To evaluate the usefulness of resorbable polydioxanone plate attached to nasal septal cartilage in external septoplasty, to assess its mechanical stability until healing of cartilage fragments, and to describe the surgical technique and clinical experience.
External septoplasty with polydioxanone plate has been performed in 396 patients since 1996. Indications were severe septal deformities (usually posttraumatic). Surgery included removal of the quadrilateral cartilage and division into straight fragments, which were sutured to resorbable polydioxanone plate and replaced as a free graft. If the nasal septal cartilage was partly or completely missing because of prior surgery or trauma, the missing cartilage was supplanted with auricular conchal cartilage. The study settings were Medicent Linz, Linz, Austria, and the Ear, Nose, and Throat Department, General District Hospital Steyr, Steyr, Austria.
Functional and cosmetic outcomes were satisfactory. All patients experienced varying degrees of improvement in nasal blockage. There were no immediate (bleeding, septal hematomas, inflammatory reactions, or necrosis) or long-term (septal perforation, thickening of the nasal septum, or rejection of the implant) complications.
Use of polydioxanone plate attached to nasal septal cartilage facilitates surgical correction of severe septal deformities and supports the nasal dorsum until healing.
评估可吸收聚二氧六环酮板附着于鼻中隔软骨在外鼻鼻中隔成形术中的效用，评估其在软骨碎片愈合前的机械稳定性，并描述手术技术和临床经验。
自1996年以来，对396例患者实施了使用聚二氧六环酮板的外鼻鼻中隔成形术。适应症为严重鼻中隔畸形（通常为创伤后）。手术包括切除四边形软骨并将其分割成直的碎片，将这些碎片缝合到可吸收聚二氧六环酮板上并作为游离移植物进行复位。如果鼻中隔软骨因先前手术或创伤而部分或完全缺失，则用耳甲软骨替代缺失的软骨。研究地点为奥地利林茨的Medicent Linz以及奥地利施泰尔的施泰尔综合区医院耳鼻喉科。
功能和美容效果令人满意。所有患者的鼻塞均有不同程度改善。无即刻（出血、鼻中隔血肿、炎症反应或坏死）或长期（鼻中隔穿孔、鼻中隔增厚或植入物排斥）并发症。
使用附着于鼻中隔软骨的聚二氧六环酮板有助于严重鼻中隔畸形的手术矫正，并在愈合前支撑鼻背。
