Diseases of the Larynx

Bronchoscopic debulking of a feline tracheobronchial carcinoma and long-term outcome

“…3,10 The most common presenting complaints and clinical signs reported were respiratory difficulty (63%) and dysphonia (55.6%), the latter mainly seen when in the presence of laryngeal involvement as an extension from the proximal tracheal mass. 1,2,11 Jakubiak et al found that soft tissue opacities on cervical radiographs were significant indicators of neoplasia. 1 In previous reports of tracheal masses in dogs and cats, radiographic findings had no correlation with a specific tumour type.…”

Esophageal Dysfunction in Dogs with Idiopathic Laryngeal Paralysis: A Controlled Cohort Study

“…ILP has been characterized as a neurogenic atrophy of the laryngeal muscles because of progressive degeneration of the recurrent laryngeal nerves (RLNs) 1,30 . Both RLNs arise from their respective vagus nerves in the cranial half of the thorax and terminate as the caudal laryngeal nerves, providing motor innervation to all of the intrinsic laryngeal muscles except the cricothyroideus muscle, which is innervated by the external branch of the cranial laryngeal nerve 31…”

Ultrasonography of Laryngeal Masses in Six Cats and One Dog

“…Unfortunately, it cannot be used in cats because of the risk of development of obstructive laryngeal edema. 2 The indirect method of blood gas analysis pre-and postoperatively has been used in patients with laryngeal paralysis but is only useful for detection and follow-up study of laryngeal related hypoxia.…”
