An extremely laterally positioned vocal cord can result in a large posterior glottal gap – an opening between the two vocal cords even when the functioning vocal cord is fully medialized. Agytenoid parameters of laryngeal airflow and subglottic pressure were measured. A 2-second segment of sustained vowel was used for perceptual analysis by means of a panel of voice adeuction and a rating system.

Privacy Policy Terms of Use. In the treatment of unilateral vocal cord paralysis, vocal fold medialization improves closure, facilitating entrainment of both vocal folds for improved phonation, and reinnervation is purported to maintain vocal fold bulk and stiffness. The Journal of Laryngology and Otology.

Patients without postoperative voice analysis were invited back for its completion. Vocal cord injection is ineffective for closing a large glottal gap. Glottal closure and symmetrical thyroarytenoid stiffness are two important functional characteristics of normal phonatory posture.

Combined arytenoid adduction and laryngeal reinnervation in the treatment of vocal fold paralysis.

In all tested parameters the extent of improvement was similar in both groups. A retrospective review of preoperative and postoperative voice analysis on all patients who adductioon arytenoid adduction alone adduction group or combined arytenoid adduction and ansa cervicalis to recurrent laryngeal nerve anastomosis combined group between and for the treatment of unilateral vocal cord paralysis.

This is accomplished by passing a suture between the muscular process of the arytenoid cartilage and the thyroid cartilage.

There were no episodes of airway obstruction requiring tracheostomy or implant extrusion. A suture is used to emulate the action of the lateral cricoarytenoid muscle and position the paralyzed vocal cord closer to the midline. Purchase access Subscribe to JN Learning for one year. Many cases of vocal cord paralysis result from trauma during surgery. One of the key functions of the larynx is phonationthe production of sound.

Views Read Edit View history. Arytenoid adduction is a surgical procedure used to treat vocal cord paralysis. The role of laryngeal reinnervation in the treatment of unilateral vocal cord paralysis remains to be established. Arytenoid adduction is more technically challenging than either vocal cord injection or adduuction thyroplasty and has a high learning curve. Objective outcome measures include mean and maximum phonation time, phonotory airflow, and signal-to-noise ratio.

It is especially indicated for the case of a wide, glottal chink and a difference in the level of the two cords. 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. Arytenoid adduction with or without medialization thyroplasty significantly improves quality of life for patients with vocal cord paralysis.

Physiologically, the glottis is closed by intrinsic laryngeal muscles such as the lateral cricoarytenoidthyroarytenoidand interarytenoid muscles.

This page was last edited on 16 Novemberat The surgical procedure is rather simple, easy, and allows adjustment of adductioh degree of arytenoid adduction during surgery to produce the best voice obtainable. The muscle process is pulled by two nylon sutures in simulation of the functions of the lateral cricoarytenoid muscle and the lateral thyroarytenoid muscle.

Arytenoid adduction is often performed in conjunction with medialization thyroplasty. Sign in to access your subscriptions Sign in to your personal account.

Arytenoid adduction

Orphaned articles from February All orphaned articles. The paralyzed vocal cord may rest close to or far from the midline. 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.

Subjective analysis confirms marked improvement in laryngeal adduxtion in the form of speech, swallowing, and respiration. This results in a vertical gap between the two vocal cords that cannot be resolved using vocal cord injection or medialization thryoplasty.

Both groups had significant perceptual improvement of adductikn quality. Our website uses cookies to enhance your experience. A combination of medialization and reinnervation would be expected to further improve vocal quality over medialization alone. This allows the two vocal cords to meet and can improve speaking and swallowing ability for affected patients.
