[Extract] Laryngeal paralysis is characterised by a failure of one or both of the arytenoids to move during the respiratory cycle. Failure of abduction during inspiration causes an obstruction to airflow. The disease is usually a consequence of failure of innervation to the intrinsic laryngeal muscles, rather than primary muscle disease. The condition is commonly encountered in old Labrador Retrievers, Afghan Hounds and some other large breeds. Males are more frequently affected than females and most affected Labradors are older than 10 years. Laryngeal paralysis is usually considered to be a manifestation of a more generalised polyneuropathy. There is no compelling association with hypothyroidism.

Congenital laryngeal paralysis occurs in Bouvier des Flandres as an autosomal dominant trait. Trauma and neoplasia are rather less common causes, although thyroid carcinomas and cranial mediastinal tumours can certainly cause laryngeal paralysis.
