Forty dogs with clinical signs suggestive of upper respiratory tract disease underwent echolaryngography and laryngoscopy. Laryngoscopy was used as the definitive technique to diagnose laryngeal paralysis. The ultrasound investigation accurately indicated the presence of the paralysis and confirmed the uni- or bilateral nature of the disorder. Findings indicative of laryngeal paralysis included asymmetry or absence of motion of the cuneiform processes (30/30), abnormal arytenoid movement (16/30), paradoxical movement (9/30), caudal displacement of the larynx (2/30) and laryngeal collapse (1/30). Thirty dogs were found to be afflicted with laryngeal paralysis and ten had normal laryngeal motility.
40只出现上呼吸道疾病临床症状的犬接受了超声喉镜检查和喉镜检查。喉镜检查被用作诊断喉麻痹的确诊技术。超声检查准确地显示了麻痹的存在，并证实了该疾病的单侧或双侧性质。提示喉麻痹的表现包括楔状软骨运动不对称或无运动（30/30）、杓状软骨异常运动（16/30）、矛盾运动（9/30）、喉尾侧移位（2/30）和喉塌陷（1/30）。发现30只犬患有喉麻痹，10只犬的喉运动正常。
