Laryngeal Reinnervation Versus Thyroplasty in Patients With Vocal Fold Weakness.

This medialisation/augmentation technique is a static technique, performed under local anaesthesia that aims to improve the positioning of the paralysed vocal fold. It uses a silastic implant readily available in different sizes according to size of larynx and gender of the patient. The correct size can be determined intraoperatively by using a measuring device while listening and visualising the larynx with flexible fiberoptic scope simultaneously.

For laryngeal reinnervation, ansa cervicalis to recurrent laryngeal nerve repair technique will be used. In this technique, the functioning ansa cervicalis nerve that overlies the internal jugular vein and the distal stump of injured recurrent laryngeal nerve (RLN) will be identified and anastomosed without tension (Crumley RL.
