Hybrid columellar strut using nasal crest bone of the maxilla and conchal cartilage for nasal tip stability in rhinoplasty for East Asian patients

Background Proper nasal tip projection and rotation are essential for an aesthetically pleasing nose. However, East Asians usually have thicker skin underdeveloped cartilage compared to Caucasians. Thus, techniques such as the septal extension graft, columellar strut L-shaped alloplastic implants been introduced additional support projection. no consensus exists regarding optimal method.Methods A hybrid made of osteochondral graft recombined with crest maxilla conchal was devised. In a cadaveric study, changes due external bending force costal in same dimension were measured. comparative we divided 20 subjects into two groups according material used graft: (experimental group) double-layered (control group). Preoperative, 1-month postoperative, 1-year postoperative anthropometric measurements between groups.Results showed superior mechanical strength. average change labial angle significantly smaller experimental group (–0.7°±1.16° vs. 2.2°±1.32°, P=0.015). The stability.Conclusions We devised new confirmed its firmness stability. Considering suggested indications contraindications, can be modality plasty Asian rhinoplasty that provide sufficient long-term
