Application of local flaps in repair of nasal defects after excision of small cutaneous malignant tumors / 中华皮肤科杂志

ABSTRACT

Objective To investigate the methods for repairing skin defects after excision of small cutaneous malignant tumors at the lower one third part of nose and their clinical effects.Methods Lesions of small cutaneous malignant tumors at lower one third part of the nose were removed in 54 patients.Intraoperative pathology was performed to confirm the absence of survival carcinoma tissues after resection.According to the site,size,shape and neighborous skin status of defects,bilobed flaps,two-side rotation flaps and nasolabial flaps were selected to repair nasal skin tissue defects.Results There were 39(72.22%) cases of basal cell carcinoma, 9(16.67%) squamous cell carcinoma, 6(11.11%) keratoacanthoma.Skin defects after tumor removal were situated at the lower one third part of nose in all cases with less than 2.0 cm in diameter.Bilobed flaps were used to repair skin defects in 20 cases.rotation flaps in 2 cases,and nasolabial flap in 32 cases.As a result,all flaps survived and no obvious deformation of nose was observed in these cases.No recurrence occurred in a 5-year follow-up.Conclusion A satisfactory repair of skin defects at the lower one third part of nose with a diameter of less than 2.0 cm is achieved with bilobed flaps,two-side rotation flaps and nasolabial flaps.
