Evaluation included symptomatic improvement in hoarseness, aspiration, dysphagia, dyspnea, and the radiographic documentation of pneumonia.

Objective analysis confirms improvement in voice parameters.

Damage to these nerves results in vocal cord paralysis – the reduced mobility and inability to adduct one or both vocal cords.

The paralyzed vocal cord may rest close to or far from the midline. 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.

Future directions will focus on determination of those patients best served by arytenoid adduction.

In the adducction 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 muscle process is pulled by two nylon sutures in simulation of the functions of the lateral cricoarytenoid muscle and the lateral thyroarytenoid muscle. Closure and mucosal wave improved significantly in both groups. It is especially adytenoid for the case of a wide, glottal chink and a difference in the level of the two cords.

There were no episodes of airway obstruction requiring tracheostomy or implant extrusion. The paralyzed vocal cord may rest on a different plane than the opposite vocal cord.

Retrieved from ” https: Subjective analysis confirms marked improvement in laryngeal function in the form of speech, swallowing, and respiration. Improvement of voice after surgery was dramatic in all of arytrnoid patients who were operated on. The Journal of Laryngology and Otology. Both groups had significant perceptual improvement of voice quality.

A 2-second segment of sustained vowel was used for perceptual analysis by means of a panel of voice professionals and a rating system. Patients without postoperative voice analysis were invited back for its completion.

Arytenoid Adduction for Unilateral Vocal Cord Paralysis

One of the key functions of the larynx is phonationthe production of sound. Vocal cord injection is ineffective for closing a large glottal gap.

A combination of medialization and reinnervation would be expected to further improve vocal quality over medialization alone. Views Read Edit View history. 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.

Glottal closure and symmetrical thyroarytenoid stiffness are two important functional characteristics of normal phonatory posture. Our website uses cookies to enhance your experience. 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 Annals of Otology, Rhinology, and Laryngology.

Objective outcome measures include mean and maximum phonation time, phonotory airflow, and signal-to-noise ratio. Aerodynamic parameters of laryngeal airflow and subglottic pressure were measured.

Arytenoid adduction as an adjunct to type I thyroplasty for unilateral vocal cord paralysis.

The arytenoid adduction procedure alleviates these symptoms by manually positioning the paralyzed vocal cord towards the midline. Arytenoid adduction is often performed at the same time as a medialization thyroplasty.

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. An Evolving Clinical Concept”. Arytenoid adduction with or without medialization thyroplasty significantly improves quality of life for patients with vocal cord paralysis.

Arytenoid adduction is more technically challenging than either vocal cord injection or medialization thyroplasty and has a high learning curve.
