A 2-second segment of sustained vowel was used for perceptual analysis by means of a panel of voice professionals and a rating system. Options for surgical treatment of vocal cord paralysis adductioon vocal cord injection, medialization thyroplasty, and arytenoid adduction. 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.
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. Animal model studies suggest that combining the two procedures produces better outcomes than when performing either alone. Airflow decreased in both groups, but the decrease reached statistical significance only in the adduction group.
Arytenoid adduction is often performed in conjunction with medialization thyroplasty. Sign in to make a comment Sign in to your personal account. This allows the two vocal cords to meet and can improve speaking and swallowing ability for affected patients. Objective evaluation included mean phonatory air flow and acoustic analysis.
The arytenoid adduction procedure alleviates these symptoms by manually positioning the paralyzed vocal cord towards the midline.

Arytenoid adduction – Wikipedia
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 make a comment, download free article PDFs, sign up for alerts and more.

There were 9 patients in the adduction group and 10 patients in the combined group. Objective outcome measures include mean and maximum phonation time, phonotory airflow, and signal-to-noise ratio.
Surgical management of unilateral arytenojd cord paralysis has evolved over the last three decades. The muscle process is pulled by two nylon sutures in simulation of the functions of the lateral cricoarytenoid muscle and acduction lateral thyroarytenoid muscle.
Physiologically, the glottis is closed by intrinsic laryngeal aeytenoid such as the lateral cricoarytenoidthyroarytenoidand interarytenoid muscles. Purchase access Subscribe to the adduxtion. Patients without postoperative voice analysis were invited arytneoid for its completion.
However, arytenoid adduction is preferred in cases where there is a large posterior glottal gap or vertical misalignment between the vocal folds.
Glottal closure and symmetrical thyroarytenoid stiffness are two important functional characteristics of normal phonatory posture. This article is an orphanas no other articles link to it.

Arytenoid adduction as part of type I thyroplasty is a safe and effective procedure. A perceptual analysis was designed and completed.
Arytenoic directions will focus on determination of those patients best served by arytenoid adduction. Patients undergoing arytenoid adduction with or without silastic medialization for unilateral vocal cord paralysis were entered into a prospective data base.

Arytenoid adduction as an adjunct to type I thyroplasty for unilateral vocal cord paralysis.
Arytenoid adduction with or without medialization thyroplasty significantly improves quality of life for patients with vocal cord paralysis.
Subjective analysis confirms marked improvement in laryngeal function in the form of speech, swallowing, and respiration. The surgical procedure is rather simple, easy, and allows adjustment of the degree of arytenoid adduction during surgery to produce the arhtenoid voice obtainable.
A retrospective review of preoperative and postoperative voice analysis on all patients who underwent 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.
Subglottic pressure remained unchanged in both groups. Videostroboscopic measures of glottal closure, mucosal wave, and symmetry were rated.
