摘要目的 总结脱细胞真皮基质黏膜组织补片(acellular dermal matrix,ADM)应用在修复咽部组织缺损中的手术配合要点.方法 对7例咽部恶性肿瘤患者行喉全切除或喉咽全切除术,将ADM缝在椎前筋膜上重建喉咽后壁,用胸大肌肌皮瓣重建喉咽前壁和侧壁,重建密闭腔道.结果 7例患者术后未发生排异反应,无咽瘘,创面均黏膜化,切口全部一期愈合.结论 ADM来源方便,组织相容性好,厚薄适宜,手术操作简便,可联合胸大肌肌皮瓣或其他颈部组织修复咽部环周缺损,是一种新的安全有效的修复材料.手术前的精心准备,术中熟练的配合是确保手术成功的关键.

abstractsObjective To summarize the key point of application of acellular dermal matrix(ADM)in operative cooperation of pharyngeal tissue repair.Methods In order to rebuild the air-tight cavity,ADM was sewn to the anterior vertebrae fascia in 7 patients with pharyngeal malignant tumor undergoing total laryngectomy or pharyngolaryngectomy to rebuild the posterior wall of the laryngopharynx.Meanwhile the muscular flap of the pectoralis major Was used to rebuild the anterior and lateral walls of the laryngopharynx.Results There was no reject reaction or pharyngeal fistula in these 7 cases and the wound surface were all mucous membranized.All the incisions reached the primary healing.Conclusions ADM is easy to get and possesses good histocompatibility and compatible thickness.It is easy to be managed during operation and can modify the peripharyngeal defect with the combination of muscular flap of the pectoralis major or any other neck tissue.Strict nursing preparation before operation and perfect cooperation during operation are key steps to complete the surgery successfully.
