当喉半侧麻痹时,已经麻痹的声带常常停留于中线位或半外展位(Semilateral position);如果声带停留于外展位时,这样的声门是较大了些,无论使声带接近或关闭声门,均有困难。因此,病人就不能说高音调的言语了。 为了矫正以上这种情况,已有多种手术方法,其中常用的就是切除甲状软骨的一侧翼板或其一部。 最近作者曾治疗一位年轻的女性患者,年32岁。她因为心脏手术后而发生的喉左侧半边麻痹,失声的时间已一年多。 When the larynx is paralyzed, the numbness that has been paralysed often stays at the midline or semilateral position; if the vocal cords stay at the outer booth, the glottis is larger, regardless of whether the vocal cords are approached or turned off. There are difficulties in the door. Therefore, patients cannot speak high-pitched speech. In order to correct this situation, there have been many surgical methods, of which one of the flaps or one part of the thyroid cartilage is often removed. The author recently treated a young female patient at the age of 32. Her numbness in her left side of the larynx, which occurred after her heart surgery, has been silenced for more than a year.
