Endoscopic Arytenoid Lateropexy for Isolated Posterior Glottic Stenosis

Abstract

After proper mobilization, endoscopic arytenoid lateropexy can be considered as a minimally invasive function-preserving procedure even for severe PGS. This treatment option provides stable improvements in breathing ability and good voice quality without the need for tracheostomy.

A comparison between transoral glottis‐widening techniques for bilateral vocal fold immobility

“…B). Modified vocal cord laterofixation (VCL‐suture 2), in which a second suture was inserted anteriorly from the original position (Fig. C). Endoscopic arytenoid abduction lateropexy (EAAL) . The arytenoid cartilage was rocked into its abducted position, and then a suture loop was placed round the vocal process (Fig.…”

Comparison of endoscopic techniques designed for posterior glottic stenosis—A cadaver morphometric study

“…However, by open techniques these results could be improved to 100%, but tracheostomy might have to be sustained for weeks, and many of these patients had to face a significant deterioration of laryngeal function and voice. By contrast, in our earlier studies we presented a consecutive series of 42 patients with different grades of stenosis. All were treated successfully by a minimally invasive endoscopic method following the resection of fixating scar, and mobilization of the cricoarytenoid joints and a temporary endoscopic bilateral arytenoid lateropexy.…”

“…The purpose of our method is to provide the largest possible space in the posterior commissure, thus keeping the wounds apart until healing, diminishing the chance of developing a fibrin cicatrix. Moreover, the durable separation of the opposing wound surfaces over a period of weeks counters the contraction forces of the scarring process due to the myofibroblasts in early healing …”

Lysis of interarytenoid synechia (Type I posterior glottic stenosis): Vocal fold mobility and airway results

“…A review of the literature yields several studies1, 3, 9, 12 of posterior glottic stenosis that include PGS‐I and also descriptive case reports13–16 (Table II). Of these 10 cases, 7 had a tracheostomy and all patients developed an improved airway postoperatively, with most reporting normal voice.…”
