PARALYSIS OF THE PHARYNX. 



From nervous bulbar lesion, or toxic from the pathogenic bacteria. 

 Transient or permanent and fatal. vSymptoms : dysphagia: liquids expelled 

 by nose or enter lungs. Inhalation pneumonia. Facial palsy. Roaring, 

 laryngeal thrill. Atrophy. Gangrene. Treatment : remove cause : com- 

 bat bulbar hypersemia and cephalic congestion : cold : derivatives, elec- 

 tricity : blisters : antiseptics. 



Thi.s has been described as a rare affection, yet it is often a 

 marked symptom of cerebro spinal meningitis, and has been 

 observed in infections pneumonia, and influenza of the horse 

 (Cadeac, Palat) as well as in rabies, and traumatic injuries of the 

 brain. 



The existence of the condition usuall}' implies disease of the 

 bulb at the roots of the vagus and glossopharyngeal nerves, or 

 swellings affecting these nerves or the sympathetic along its 

 course. The morbid condition may be transient in which case a 

 speedy recovery may follow, or it may be permanent and end 

 fatally. 



Symptoms. Swallowing is impossible and the animal refuses 

 food and drink or if the latter is forced on him it is rejected by 

 the nose or mouth when the head is lowered or still worse, it 

 enters the larynx and descends into the lungs. The larynx in- 

 nervated by the same trunks is usually involved and the ali- 

 mentary solids and liquids determine gangrenous bronchitis and 

 pnetimonia. with labored breathing, foetid breath and violent 

 dyspnoea. In other cases the facial nerve is involved, the nos- 

 trils and lips are flaccid on one or both sides, and the eyelids and 

 ears may droop. There may be snuffling breathing from the 

 closure of the alae nasi, or roaring from the approximation of 

 the arytenoids and vocal cords. If the affection is unilateral the 

 difficulty of breathing is greatly diminished and even deglutition 

 may be effected with some effort. There is usually, however, 

 the obvious unilateral paralysis of the face, and especially of the 

 larynx, with the distinct thrill, during inspiration, conveyed to 

 the finger placed on the larynx. 



Complications in the form of grangrene and atrophy of parts
