In Vitro Model for Testing Novel Implants for Equine Laryngoplasty

Abstract

This model will allow testing of multiple novel techniques and may facilitate development of improved techniques for prosthetic laryngoplasty.

Long‐Term Maintenance of Arytenoid Cartilage Abduction and Stability During Exercise After Laryngoplasty in 33 Horses

“…Perilaryngeal adhesions and fibrosis of the cricoarytenoid joint occur to varying degrees after LP and surgical arthrodesis of the cricoarytenoid joint is performed by some surgeons, which may prevent loss of ACA. Adhesion formation may explain why most abductory loss we observed occurred in the first 6 weeks.…”

In VitroMechanical Testing of Braided Polyurethane Elastic Fiber and Braided Polyester for Equine Laryngoplasty

“…These include stainless steel wire, cables, washers, nylon, polyethylene, and braided polyester . Braided polyester is currently the most commonly used material for equine laryngoplasty . A recent in vitro study compared 3 materials and identified the braided polyester, Ethibond™ (5 USP or 7 metric, Ethibond Excel™, Ethicon, Inc., Somerville, NJ) to be the most appropriate material for laryngoplasty; however, none of the materials were elastic (2 Ethilon® and 5 Fiberwire®) …”

Ex Vivo Mechanical Evaluation of a Sternal ZipFix®Implant for Prosthetic Laryngoplasty in Horses

“…This could be overcome with incorporation of stepwise cyclic loading suggested by Willsallen et al in an attempt to incorporate the benefits of applying cyclic load and reach failure points obtained during single load to failure. Alternatively, ex vivo inspiratory pressure models could be used for evaluation of alternative materials for prosthetic laryngoplasty …”
