We report a technique for medialization of a paralyzed vocal cord using a Gore-Tex (expanded polytetrafluoroethylene) implant inserted under local anesthesia via a cervical incision. Gore-Tex is an expanded form of Teflon. It is used in vascular surgery (vessel repair) and esthetic surgery (particularly to increase lip volume). In esthetic surgery, the development of inflammatory processes difficult to control have been observed with teflon and appear to be less frequent with Gore-Tex due to the absence of free particles in the expanded form. The minimally invasive technique is simple and reproducible and can be performed under local anesthesia. We report a series of 9 cases operated from October 1995 to October 1997. During this period, this technique predominated (two other patients had Teflon injections). Excepting one case of extrusion of the implant material, vocal results were very satisfactory, based on both subjective and objective analysis of vocal parameters. The contribution of this technique in comparison with the reference endoscopic techniques (Teflon, collagen) and surgical techniques (silicone, cartilage) is discussed. Early results would suggest that Gore-Tex implantation can be used in the more severe forms due to vocal cord paralysis in the lateral position.
我们报告一种在局部麻醉下经颈部切口植入戈尔特斯（膨体聚四氟乙烯）来使麻痹声带内移的技术。戈尔特斯是特氟龙的一种膨胀形式。它用于血管外科手术（血管修复）和美容手术（特别是增加唇部体积）。在美容手术中，已观察到使用特氟龙时会出现难以控制的炎症过程，而由于膨胀形式中不存在游离颗粒，戈尔特斯出现这种情况的频率似乎较低。这种微创技术简单且可重复，可在局部麻醉下进行。我们报告了1995年10月至1997年10月期间手术的9例病例。在此期间，该技术占主导地位（另外两名患者接受了特氟龙注射）。除1例植入材料挤出外，基于对嗓音参数的主观和客观分析，嗓音结果非常令人满意。讨论了该技术与参考内镜技术（特氟龙、胶原蛋白）和外科技术（硅胶、软骨）相比的贡献。早期结果表明，戈尔特斯植入可用于因声带麻痹处于外侧位置的更严重情况。
