Outcome of two variations of a surgical technique performed for canine unilateral arytenoid lateralisation.

The purpose of this study is to compare the rate of aspiration pneumonia and survival time of dogs undergoing two unilateral arytenoid lateralisation (UAL) techniques. Eighty dogs diagnosed with laryngeal paralysis were treated by one of two UAL techniques: (1) a standard technique (ST) and (2) an anatomic preservation technique (APT). Outcome was assessed by in clinic re-examination and an owner follow-up questionnaire.
