The purpose of this investigation was to exclude abductor disturbance and to maintain phonation during recurrent laryngeal nerve paralysis through a new surgical design. This new method consists of implantation of the ansa hypoglossi and sternothyroid muscle pedicle which has been shown to provide sufficient abductor function in a recent publication, and the selective severance of the abductor branch after neurorrhaphy of the recurrent laryngeal which is shown to be a sufficient adductor function in another study. The recovery of sufficient abductor function during inspiration and dyspnea was 67% and 89% of adductor function with phonation. However, after cutting an adductor nerve branch of the recurrent laryngeal nerve in cases of insufficient abduction, the vocal cord on the operated-on side regained abduction during inspiration. The effect of the ansa hypoglossi and sternothyroid muscle pedicle is also discussed.
本研究的目的是通过一种新的手术设计来排除外展肌功能障碍并在喉返神经麻痹期间维持发声。这种新方法包括植入舌下神经袢和胸骨甲状肌蒂，最近的一项研究表明，这可提供足够的外展肌功能；以及在喉返神经神经缝合术后选择性切断外展肌分支，另一项研究表明，这可提供足够的内收肌功能。吸气和呼吸困难期间足够的外展肌功能恢复分别为发声时内收肌功能的67%和89%。然而，在 abductin 不足的病例中切断喉返神经的内收肌神经分支后，手术侧声带在吸气时恢复了外展。还讨论了舌下神经袢和胸骨甲状肌蒂的作用。
