In particular surgical situations, part of the airway wall may have to be excised for different reasons, perhaps because of a large tumor or extensive scar tissue. The repair of large laryngotracheal defects, impossible to reconstruct with segmental resection and end-to-end anastomosis or to repair with existing adjacent tissue, is a challenge. A prerequisite for reconstruction of such defects is a graft composed of well-vascularized mucosal lining and a supportive framework to keep the airway patent. A three-stage procedure, based on the creation of an autogenous mucosal cyst, has been developed and used clinically in a series of patients. The three most recent patients who have undergone reconstruction with pedicled muscle Proplast mucosa grafts are presented. In two of the patients, large unilateral laryngeal tumors were removed and the third had a large patent tracheostoma.
在某些特定的手术情况下，出于不同原因可能需要切除部分气道壁，这或许是由于存在大的肿瘤或广泛的瘢痕组织。修复大的喉气管缺损是一项挑战，因为无法通过节段性切除和端端吻合进行重建，也无法利用现有的相邻组织进行修复。重建此类缺损的一个先决条件是要有一个由血供良好的黏膜内衬和维持气道通畅的支撑框架组成的移植物。一种基于自体黏膜囊肿形成的三阶段手术方法已被研发出来并在一系列患者中临床应用。本文介绍了最近接受带蒂肌肉Proplast黏膜移植物重建手术的3例患者。其中2例患者切除了大的单侧喉肿瘤，第3例患者有一个大的开放性气管造口。
