[Resection and one-stage repair of basal cell carcinoma of external nose]

To present the method of resection and one-stage repair of basal cell carcinoma of external nose.

Sixty-two patients with basal cell carcinoma of external nose were hospitalized and underwent surgeries from January 2002 to June 2010. The defects after resection were as follows: 1 partial defect of soft tissue of lateral ala nasi, associated defect of ala nasi margin, total defect of ala nasi, defect of soft tissue of apex nasi, defect of apex nasi and ala nasi, defect of the bridge of the nose. Various flaps were applied according to the degree of defects. With nasal parabolic sulci and nasolabial sulcus as the center, different flaps were used, including advanced skin flap, pedicle tunnel island flap of nasolabial sulcus, and flip flap of nasolabial sulcus, forehead axial flap, dissociated auricle compound soft tissue flap for one-stage repair respectively.

Two flaps failed because of thanatosis after the surgeries. One flap mostly was a necrosis with the upper small part survived. A marginal partial necrosis of the flap appeared in 2 patients. Two fixing nasal apex and nasal wing suffered a partial circum exfoliation. All other 55 flaps were successfully implanted with satisfying looks and breathing functions with the exception of 1 complaining about obvious nasal obstruction. The rest were followed up for 6 months to 8 years with no relapse.

Most of the tumors of external nose are basaloma, and the margin of safety should be secured during the operation with Mohn's surgery, and once thoroughly resected, there are barely relapses, and radiotherapy or chemotherapy is unnecessary. Pedicled skin flaps can be used as in one-stage repairing of the defect of external nose, with high rate of success and close color shade and good outcome.
