Abstract
Tracheal end-to-end anastomosis is a reconstruction procedure after tracheal resection due to injury, stenosis, or malignant tumor. There is a risk of complications such as recurrent nerve palsy in addition to anastomotic stenosis and suture failure.
Nerve integrity monitoring is useful for intraoperative recurrent nerve monitoring, but signal errors can occur due to misalignment of the electrodes. In such cases, a method of directly sensing the movement of the posterior cricothyroid muscle by inserting a finger into the dorsal surface of the hypopharynx （laryngeal twitch method） has been used to confirm the function of the recurrent nerve.
We performed tracheal end-to-end anastomosis for tracheal stenosis after tracheostomy. We report the effectiveness of the laryngeal twitch method in preserving the function of the recurrent nerve.
