RESUMEN
Objective To evaluate the clinical efficacy of the application of auricular composite tissue flap in treatment of nasal alar de-fect. Methods 43 cases of nasal defects patients were admitted to our hospital from January 2008 to March 2013, 23 cases of them were treated with auricular composite tissue flap transplantation, and the other 20 cases were given nasolabial sulcus flap transfer operation. All patients were followed-up for 6 to 12 months, and the rate of secondary surgery, proliferation of scar, and flap survival of the two groups were compared. Results Treatment of auricular composite tissue flap transplantation has more advantages in terms of the rate of secondary surgery, proliferation of scar, and flap survival, and the difference is of statistical significance (P<0. 05). And there is no obvious differ-ence in satisfaction degree of cosmetic outcomes. Conclusion Auricular composite tissue flap surgery has the advantages of simple opera-tion, good appearance and good efficacy.
