Outlook of magnesium alloy for rhinoplasty material

Abstract

Rhinoplasty is one of the famous cosmetic surgeries all over the world, as it not only benefits congenital nasal bone dysplasia patients, but also satisfy a part of people who want to look more beautiful and perfect. The materials commonly used in current rhinoplasty are prone to failure of rhinoplasty because of autologous absorption, loosening and slipping of nasal scaffold due to poor tissue compatibility, and difficulties in secondary repair^[1-2]. Biodegradable magnesium alloy material is one of the most ideal biomedical materials with great application value. Mechanically, the biodegradable magnesium alloy material has good mechanical properties, similar to the mechanical properties of human bone; the density is similar to that of human bone. Biologically, degradable magnesium alloy material has the characteristics of excellent biocompatibility, biological activity, degradation products can be easily absorbed or excreted by human tissues; degradable magnesium alloy can induce cell differentiation growth and blood vessel growth^[3]. This article analyzes the possibility of using degradable magnesium alloy material as a scaffold material for rhinoplasty and suggests that this porous nasal scaffold can be prepared by 3D printing method. By using this method, a restorative nasal plastic effect can be obtained by guiding the regrowth of autologous nasal bone tissue. From a long-term perspective, the surgical results achieved by using magnesium alloy as a scaffold material for rhinoplasty are what the medical aesthetic community has been seeking. The use of biodegradable magnesium alloy as a rhinoplasty material is a new approach that is feasible and has potential for future economic and social benefits, but this approach needs further research and experiments to be validated in the future.
