Abstract: 【Abstract】 Objective To evaluate the effect of local flaps on repair of defects after surgical removal of nasal skin tumors. Methods A total of 65 patients with nasal skin tumors were enrolled from Department of Dermatology, People′s Hospital of Xinjiang Uygur Autonomous Region between March 2015 and August 2016, and subjected to surgical removal of the nasal skin tumors. According to the location, size, shape and surrounding skin of the nasal defects, nasolabial fold flaps, modified rhomboid flaps, bilobed flaps or frontal nasal flaps were chosen to repair skin and soft tissue defects. Results Of the 65 patients with nasal skin tumors, 38 had basal cell carcinoma, 20 pigmented nevus, 5 keratoacanthoma, and 2 had squamous cell carcinoma. The lengths of the defects after resection were all below 2.5 cm. Nasolabial fold flaps were used in 32 cases, modified rhomboid flaps in 16, bilobed flaps in 12, and frontal nasal flaps in 5. All the flaps survived after the surgery, and no obvious deformation of the nose was observed. No recurrence was observed during 1 year of follow?up. Conclusion For skin defects with the length ≤ 2.5 cm after resection of nasal skin tumors, nasolabial fold flaps, modified rhomboid flaps, bilobed flaps and frontal nasal flaps can be used to repair wounds, with satisfactory efficacy.
