Patients without postoperative voice analysis were invited back for its completion. Views Read Edit View history. 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.

The recent use of type I thyroplasty has resulted in improvements in voice, swallowing, and respiration.

Patients undergoing arytenoid adduction with or without silastic medialization for unilateral vocal cord paralysis were entered into a prospective data base.

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

Vocal cord injection is ineffective for closing a large glottal gap. Purchase access Subscribe to the journal.


Evaluation included symptomatic improvement in hoarseness, aspiration, dysphagia, dyspnea, and the radiographic documentation of pneumonia. The paralyzed vocal cord may rest close to or far from the midline.

Objective analysis confirms improvement in voice parameters. Get free access to newly published articles Create a personal account or sign in to: Closure and mucosal wave improved significantly in both groups.

Arytenoid adduction is often performed in conjunction with medialization thyroplasty. Sign in to save your search Sign in to your personal account. The surgical procedure is rather simple, easy, and allows adjustment of the degree of arytenoid adduction during surgery to produce the best voice obtainable.

This article is an orphanas no other articles arytwnoid to it. The suture placed in the arytenoid adduction procedure adductiob the action of the lateral cricoarytenoid muscle and pulls the vocal process of the arytenoid cartilage medially and inferiorly.

Many cases of vocal cord paralysis result from trauma during surgery.

This is accomplished by passing a suture between the muscular process of the arytenoid cartilage and the thyroid cartilage. However, arytenoid adduction is preferred in cases where there is a large posterior glottal gap or vertical adductioon between the vocal folds.

There were 9 patients in the adduction group and 10 patients in the combined group. An Evolving Clinical Concept”. Create a free personal account to download free article PDFs, sign up for alerts, customize your arytsnoid, and more.

A combination of medialization and reinnervation would be expected to further improve vocal quality over medialization alone. 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.

From Wikipedia, the free encyclopedia. Subglottic pressure remained unchanged in both groups. Glottal closure and symmetrical thyroarytenoid stiffness are two important functional characteristics of normal phonatory posture. Objective evaluation included mean phonatory air flow and acoustic analysis. Create a free personal account to access your subscriptions, sign up for alerts, and more. Physiologically, the glottis is closed by intrinsic laryngeal muscles such as the lateral cricoarytenoidthyroarytenoidand interarytenoid muscles.

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.
