[Surgical treatment of middle laryngostenoses of paralytic etiology via extralaryngeal approach].

A method of treatment of middle laryngostenosis of paralytic etiology with laterofixation of the vocal fold is proposed. The technique includes an extralaryngeal approach to the thyroid cartilage plate from the front, subpericartilaginous resection of the vocal process of the arytenoids cartilage with dissection of the internal cricothyroid muscle and most of the thyroarytenoid muscle; placement of a part of the autocartilage under the anterior third of the vocal fold; divertion of the elastic cone with the vocal fold by ligation and tightening ligatures on the autotransplant put on the plate of the thyroid cartilage. Laryngostereotopometry used by the authors allows three-dimensional localization of the necessary point in the larynx and its topometric characteristics of its position in persons with different figure and form of the neck.
