Unilateral recurrent laryngeal nerve paralysis causes the vocal cord to atrophy, leading to glottic incompetence. The voice is characterized by hoarseness, breathlessness, rapid air escape, ineffective cough and aspiration. Traditional treatments of unilateral vocal cord paralysis include intracordal injection, laryngeal framework surgery, and laryngeal reinnervation for medialization of the vocal cord. In this paper we report on a new technique of transcutaneous intracordal silicon injection in which the injection is made through the thyroid lamina under local anesthesia monitoring fiberscopy. We performed this procedure on 30 patients with unilateral vocal cord paralysis and later evaluated their post-operative voice. The silicon injection resulted in improvement of vocal quality, favorable clearance of sputum, and aspiration control. We found that, since it can be performed under local anesthesia without hospitalization, transcutaneous intracordal silicon injection should be performed as a therapy for treating unilateral vocal cord paralysis.
单侧喉返神经麻痹会导致声带萎缩，进而引起声门功能不全。其声音特点为声音嘶哑、呼吸急促、气流快速逸出、咳嗽无力及误吸。单侧声带麻痹的传统治疗方法包括声带内注射、喉框架手术以及使声带内移的喉再支配手术。在本文中，我们报告了一种经皮声带内硅注射新技术，即在局部麻醉监测纤维喉镜下通过甲状软骨板进行注射。我们对30例单侧声带麻痹患者实施了该手术，随后评估了他们术后的声音情况。硅注射改善了嗓音质量，有利于痰液清除及控制误吸。我们发现，由于经皮声带内硅注射可在局部麻醉下进行且无需住院，应将其作为治疗单侧声带麻痹的一种疗法。
