Transoral Flexible Laser Posterior Transverse Cordotomy with Blue Laser: A Case Describing a New Surgical Approach.

The posterior transverse cordotomy (PTC) can be performed for posterior glottic stenosis (PGS) in the operating room through suspension laryngoscopy. This procedure requires adequate exposure of the vocal cords. An alternative PTC approach was carried out on a 56-year-old man without a view of the vocal cords during suspension laryngoscopy. After anteriorizing the hypertrophic tongue with a glide scope, the surgeon reached the vocal folds through a flexible nasofibroscopy with an operative channel. The adequate exposure of the posterior part of the vocal cords allowed the blue laser PTC through the operative channel in the cut setting. The postoperative outcomes were adequate in the follow-up period. This paper describes an alternative approach to PTC in a patient with PGS and several unsuccessful laryngeal exposures.
