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 Annals of Otology, Rhinology, and Laryngology. Glottal closure and symmetrical thyroarytenoid stiffness are two important functional characteristics of normal phonatory posture.

Arytenoid adduction and medialization laryngoplasty.

Subglottic pressure remained unchanged in both groups. A 2-second segment of sustained vowel was used for perceptual analysis by means of a panel of voice professionals and a rating system. A perceptual analysis was designed and completed. Sign in to customize your interests Sign in to your personal account. Future directions will focus on determination of those patients best served asduction arytenoid adduction.

Arytenoid adduction is often performed at the same time as a medialization thyroplasty. The paralyzed vocal cord may rest close to or far from the midline.


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

The surgical procedure is rather simple, easy, and allows adjustment of the degree of arytenoid adduction during surgery to produce the best voice obtainable. 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.

Animal model studies suggest that combining the two procedures produces better outcomes than when performing either alone. A combination of medialization and reinnervation would be expected to further improve vocal quality over medialization alone.

Many cases of vocal cord paralysis result from trauma during surgery. Closure and mucosal wave improved significantly in both groups. An Evolving Clinical Concept”. A retrospective aryhenoid 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.

The arytenoid adduction procedure alleviates these symptoms by manually positioning the paralyzed adduciton cord towards the midline.

The role of laryngeal reinnervation in the treatment of unilateral adductoin cord paralysis remains to be established. Objective outcome measures include mean and maximum phonation time, phonotory airflow, and signal-to-noise ratio. Subjective analysis confirms marked improvement in laryngeal function in the form of speech, swallowing, and respiration.

There were 9 patients in the adduction group and 10 patients in the combined group. In all tested parameters the extent arytenod improvement was similar in both groups.

It is especially indicated for the case of a wide, glottal chink and a difference in the level of the two cords.
