[Research progress of autogenous cartilage scaffold carving method in rhinoplasty].

[OBJECTIVE] To summarize the research progress of autogenous cartilage scaffold carving method in rhinoplasty.

[METHODS] The relevant literature about the autogenous cartilage scaffold carving methods in rhinoplasty in resent years at home and abroad was reviewed, and the carving skills, shape, and application scope of different parts of nasal scaffolds were summarized and analyzed.

[RESULTS] Willow-leaf shape is still the main method of cartilage scaffold in the back of the nose. However, in nasal reconstruction, it can be carved into an L-shaped scaffold with the nasal columella scaffold through mortise and tenon structure. And it can also crush the autologous cartilage and wrap it with the autologous fascia tissue to form a new nasal dorsal scaffold. The nasal tip scaffold is improved by changing the shape of traditional nasal tip cartilage cap and wrapping with fascia tissue; the nasal alar scaffold has M-shape, q-shape, carving methods; the nasal columella and nasal septum are mostly used "2+2" combined fixed scaffold. The cartilage scaffolds of lateral nose and nasal base are mainly carved in the shape of "" and crescent.

[CONCLUSION] As a rhinoplasty scaffold, there are various carving methods for autogenous cartilage. With the innovation of surgical technique and the improvement of sculpting technique, the effect of autologous cartilage graft in rhinoplasty is getting better and better; meanwhile, tissue engineered cartilage is being applied in rhinoplasty.
