An 8-year-old castrated male Boxer and a 10-year-old spayed female Yorkshire Terrier were evaluated because of dyspnea. In both dogs, the dyspnea persisted after elongated soft palate resection.
Laryngoscopic examination revealed caudal displacement of the epiglottis into the rima glottidis in both dogs. Excessive mobility of the epiglottis during respiration with episodic obstruction of the rima glottidis by the epiglottis was observed during fluoroscopic examination.
The epiglottis of both dogs was fixed in a horizontal plane by resection of a band of oral mucosa at the base of the epiglottis and closure of the mucosal defect with sutures. Fixation of the epiglottis resolved the dyspnea in both dogs.
Excessive mobility of the epiglottis can predispose to glottic obstruction and cause dyspnea in dogs. Fixation of the epiglottis in a horizontal plane may resolve dyspnea caused by epiglottic retroversion in dogs.
一只8岁去势雄性拳师犬和一只10岁绝育雌性约克夏梗因呼吸困难接受评估。两只犬在进行软腭延长切除术后呼吸困难仍持续存在。
喉镜检查显示两只犬的会厌均向声门裂尾侧移位。透视检查时观察到呼吸期间会厌过度活动，并伴有会厌间歇性阻塞声门裂。
通过切除会厌基部的一条口腔黏膜带并缝合黏膜缺损，将两只犬的会厌固定在水平面上。会厌固定术解决了两只犬的呼吸困难问题。
会厌过度活动可使犬易发生声门阻塞并导致呼吸困难。将会厌固定在水平面上可能解决犬因会厌后倾引起的呼吸困难。
