A cutaneous flap from the cheek and a perichondrocutaneous free graft is used for closing a perforation of the nasal septum. The cutaneous flap is rotated to set into the defect covering one side of the perforation while the other side is covered with a free perichondrocutaneous graft, nutrified by vascular proliferation from the cutaneous flap. The anterior side of the auricular concha is used as donor site for the composite perichondrocutaneous graft. The cutaneous flap is divided after about four weeks. Twenty-eight patients have been operated on with this technique; 27 had a complete closure after an observation time of four to eight years. A biopsy three months after the operation showed that the perichondrium generated cartilage as supporting tissue. The technique was modified as using a labiobuccal mucosal flap showed unfavourable results.
采用脸颊皮瓣和带软骨膜的游离皮瓣修复鼻中隔穿孔。将皮瓣旋转至缺损处，覆盖穿孔的一侧，另一侧则用带软骨膜的游离皮瓣覆盖，该皮瓣通过皮瓣的血管增生获得营养。耳廓耳甲前部用作复合带软骨膜皮瓣的供区。约四周后切断皮瓣。28例患者采用该技术进行手术；27例在4至8年的观察期后实现完全闭合。术后三个月的活检显示，软骨膜生成软骨作为支撑组织。采用唇颊黏膜瓣的技术改良效果不佳。
