A review of equine laryngoplasty complications

Prosthetic laryngoplasty is a common treatment for equine recurrent laryngeal neuropathy (RLN). Complications of this surgery include immediate post operative problems, such as dysphagia, seroma formation, wound infection and sudden loss of arytenoid abduction. Longer term complications include gradual loss of arytenoid abduction, chronic coughing, arytenoid granulomas and dynamic upper airway collapse unrelated to RLN such as palatal dysfunction, and aryepiglottic fold or vocal fold collapse. However, the benefit of this procedure greatly outweighs these potential post operative complications, especially if appropriate surgical and post operative management practices are employed.
