There were no episodes of airway obstruction requiring tracheostomy or implant extrusion. Create a free personal account to access your subscriptions, sign up for alerts, artyenoid more. Physiologically, the glottis is closed by intrinsic laryngeal muscles such as the lateral cricoarytenoidthyroarytenoidand interarytenoid muscles.
It has been suggested that this is because arytenoid adduction directly rotates the arytenoid cartilage and thus more actively medializes the posterior aspect of the vocal cord. Create a free personal account to download free article PDFs, adduvtion up for alerts, and more.
Combined arytenoid adduction and laryngeal reinnervation in the treatment of vocal fold paralysis.
A suture is used to emulate the action of the lateral cricoarytenoid muscle and position the paralyzed vocal cord closer to the midline. Orphaned articles from February All orphaned articles. Evaluation included symptomatic improvement in hoarseness, aspiration, dysphagia, dyspnea, and the radiographic documentation of pneumonia. From Wikipedia, the free encyclopedia. A 2-second segment of sustained vowel was used for perceptual analysis by means of a panel of voice professionals and a arutenoid system.
Future directions will focus on determination of those patients best served by arytenoid adduction. Aerodynamic parameters of laryngeal airflow and subglottic pressure were measured. Objective outcome measures include mean and maximum phonation time, phonotory airflow, and signal-to-noise ratio.
Closure and mucosal wave improved significantly in both groups. Create a personal account to register for email alerts with links to free full-text articles.
Phonation requires the vocal cords to be adducted positioned towards the midline so that they can meet and vibrate together as air arytenoic expelled between them. Patients undergoing arytenoid adduction with or without silastic medialization for unilateral vocal cord aryfenoid were entered into a prospective data base.

A combination of medialization and reinnervation would be expected to further improve vocal quality over medialization alone. The paralyzed vocal cord may rest close to or far from the midline.

Patients without postoperative voice analysis were invited back for its completion. It is especially indicated for the case of a wide, glottal chink and a difference in the adytenoid of the two cords. This results in a vertical gap between the two vocal cords that cannot be resolved using vocal cord arytdnoid or medialization thryoplasty.
Options for surgical treatment of vocal cord paralysis include vocal cord injection, medialization thyroplasty, and arytenoid adduction. The surgical procedure is rather simple, easy, and allows adjustment of the degree of arytenoid adduction during surgery to produce the best voice obtainable.
Arytenoid Adduction for Unilateral Vocal Cord Paralysis
In the treatment of unilateral vocal cord paralysis, vocal fold medialization improves closure, facilitating entrainment of both adductjon folds for improved phonation, and reinnervation is purported to maintain vocal fold bulk and stiffness.
There were 9 patients in the adduction group and 10 patients in the combined group. This page was last edited on 16 Novemberat Objective analysis confirms improvement in voice parameters.
However, arduction adduction is preferred in cases where there is a large posterior glottal gap or vertical misalignment between the vocal folds. The suture placed in the arytenoid adduction procedure mimics the action of the lateral cricoarytenoid muscle and pulls the vocal process of the arytenoid cartilage medially and inferiorly. This allows the two vocal cords to meet and can improve speaking and swallowing ability for affected patients.
