Abstract

This study was conducted to describe the results of rhinoplasty after resection of basal cell carcinoma in the nasal alar area. This is a descriptive research on 34 patients including 18 male patients and 16 female patients, aged from 27 to 94, who underwent nasal alar reconstruction surgery after removal of basal cell carcinoma at Vietnam National Cancer Hospital from July 2017 to July 2023. Results were assessed during hospital stay and 6 months postoperative. The defect after resection of the tumor is from 0.9 to 81cm2 in size, including 13 cases of simple alar defect, 5 cases including the alar and tip, 11 cases including the alar, ipsilateral nasal sidewall and cheek, 5 cases of wide defect including the alar and surrounding units. The depth of the defect is from surface which only includes skin to the entire alar thickness, including 21 cases of superficial defects, 2 cases of deep defects (skin, subcutaneous tissue, alar cartilage) and 11 cases of transorganism defects (skin, alar cartilage, mucous membranes). These defects were covered by various methods: 1 case of direct closure, 2 cases of skin grafting, 12 cases of using local flaps, 11 cases of using nasolabial flaps (in which 3 cases were combined with auricular cartilage grafting), 6 cases of using forehead flap (in which 4 cases combined with auricular cartilage grafting) and 2 cases used both nasolabial flap and forehead flap combined with auricular cartilage grafting. After operation, 100% of flaps/grafts were completely alive. Follow-up after 6 months post-operative on 26 patients show good results on the shape of the nose, achieving the similarity in color, thickness, insignificant contraction and ensuring respiratory function. The results of the study show that reconstruction after removal of basal cell carcinoma in the alar area has good functional and aesthetic results, the choice of reconstruction method mainly depends on location, size and depth of the defects.
