail cases. CONCLUSION. Injectable synthetic polymers can produce significant complications including deformity and inflammatory tissue destruction, the control of which is complicated by the difficulty of removing the materials. Removable tissue fillers, such as e-PTFE, or natural materials such as collagen, autologous, fat, or Alloderm, should be considered instead.
