title: Minimally invasive surgery for posterior glottic stenosis.
abstract: Posterior glottic stenosis most commonly results from prolonged endotracheal intubation. The tube causes decubitus and perichondritis with a consequent scar tissue formation in the posterior commissure that often limits the abduction of the vocal cords. Many different surgical methods are known for the treatment, but in most cases temporary tracheostomy is required. We recommend a minimally invasive method to avoid tracheostomy, which is a very inconvenient state for the patient. The scar of the posterior commissure is excised endoscopically with the CO2 laser, and a modification of the endoextralaryngeal vocal cord laterofixation described by Lichtenberger is used to lateralize 1 or both vocal cords until the posterior commissure is completely reepithelialized. In this article we report on the first 5 cases. All patients had satisfactory airways immediately after the laterofixation procedure, which proved to be stable later on as well. In the cases of moderate stenosis, further scarring was prevented, and after the healing of the mucosa in the posterior glottic area, the laterofixation sutures were removed. The vocal cord mobility was recovered in the cases in which the cricoarytenoid joint was not fixed. In 1 case of severe stenosis (bilateral cricoarytenoid joint fixation), the procedure yielded only partial improvement.
