Objective To investigate the clinical epidemiological characteristics of external nasal mass, and analyze the repair methods and clinical effects of resected defects. Methods Clinical data of 34 patients with external nasal mass treated in our hospital from January 2010 to December 2020 were analyzed retrospectively. The analyzed data included location, size and pathological diagnosis of tumors, surgical and repair methods. Results Of all the 34 cases, the ratio of male to female was 1.125∶1, and the difference was statistically insignificant (P＞0.05). Among the external nasal malignancies, basal cell carcinoma was the most common (16 cases, 80%), and occurred in all age groups. The peak age of malignant tumors was the elderly population over 60 years old (15 cases, 75%). After complete resection, 15 cases were sutured directly, 7 cases were repaired with adjacent flap, 10 cases were repaired with nasolabial sulcus flap, and 2 cases were grafted with skin. During postoperative follow-up, 1 case received chemoradiotherapy and 2 received chemotherapy alone. Primary wound healing was achieved in 28 cases with basically symmetrical appearance and without obvious ventilation dysfunction. Second stage scar repair was performed in one case. Three cases were lost to follow-up, three died (due to old age), and two had unsatisfactory external nasal morphology. Conclusions The external nasal masses rarely recur after complete resection, and chemoradiotherapy is generally not required. On the basis of complete resection of the tumor, different repair methods can be flexibly applied according to the defect site and degree to reconstruct the nasal contour and maintain the integrity of the nasal shape and structure. The nasolabial sulcus flap is a common choice of treatment because of its convenient operation, few complications and satisfactory results.
