“…Polypropylene mesh was also used on reconstruction of auricular defect as alloplast. [7][8][9][10][11][12] This is in accordance with the result of this case report. At follow up review 11 months postoperatively, polypropylene mesh material that was used in this case did not cause any complaints from the patient nor sign of material rejection.…”

“…Polypropylene mesh was also used on reconstruction of auricular defect as alloplast. [7][8][9][10][11][12] The following case is Ossifying Fibroma which has extended to buccal part of maxilla and a half part of zygoma, so that the tumor resection had resulted in a facial deformity. To compensate for the deformity, the authors performed a reconstruction where the inside of the maxillary buccal wall part was supported with 3 layers of foldable polypropylene mesh material.…”

“…Silicone appeared in the 1950s and was the first alloplastic material to gain wide use. It is nonporous, inert and doe not change its shape with time 1,2,9. However after implantation, silicone has shown to form a thick capsule of fibrous tissue leading to poor attachment to the body and high change of movement leading to extrusion of the implant 1,2,9.…”

Currently, autologous cartilage provides the gold standard for auricular reconstruction. However, synthetic biomaterials offer a number of advantages for ear reconstruction including decreased donor site morbidity and earlier surgery. Critical to implant success is the material’s mechanical properties as this affects biocompatibility and extrusion. The aim of this study was to determine the biomechanical properties of human auricular cartilage. Auricular cartilage from fifteen cadavers was indented with displacement of 1 mm/s and load of 300 g to obtain a Young’s modulus in compression. Histological analysis of the auricle was conducted according to glycoprotein, collagen, and elastin content. The compression modulus was calculated for each part of the auricle with the tragus at 1.67 ± 0.61 MPa, antitragus 1.79 ± 0.56 MPa, concha 2.08 ± 0.70 MPa, antihelix 1.71 ± 0.63 MPa, and helix 1.41 ± 0.67 MPa. The concha showed to have a significantly greater Young’s Elastic Modulus than the helix in compression (p < 0.05). The histological analysis demonstrated that the auricle has a homogenous structure in terms of chondrocyte morphology, extracellular matrix and elastin content. This study provides new information on the compressive mechanical properties and histological analysis of the human auricular cartilage, allowing surgeons to have a better understanding of suitable replacements. This study has provided a reference, by which cartilage replacements should be developed for auricular reconstruction.Electronic supplementary materialThe online version of this article (doi:10.1007/s10439-016-1688-1) contains supplementary material, which is available to authorized users.

“…Unfortunately, the combined complications of these autologous materials (such as donor site morbidity, limited amount of donor tissue, burdensome carving dilemmas, and uncertain graft resorption and remodeling) frequently counter their advantages [6]. When insufficient septal or auricular cartilage is available for grafting, the reconstructive surgeon is often forced to choose an alternative donor site, or another material [1]. Sheen [7] noted the importance of considering augmentation of the radix to obtain an adequate balance when doing certain rhinoplasties, i.e., when the patient presents a depressed radix, and since then Guerrerosantos have decided to use his own technique.…”

Autogenous fascia, including the temporalis fascia, has a particular role in rhinoplasty as radix and dorsal onlay grafts. The main purpose of this study is to achieve desired appearance of facial harmony using either a complete or partial sheet of deep temporal fascia as a radix graft in the patients with required permanent radix augmentation. This is a prospective study of 15 patients who referred to Gandi Day Clinic, Tehran, Iran, between 2005 and 2006 and underwent rhinoplasty including nasal radix augmentation using deep temporalis fascia through external rhinoplasty approach. The patients with hump noses had low radix and required radix augmentation. Full sheet facial graft was used in 13 patients. Partial sheet facial graft was used in two patients. As a donor site problem, minor hematoma was observed in one patient. Temporary hair loss in incision line was another problem which were seen in five. As for the recipient site, no infection, persistent erythema of nasal skin extrusion, visibility, displacement of graft materials or irregularity of graft contour were observed postoperatively. Resorption rate was approximately 30% for grafted fascia. Using fascia grafts in radix point, the revision rate was minimal. In order to augment the radix, if 4 mm augmentation is needed, it should be considered that full sheet fascia graft alone would be insufficient. If more than 4 mm of augmentation is needed, 30% overcorrection would manage well the permanent radix augmentation without any problem.
