异种（牛）脱细胞真皮基质修复膜在耳鼻咽喉头颈外科术后缺损修复的应用

目的〓〖HTK〗探讨异种（牛）脱细胞基质修复膜在耳鼻咽喉头颈外科术后缺损修复的临床效果。〖HTW〗方法〓〖HTK〗利用修复膜对64例患者术后缺损进行一期修复，其中非肿瘤疾病11例，头颈部肿瘤53例。所有患者术后根据局部分泌物、脓液培养及药敏结果应用敏感抗生素，同时给予对症处理，保持修复膜湿润，咽喉肿瘤及颈段食道癌的患者进行鼻饲，不过早经口进食。〖HTW〗结果〓〖HTK〗 所有患者出院时经检查，60例皮肤或黏膜缺损修复一期愈合；下咽癌、喉癌各1例患者术后出现咽漏，经局部换药对症处理后愈合；1例喉癌患者术后出现喉漏，经局部换药对症处理后愈合。均未发现排斥、过敏等反应。〖HTW〗结论〓〖HTK〗异种(牛)脱细胞真皮基质修复膜为修复耳鼻咽喉头颈外科术后的缺损提供了一种新的方法，手术操作简便，效果良好。

Heterogenerty (cattle) acellular dermal matrix repairing mucosa in otolaryngology reconstruction surgeries

Objective〓〖WTBZ〗To explore the clinical effect of heterogeneity (cattle) acellular deunal matrix in mucosa defect repair in otolaryngology surgeries. 〖WTHZ〗Methods〓〖WTBZ〗64 cases of mucosa defect were treated with heterogeneity acellular deunal matrix, 53 of them were neoplasms. After the operations, patients were given antibiotics based on secretions or pus, also the acellular dermis should be kept moist and patients with neck esophageal squamous carcinoma or hypopharynx and larynx carcinoma received nasal feeding. 〖WTHZ〗Results〓〖WTBZ〗60 cases were healed. 1 case of hypopharynx and 1 of larynx carcinoma infected by pharynx fistula, and 1 case of larynx carcinoma infected by larynx fistula were healed after dressing change and expectant treatment. No exclusiveness and irritation were found during the treatments. 〖WTHZ〗Conclusion〓〖WTBZ〗Heterogeneity acellular deunal matrix is easily obtained and is effective in repairing mucosa defects.
