Reconstruction of the nasal subunits after tumor resection

Introduction: A majority of the nods present for reconstruction are secondary to tumor excision. The objective is to analyze the efficacy of the reconstructive technique used to cover the defect after tumor exeresis according to the affected nasal anatomical subunit. Method: Retrospective study of the medical records of 118 patients submitted to resection of the nasal tumors at the Mário Penna Institute in Belo Horizonte/ MG from August 2012 to March 2017. Results: Incidence was higher in women (56%) and whites (54.3%) average age of 71.3 years. A total of 125 tumors were resected, and 122 nose reconstructions were performed. Basal cell carcinoma (90.4%) was the most prevalent nonmelanoma skin tumor, the most frequent solid histological subtype (33.6%). The techniques for reconstruction of defects that affect only one nasal subunit were mostly using the bilobed flap (26.5%). In complex nose reconstructions, the bilobed myocutaneous flap (45.8%) with extension to a glabella region (encompassing the procerus, corrugator and nasal muscles) was the most used, mainly in defects in the lower third of the nose. About 78 patients had cancer follow-up of more than one year, and 82 total sin tumors were evaluated. Seven (8.5%) Tumors retreated even after complete resection, and, among the six patients with compromised margins, only one (1.2%) relapsed. Conclusion: The reconstructive techniques used were effective for treating nasal skin cancer and coverage of defects after resection, with low rates of complication and recurrence
