Dual Plane Augmentation Genioplasty Using Gore-Tex Chin Implants

Abstract

BackgroundThe chin shape and position is important in determining the general shape of the face, and augmentation genioplasty is performed alone or in combination with other aesthetic procedures. However, augmentation genioplasty using osteotomy is an invasive and complex procedure with the potential to damage mentalis muscle and mental nerve, to affect chin growth, and prolonged recovery. Our aim was to present our experience with a modified augmentation genioplasty procedure for hypoplastic chins using a Gore-Tex implant.MethodsTwo vertical slit incisions were made at the canine level to create a supraperiosteal pocket between the incisions, preserving the periosteum and mentalis muscle. Minimal sub-periosteal dissection was performed lateral to the incisions along the mandibular border. The both wings of implant were inserted under the periosteum to achieve a stable dual plane implantation.ResultsIn total, 47 patients underwent dual plane chin augmentation using a Gore-Tex implant between January 2008 and May 2013. The mean age at operation was 25.77 years (range, 15-55 years). There were 3 cases of infection; one patient was treated with antibiotics, the others underwent implant removal. Additionally, two patients complained of postoperative parasthesia that spontaneously improved without any additional treatment. Most patients were satisfied with the postoperative outcomes, and no chin growth problems were observed among the younger patients.ConclusionDual plane Gore-Tex chin augmentation is a minimally-invasive operation that is simple and safe. All implants yielded satisfactory results with no significant complications such as mental nerve injury, lower lip incompetence, or chin growth limitation.

Effect of pore size and spacing on neovascularization of a biodegradble shape memory polymer perivascular wrap

“…Designs –a–d possessed two statistically unique pore spacings (a,b = 151 ± 50 μm and c,d = 229 ± 51 μm) and pore sizes (a,c = 635 ± 51 μm and b,d = 1,160 ± 64 μm) to enable independent evaluation of pore spacing and size effects on material properties and in vivo responses (statistical analysis of pore size and spacing described in Appendix, Table S7). Other designs served as nonporous or microporous controls: non laser‐ablated PCL‐based SMPs (Design e) and a ~6 × 8 × 0.64 mm 3 piece of commercially available Standard Wall GORETEX tubing comprised of ePTFE with 10–30 μm‐sized micropores (Design f) (Table 2, Figure 2) (Kim, Lim, Park, & Lee, 2014).…”

The use of collagen-coated polypropylene meshes for nasal reconstructive surgery

“…Mersilene (polyethylene terephthalate) is used for volume correction in nasal reconstruction; though it cannot be used for structural support [44]. Gore-tex is most frequently used for chin augmentation [45], for dorsum nasi or lateral walls augmentation, premaxillary graft, lobule or supralobule [42]. Polypropylene is an affordable synthetic material, easy to implant, with a wide availability and flexibility, being found in different and numerous forms.…”
