RESUMO
<p><b>OBJECTIVE</b>To evaluate the application of acellular dermal matrix (ADM) in the reconstruction of defect after head and neck tumor resection.</p><p><b>METHODS</b>A total of 75 cases applied with ADM after head and neck tumor resection were reviewed. There were 47 cases of laryngeal carcinoma (glottic 41, supraglottic 3, and infraglottic 3), 5 cases of hypopharyngeal carcinoma, 11 cases of maxillary sinus carcinoma, 9 cases of oral cavity tumor, 3 cases of cervical trachea tumor. Among them 25 cases of laryngeal carcinoma, 4 cases of hypopharyngeal carcinoma, 7 cases maxillary carcinoma, 6 cases oral carcinoma, and one case of cervical trachea malignancy received postoperative adjuvant chemoradiotherapy. The patients were postoperatively followed up from 2 weeks to 3 years.</p><p><b>RESULTS</b>Among 75 cases, 65 cases, including 40 cases of laryngeal carcinoma, 4 cases of hypopharyngeal carcinoma, 9 cases of oral cavity tumor, 9 cases of maxillary carcinoma and 3 cases trachea tumor, presented with good wound healing without any complication within 3 months; the 47 patients with tracheotomy were decannulated successfully; 2 cases of laryngeal carcinoma and 1 case of hypopharyngeal carcinoma were complicated with pharyngeal fistula, which healed with dressing change, followed by decannulation; 5 cases had laryngeal stenosis and decannulation failed in these patients; and 3 cases of maxillary carcinoma had wound infection.</p><p><b>CONCLUSION</b>ADM application is a easy and feasible method for the repair of the defect after head and neck tumor resection.</p>
