Abstract
Glottis dilatation is required to manage dyspnea due to bilateral abductor vocal cord paralysis. Since the method of vocal cord laterofixation reported by Ejnell et al. is relatively non-invasive and has benefits related to postoperative laryngeal function, it has been considered as the first choice in treating case of bilateral abductor vocal cord paralysis in recent years. However, two problems with this method need to be resolved. One is the difficulty of getting a good endolaryngeal view in the case of poor laryngeal extension, and the other is how to prevent looseness in the nylon knot on the thyroid lamina.
To resolve these problems, we used a rigid endoscope with Ejnell's method to get a clear endolaryngeal view instead of the usual microscope. We also used a titanium plate called an ”Endobottun” as a spacer between the thyroid lamina and the nylon knot to prevent looseness.
