Reshaping the nasal tip with autologous nasal septum cartilage combined with ePTFE grafts and autologous auricular cartilage grafts

Abstract

To evaluate the clinical effects of reshaping the nasal tip with autologous nasal septum cartilage combined with expanded polytetrafluoroethylene (ePTFE) and autologous auricular cartilage grafts. The nasal septal cartilage combined with ePTFE (group A, 70 cases) and autologous auricular cartilage grafts (group B, 48 cases) were used separately. The therapeutic effect and operation time were compared using the t-test or the χ²-test by the SPSS 12.0 software. The mean operation time (x(-) ± s) in group A was less than those in group B and the difference was significant (t = 13.258, P = 0.000). The width of nasal tip equal to (6 - 8) mm was found in 67 cases (95.7%) in group A, and 46 cases (95.8%) in group B. There was no statistically significant difference between group A and group B (χ² = 0.001, P = 0.996). The correction result of the nasal tip projection, angle of ration, the included angle of nasal dorsum and nasal columella and the height of the nasal tip did not show statistically significant difference between group A and group B (χ² value were 0.001, 0.069, 0.149, 0.073, respectively, all P > 0.05). The autologous nasal septal cartilage combined with ePTFE and autologous auricular cartilage grafts showed similar clinical effect.
