Abstract
BACKGROUND: Strong strut structures are necessary for nasal tip projection in Asian rhinoplasty. Traditionally, strut structures have been constructed by open skin incisions. METHODS: Barbed threads were implanted for rhinoplasties. The threads have multiple sharp barbs and umbrella-like longitudinal splits at both ends. Autologous micronized fat tissue graft was also simultaneously used when volume replacement was necessary. RESULTS: Since 2003, barbed threads have been used in approximately 1,200 rhinoplasties for nasal tip projection, dorsal length elongation, and nostril correction. The results of relative length ratios comparing true lateral photographs showed significant increase in tip projection. CONCLUSION: The results of long-term observation (> 6 months) indicate that the surgical procedure of lifting the nasal tips with barbed threads is significantly effective for the anterior projection of nasal tip in Asians.
