Unilateral partial arytenoidectomy was performed in 22 horses. Six horses had arytenoid chondritis, 14 horses had idiopathic laryngeal hemiplegia (11 of which had been treated unsuccessfully by insertion of a laryngeal abductor muscle prosthesis), and two horses had laryngeal hemiplegia resulting from perivascular injection of an irritant drug. After surgery, eight horses (36%) developed a nasal discharge of food and/or water that was of clinical significance in only two of them. The operation resulted in marked improvement in exercise tolerance in all 20 horses tested, although two could not work because of severe exercise‐associated coughing. Mild inspiratory stertor was present in eight horses and was excessive in one. It was concluded that the high incidence of problems related to swallowing rendered the method unacceptable. Modification of partial arytenoidectomy by silicon augmentation produced improvement in one horse.
