Objective To explore a new method of nasal tip plasty and its clinical effect, which is much accorded with biomechanical properties of the human body. Methods From June 2010 to March 2016, a total of 33 cases of nasal tip surgery, 6 males and 27 females, were performed. Ages ranged from 22 to 46 years in this group. Ear cartilage was trimmed into two strips and sutured them together in a M shape. When located to the original position of the nasal alar cartilage, the M shaped cartilage could be used in nasal tip; when fixing part of it on the nasal septum or lengthened nasal septal cartilage, the M shaped cartilage could be used in cosmetic surgery of nasal tip lengthening. Results The follow-up period was from one month to 60 months, with average 14 months. 29 patients (87.9%) were satisfied with the efficacy and 2 patients were suffered from infection (6.1%). Conclusions When the M-shaped cartilage is fixed with lengthened nasal septum, it can lengthen the nasal tip much more and the contouring and texture of nasal tip are better than that of using a shield or a cap cartilage graft.
