Experience With Autologous Nasal Septum Cartilage Combined With Conchal Cartilage in Nasal Tip Reconstruction.

ABSTRACT

OBJECTIVE: There has been an increase in use of autologous costal cartilage for nasal tip shaping material. However, there are deficiencies in using this plastic material, such as a hard nasal tip, poor nasal tip elasticity and mobility postoperatively, and some nasal tip skin thinning that allows the shape of the cartilage grafts to be felt on the surface of the nasal tip skin. To address these problems, we have combined autologous nasal septum cartilage and conchal cartilage as nasal tip graft materials, which achieve a natural shape and realistic touch postoperatively. METHODS: From January 2017 to September 2019, a total of 47 patients with nasal septal cartilage combined with conchal cartilage transplantation for nasal tip plasty were screened for a retrospective study. They were followed up and evaluated for 6 to 25 months postoperatively. The operation was performed through an incision in the nose. During the operation, a piece of septal cartilage was cut to make a columella strut. Using one side of the cavitas conchae and cymba conchae cartilage as the graft material, 2 long strips of cartilage were excised for the septum extension graft, and a piece of cap cartilage was transplanted to the top of the nasal tip cartilage scaffold. RESULTS: The time between the operation and follow-up was greater than 6 months, with the range of follow-up and evaluation being from 6 to 25 months. Forty-six patients were satisfied with the shape of the nose. One patient complained that the nasal tip was round and large after 1 month postoperatively, but after 6 months, he was satisfied with the shape of the nasal tip after daily use of a nasal clip. In one male case, the implant was removed more than 7 months postoperatively because of hematoma and infection secondary to nasal trauma. There were 2 cases of nasal tip numbness, both of which recovered spontaneously after 12 months. After the operation, the shape of the nasal tip was round, no cartilage contour was seen on the surface, no collapse of upper nasal tip, no obvious deviation of the nasal dorsum and columella, and no deformation and displacement of the nasal tip cartilage scaffold. At the 6-month follow-up visit, each patient palpated the nasal tip for evaluation. Most patients felt their nose felt realistic and that they had good nasal tip motion. Only 1 patient felt that the nasal tip and the nasal dorsum were moving together when the tip of the nose was being pushed. CONCLUSIONS: Nasal septum cartilage and conchal cartilage can be combined as a graft material for reconstruction of the nasal tip. This technique uses different characteristics of each of the 2 cartilages to achieve a more realistic and esthetic outcome.
