Surgical materials for lengthening nasal columella;

The commonly used material for nasal columella lengthening is solid polymer material. At present, silicone rubber is the mainstream. Silicone rubber can be prefabricated into nasal prostheses of various shapes and models, such as nose tip, alar and columella. There are two kinds in common use: willow shape and L shape. Silicone rubber has good elasticity, easy molding, good chemical inertia, non-toxic, non-carcinogenic, non-teratogenic and good histocompatibility. After implantation, there was a slight transient inflammatory reaction in the local area, and a thin fibrous capsule was formed around it in the later stage. It is a widely used and effective material in rhinoplasty at present.

Another surgical material used to lengthen the nasal columella is polytetrafluoroethylene (also known as swelling). The material has high and low temperature resistance, good chemical stability, corrosion resistance and histocompatibility, and is non-toxic, carcinogenic and teratogenic.
