Tunnel Flaps Were Used To Repair Defects After Excision Of External Nasal Tumors

Objective: To explore the outer nasal tumors surgically repaired summary manner and prognosis, Statistical study of the fast pathologic positive rate of tumor resection margin in patients with basal cell carcinoma and squamous cell carcinoma, provide more treatment for clinical experience.Methods: A retrospective analysis of 76 patients with nasal tumors exception from June 2012 to June 2015 Yuhuangding of Otolaryngology Head and Neck Surgery Hospital treated, including 12 cases of benign and malignant tumors 64 cases, 51 cases of male, 25 female, aged from 31 to 90 years; a history of 6 months to 50 years. Bridge of the nose area two cases; 40 cases of nasal dorsum area, the outer edge of the nose and facial continuation of the community in 11 cases, one case of melanoma. Nose tip region 34 cases, around the nose of the 21 cases, including five cases involving the nose ditch. Columella four cases, spread to part of the nasal tip skin. Nine cases of nasal tip, where the hemangioma. 60 Exceptions nasal tumors confined to the skin layer, 12 cases involving the dorsum cartilage, nose hole infringement skin or mucous membranes in 4 cases. The outer edge of the nose and lower eyelids in 1 case. Tumor resection defect size from 0.8cm × 1.5cm ~ 2,0cm × 3.5cm range. According to the tumor is located outside of the nose portion and the depth of invasion, involvement of different structures, the design of different skin flaps, the survival rate was observed. By basal cell carcinoma, squamous cell carcinoma, melanoma patients after resection of the tumor pathology fast the outer edge of different distances, corresponding to tumor discuss security boundary distance.Results: 74 patients of uniform flap repair survived, two months after the appearance of the natural skin color is similar to high patient acceptance, followed up for 3 months to 2 years, 2 cases of squamous cell carcinoma recurrence, again surgery, postoperative radiotherapy. Where in the pedicle flap in 70 cases, one case of full-frontal axis defects dorsum flap necrosis after using nasal dorsum bilateral adjacent flap survival rate of 98.6%. Free Flap six cases, one case free composite ear flap free edge alar necrosis, the survival rate was 83.3%. Rapid pathological positive rate difference from basal cell carcinoma tumors different from the outer edge of statistical significanceConclusion: pedicle flap survival rate is higher than the survival rate of defect free flap surgery, basal cell carcinoma and squamous cell carcinoma were rapid positive rate of pathological tumor edge from different distances in statistically significant, there is scope for removal certain significance.
