Abstract

Five adult performance horses presented with the complaints of exercise intolerance and/or upper airway noise. Endoscopy revealed reduced arytenoid movement, mucosal defects with protruding granulation masses and occasional perilaryngeal swelling. While standing, a 1-cm stab incision was created, and a 5-mm trocar with sleeve was inserted through the cricothyroid membrane using nasopharyngeal endoscopic guidance. A fiber guide containing a 600-micron diode free-beam laser fiber was inserted, and the masses were ablated to the cartilage surface. Lesions determined to be limited to the cartilage substance were further ablated using the laser. Lesions determined to extend through the cartilage were manually debrided using an angled curette. The wounds were left unsutured after placing 2-3 ml of antiseptic ointment subcutaneously. Reexamination revealed resolution of the lesions in all horses, and arytenoid mobility was present. Lesions affecting the corniculate process (two) resulted in noticeable atrophy. The author concludes that laser-assisted debridement of septic tracts in the arytenoid cartilages that have not become completely deformed by the process is a reasonable procedure to restore athletic function.
