Endoscopic diagnosis and surgical resolution of one-sided laryngeal paralysis and secondary laryngeal collapse in dog.: Case report

A twelve and a half year old, male staffordshire terrier dog is presented by the authors, which was admitted to the clinic with a few-week-long history of exercise intolerance, coughing, gagging and severe post-exercise dyspnea. The radiographic evaluation of the larynx (Figure 1) and the thorax (Figure 2) as well as the thorough endoscopic examination of the upper airways (Figure 3 and 4) confirmed the diagnosis of laryngeal paralysis combined with laryngeal collapse. After the stabilisation of the patient's respiratory status, a successful left sided cricoarytenoid lateralisation was performed (Figure 5 and 6). The case report is the first of its kind in the Hungarian veterinary literature, concerning the description of conservative and surgical treatment of laryngeal paralysis combined with laryngeal collapse. The authors summerise the incidence, the etiology, the clinical symptoms, the diagnostic tools and the possible surgical resolutions of the laryngeal paralysis and laryngeal collapse with special emphasis on the cricoarytenoid lateralisation.
