“…None of the complications arose from donor site injury, and the morbidities were limited to graft warping and infection. Among another cohort of Asian rhinoplasty patients, a 10.7% complication rate was observed with silicone-PTFE composite implants 11. No cases of extrusion were noted in that sample, and issues were limited to malposition (5.4%), erythema (2.3%), and infection (1.1%).…”

“…Among another cohort of Asian rhinoplasty patients, a 10.7% complication rate was observed with silicone-PTFE composite implants. 11 No cases of extrusion were noted in that sample, and issues were limited to malposition (5.4%), erythema (2.3%), and infection (1.1%). Overall, the literature demonstrates that complication rates of synthetic implants (approximately between 1% and 10%) are comparable to that of autogenous cartilage with the additional uncommon risk of extrusion.…”

Kamel et al 8 reported the use of a posterior rotation flap technique during the distraction osteogenesis of ULS. The increase in intracranial volume was considered sufficient in this report. In addition, they showed that the posterior ration flap technique provides a sufficient increase in intracranial volume, and our method is comparable with their study. The bone flap in our method was slightly smaller than that in their study, and the location of the valve was localized near the occipital region. 8 Barrel stave osteotomy (case 2 only) and back cutting were added to increase intracranial volume, and an absorbable plate was used to reinforce the hinge area.In case 1, because the device was buried in the skin, the distraction was slightly inadequate. However, if the length of the device was made too long, it would become inconvenient for daily life. Consequently, it was determined that the length of the device should only be selected after the amount of distraction has been fully considered.The rotation advancement distraction osteogenesis technique is a simple method of treatment for posterior plagiocephaly, which is caused by unilambdoid craniosynostosis. However, this technique has limitations since we only tested it in 2 cases. Subsequently, a larger sample size and a longer follow-up are required to compare with other techniques.Furthermore, this technique did not provide any solution for the displacement of ears, or cranial base and facial deformity, and would require surgery to remove the device.

“…It is to implant the prosthesis into the nose through surgery to achieve the effect of raising the back of the nose and shaping the overall shape of the nose. Silicone prosthesis is an ideal material for rhinoplasty, which has good compatibility, little irritation to nasal tissues, low price, and easy carving [ 38 , 70 ]. After the rhinoplasty operation, the recipient should try to minimize adverse stimuli such as touch and impact at the surgical site to ensure the normal transformation of the capsular fibers [ 70 ].…”

Review of Plastic Surgery Biomaterials and Current Progress in Their 3D Manufacturing Technology

Plastic surgery is a broad field, including maxillofacial surgery, skin flaps and grafts, liposuction and body contouring, breast surgery, and facial cosmetic procedures. Due to the requirements of plastic surgery for the biological safety of materials, biomaterials are widely used because of its superior biocompatibility and biodegradability. Currently, there are many kinds of biomaterials clinically used in plastic surgery and their applications are diverse. Moreover, with the rise of three-dimensional printing technology in recent years, the macroscopically more precise and personalized bio-scaffolding materials with microporous structure have made good progress, which is thought to bring new development to biomaterials. Therefore, in this paper, we reviewed the plastic surgery biomaterials and current progress in their 3D manufacturing technology.

Background In this study, we evaluate the value of novel suture material based on monofilamentous-extruded polyfluoroethylene (PTFE) compared to polypropylene (PPL) and Fiberwire (FW). Materials and methods 60 flexor tendons were harvested from fresh cadaveric upper extremities. 4–0 sutures strands were used in the PPL, FW and PTFE group. Knotting properties and mechanical characteristics of the suture materials were evaluated. A 4-strand locked cruciate (Adelaide) or a 6-strand (M-Tang) suture technique was applied as core sutures for a tendon repair. Two-way ANOVA tests were performed with the Bonferroni correction. Results Stable knotting was achieved with 5 throws with the PPL material, 7 throws for FW and 9 throws for PTFE. In the PPL group, linear tensile strength was 45.92 ± 12.53 N, in the FW group 80.11 ± 18.34 N and in the PTFE group 76.16 ± 29.10 N. FW and PTFE are significantly stronger than PPL but show no significant difference among each other. Similar results were obtained in the subgroup comparisons for different repair techniques. The Adelaide and the M-Tang knotting technique showed no significant difference. Conclusion Fiberwire showed superior handling and knotting properties in comparison to PTFE. However, PTFE allows easier approximation of the stumps. In both, M-Tang and Adelaide repairs, PTFE was equal to FW in terms of repair strength. Both PTFE and FW provide for a robust tendon repair so that early active motion regimens for rehabilitation can be applied.

Silicone-Polytetrafluoroethylene Composite Implants for Asian Rhinoplasty

Abstract: I-shaped silicone-PTFE composite implants are feasible for both primary and secondary augmentation rhinoplasty in Asians. Early outcomes data suggest an overall complication rate that is comparable to PTFE alone.
