本文对4只成狗采用同种异体软骨移植重建喉切除术后软骨支架研究,结果表明经过70％酒精制备的同种异体软骨可为受体耐受。组织学观察发现移植软骨有的保存良好,有的部分吸收,但仍保持原软骨形状,起到喉支架作用。4例术后全部恢复了正常呼吸功能并将此法应用于临床喉部分切除术后的修复,5例中之3例术后拔除气管套管,均恢复了喉正常呼吸功能,2例已能堵管。 In this paper, allograft cartilage transplantation was used to reconstruct the cartilage scaffold after laryngectomy in 4 dogs. The results showed that allograft cartilage prepared with 70% alcohol could be tolerated by the recipient. Histological observation found that some of the well-preserved cartilage transplantation, and some absorption, but still maintain the original cartilage shape, play the role of laryngeal scaffold. All 4 patients recovered normal respiratory function and applied this method to clinical partial throat resection. In 3 of 5 cases, tracheal cannula was removed after operation, and the normal laryngeal respiratory function was restored. Plugging tube.
