Abstract: 【Abstract】 Objective To investigate efficacy and advantages of combined local flaps in repairing large defects in patients with nasal and perinasal non-melanoma skin cancers after Mohs micrographic surgery. Methods From March 2018 to November 2020, 11 patients with nasal and perinasal non-melanoma skin cancers, who underwent Mohs micrographic surgery followed by repair with combined local flaps, were collected from Department of Dermatology, the Second Hospital of Hebei Medical University. According to the location and size of postoperative defects, flaps were designed based on the nasal aesthetic subunit principle. For large defects that could not be directly sutured or covered by a single local flap, 2 or 3 kinds of flaps could be applied in combination, such as kite flap, modified diamond flap, nasolabial skin flap, bilobed skin flap, etc. Results Among the 11 patients, 10 were diagnosed with basal cell carcinoma and 1 with squamous cell carcinoma, and the area of defects ranged from 2.0 cm × 2.3 cm to 2.7 cm × 3.6 cm. After Mohs micrographic surgery combined with local skin flap repair, all skin flaps survived well without blood supply obstruction, the texture, color and contour of the skin flaps were similar to those of the surrounding normal skin, and no obvious scars were formed. During the postoperative follow-up of 4 to 32 months, no recurrence of the tumors occurred, and the patients was satisfied with the appearance. Conclusion To repair large defects using combined skin flaps of 2 or 3 kinds after Mohs micrographic surgery in patients with nasal and perinasal non-melanoma skin cancers can maintain the normal nasal and perinasal morphological structure and aesthetic appearance, and yield a satisfactory cosmetic effect.
