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

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. In the treatment of unilateral vocal cord paralysis, vocal fold medialization improves closure, facilitating entrainment of aryteboid vocal folds for improved phonation, and reinnervation is arytenold to maintain vocal fold bulk and stiffness.

Arytenoid adduction is more technically challenging than either vocal cord injection or medialization thyroplasty and has a high learning curve. An extremely laterally positioned vocal cord can result in a large posterior glottal gap – an opening between the two vocal addcution even when the functioning vocal cord is fully medialized. Glottal closure and symmetrical thyroarytenoid stiffness are two important functional characteristics of normal phonatory posture. A retrospective review of preoperative and postoperative voice analysis on all patients who underwent arytenoid avduction 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.

Arytenoid adduction – Wikipedia

The Journal of Laryngology and Otology. Damage to these nerves results in vocal cord paralysis – the reduced mobility and inability to adduct one or both vocal cords. Evaluation included symptomatic improvement in hoarseness, aspiration, dysphagia, dyspnea, and the radiographic documentation of pneumonia.

Options for surgical treatment of vocal cord paralysis include vocal cord injection, medialization thyroplasty, and arytenoid adduction. Patients undergoing arytenoid adduction with or without silastic medialization for unilateral vocal cord paralysis were entered into a prospective data base.

An Evolving Clinical Concept”. 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.

The study was performed to evaluate our experience in 28 patients undergoing arytenoid adduction as part of their surgical rehabilitation of unilateral vocal cord paralysis. Aerodynamic parameters of laryngeal airflow and subglottic pressure were measured. Purchase access Subscribe to JN Learning for one adduchion.

Arytenoid adduction with or without medialization thyroplasty significantly improves quality of life for patients with vocal cord paralysis. Phonation requires the vocal cords to be adducted positioned towards the midline so that they can meet and vibrate together as air is expelled between them.

This allows the two vocal cords to meet and can improve speaking and swallowing ability for affected patients.

Our website uses cookies to enhance your experience. The paralyzed vocal cord may rest on a different plane than the opposite vocal cord. Subglottic pressure remained unchanged in both groups. A combination of medialization and reinnervation would be expected to further improve vocal quality over medialization alone.

Retrieved from ” https: One of the key functions of the larynx is phonationthe production of sound. A 2-second segment of sustained vowel was used for perceptual analysis by means of a panel of voice professionals and a rating system.

It is especially indicated for the case of a wide, glottal chink and a difference in the level of the two cords. Videostroboscopic measures of glottal closure, mucosal wave, and symmetry were rated.
