Intracordal Teflon injection is a widely accepted method for the treatment of glottic incompetence due to unilateral vocal fold paralysis. It can be performed transorally via direct or indirect laryngoscopy, as well as transcutaneously under laryngovideoscopy. However, these procedures still have their disadvantages. The technique we introduce is to perform the procedure transorally while using a curved injection needle under flexible laryngovideostroboscopic monitoring. With topical anesthesia, the patient can phonate naturally during the procedure. The surgeon can visualize the needle and injection site clearly under high-resolution flexible laryngovideostroboscopy. Stroboscopic examination during surgery enables the surgeon to monitor the improvement of vocal fold vibration. Twenty consecutive patients treated with this technique were studied. The preliminary results are satisfactory. The technique we introduce is an outpatient procedure with high applicability and low morbidity. This technique is a good, cost-effective alternative to standard operative direct laryngoscopy with injection.
声带内注射聚四氟乙烯是治疗单侧声带麻痹所致声门功能不全的一种广泛接受的方法。它可以通过直接或间接喉镜经口进行，也可以在喉镜视频检查下经皮进行。然而，这些操作仍有其缺点。我们介绍的技术是在软性喉镜频闪监测下经口使用弯曲注射针进行操作。采用表面麻醉，患者在操作过程中可以自然发声。在高分辨率软性喉镜频闪检查下，外科医生可以清楚地看到针头和注射部位。手术中的频闪检查使外科医生能够监测声带振动的改善情况。对连续20例采用该技术治疗的患者进行了研究。初步结果令人满意。我们介绍的技术是一种门诊手术，适用性高，发病率低。该技术是标准手术直接喉镜注射的一种良好的、性价比高的替代方法。
