RESUMEN
Objective:To investigate clinical efficacy of tunneled subcutaneous pedicle flaps in the repair of ipsilateral nasal alar defects.Methods:A total of 20 patients with nasal alar defects after excision of basal cell carcinoma, which were repaired with ipsilateral tunneled subcutaneous pedicle flaps, were retrospectively collected from January 2018 to January 2020. There were 11 male patients and 9 female patients, with an average age of 60.6 years (range, 48 - 76 years) . According to clinical manifestations, the basal cell carcinoma lesions could be classified into 3 types: nodular-ulcerative type (13 cases) , superficial type (4 cases) and pigmented type (3 cases) , and the skin lesions varied from 0.4 cm × 0.5 cm to 0.9 cm × 1.1 cm in size. All the patients received extended surgical resection of basal cell carcinoma, and nasal alar defects were repaired with tunneled subcutaneous pedicle flaps, with the size of flaps ranging from 0.7 cm × 0.8 cm to 1.2 cm × 1.4 cm.Results:All flaps survived successfully, the nasal alar defects were completely repaired, and all wounds healed primarily. During the postoperative follow-up of 6 - 24 months, neither recurrence of tumors nor obvious scar hyperplasia occurred on the nasal ala, and nasal morphology and appearance were favorable.Conclusion:The tunneled subcutaneous pedicle flap can be used for the repair of ipsilateral nasal alar defects following excision of tumors or other lesions, resulting in favorable therapeutic outcomes and aesthetic appearance.
RESUMEN
Objective@#To sum up the repair techniques of secondary alar deformity after the first phase reconstruction of alar defect.@*Methods@#From January 2010 to December 2017, 17 patients with secondary alar deformity were included. Secondary alar deformities after the first stage reconstruction of alar defect included the abnormalities of alar groove line, absence of alar-cheek groove and the notch of alar rim. Z-plasty, V-Y advanced flaps, local skin flap and other technologies were introduced to repair details.@*Results@#Infection was found in one case of the reconstruction of the alar-cheek groove and the wound was healed by treatment. There was no necrosis occurred in other flap. The shape of the alar was satisfactory and the anterior nostril was not narrow. Patients were followed up for 1 month to 1 year. The average follow-up time was 5 months. No recurrence of nasal alar tumor was found. The patients were satisfied with the appearance.@*Conclusions@#The symmetrical and satisfactory nasal shape can be obtained with local flaps such as Z-plasty, V-Y advancement of flaps for secondary alar deformities.
