Arytenoid adduction is a more invasive procedure than type I thyroplasty and is technically more difficult. It has been reported to carry somewhat greater surgical risks, including airway obstruction, joint dislocation, fistula, and carotid injury. 4, 5 A 2001 study compared outcomes of type I thyroplasty alone or in combination with arytenoid adduction in 237 patients.
Vocal Fold Medialization, Arytenoid Adduction, and Reinnervation Andrew Blitzer, Steven M. Zeitels, James L. Netterville, Tanya K. Meyer, and Marshall E. Smith 127 Restoration of vocal function with laryngeal framework sur-gery (laryngoplastic phonosurgery) was introduced at the beginning of the 20th century. Today, these procedures.
Arytenoid Adduction. Arytenoid adduction was described by Isshiki et al 5 as a way of mimicking the medializing effect of the lateral cricoarytenoid muscle on the vocal process. A paralyzed arytenoid tends to fall forward and laterally on the cricoid facet, shortening the AP length of the vocal fold and moving the arytenoid away from the midline.

This paper aims to describe the safe performance of the EAAS procedure resulting.
Background Arytenoidectomy is a permanent and irreversible surgical procedure whereby the laryngeal inlet is widened in its transverse axis, providing a larger airway for respiration. Arytenoidectomy is performed in cases of bilateral vocal fold immobility caused by either paralysis of the vocal cords or their fixation.
Adduction arytenopexy was designed as an innovation to arytenoid adduction, however the pragmatic issues regarding patient selection for these procedures has not been comprehensively assessed. A prospective examination was performed on 100 consecutive patients who had undergone laryngoplastic phonosurgical reconstruction for paralytic dysphonia.

The surgical technique used in these cats was similar to that described for dogs although the cricothyroid articulation was not disarticulated nor was the transverse arytenoid ligament transected.
The arytenoid adduction operation is an important surgical technique in the treatment of unilateral vocal fold paralysis. The advantages of arytenoid adduction over a type 1 thyroplasty operation include better closure of the posterior glottis and physiologic rotation of the cricoary-tenoid joint, leading to better height match during phona-.
Thyroplasty with arytenoid adduction, A sequential anesthesia technique for surgical repair of unilateral vocal fold paralysis. We describe our first 26 consecutive cases undergoing thyroplasty and arytenoid adduction with a standardized technique consisting of a combination of general anesthesia with tracheal intubation followed.
To determine whether variation in suture placement could improve the results of the arytenoid adduction procedure, a model was developed using fresh human cadaver larynges. Three-dimensional (3-D) motion of the arytenoid was determined by utilizing computed tomographic imaging with radiopaque markers on the apex and muscular and vocal processes.

10 Introduction to Videostroboscopy Katherine A. kendall Just like the beating of hummingbird wings, human vocal folds vibrate at a rate that is faster than can be perceived by the human eye. The evaluation of vocal fold anatomy, mucosal color, and gross movement can be performed while illuminating the vocal folds with a constant light….
Arytenoidectomy, or partial removal of the arytenoid cartilage, is performed to treat bilateral vocal fold paralysis. Persons breathe primarily through the posterior or back portion of the glottis. In fact, some refer to this area as the "respiratory glottis". In cases of bilateral vocal fold immobility or paralysis, the vocal folds do not open with breathing.
Options for surgical treatment of vocal cord paralysis include vocal cord injection, medialization thyroplasty, and arytenoid adduction. Each of these techniques results in medialization of the paralyzed vocal cord. However, arytenoid adduction is preferred in cases where there is a large posterior glottal gap or vertical misalignment between.
Arytenoid adduction (AA) is a framework surgery where the pull of the LCA muscle is recreated to achieve vocal fold repositioning. The physiologic effects of AA include the following: - Lowers the position of the vocal process - Medializes and stabilizes the vocal process - Lengthens the vocal fold - Rotates the arytenoid cartilage.
