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