CATARRH OF THE GUTTURAL POUCHES 27 



CATARRH OF THE MAXILLARY AND FRONTAL 

 SINUSES. 



Definition. — ^A collection of mucopurulent exudate in the 

 sinuses of the head. / 



Occurrence. — Commonest in the horse, but is seen in the 

 ox. In cattle the frontal sinuses are usually involved. 



Etiology. — Most frequently due to diseases of the teeth 

 (caries dentium; alveolar periostitis). In cattle it may 

 follow dehorning. Certain infectious diseases such as 

 glanders, malignant head catarrh, etc., may induce it. 



Symptoms. — Nasal discharge which is often unilateral. It 

 may be intermittent, copious or limited, and sometimes 

 fetid. In some cases the bone covering the sinuses is atro- 

 phied and bulged outward, distorting the face. There may 

 be conjunctivitis and partial occlusion of the nasolacrimal 

 duct. Swelling of submaxillary lymph gland of the affected 

 side is usually noted. 



Diagnosis. — ^With a drill or gimlet bore into the suspected 

 sinus. 



Treatment. — Surgical. 



CATARRH OF THE GUTTURAL POUCHES. 



Definition. — An accumulation of exudate in the guttural 

 pouches. In some cases the pouch is filled with solid, cheesy 

 bodies, each of about the size of a bean (dried pus). Disten- 

 tion of the pouch with gas may result from a decomposition 

 of the exudate. 



Catarrh of the guttural pouches is rare. It is mamly of 

 surgical interest. 



Etiology. — ^Rarely foreign bodies; spread of inflammation 

 from neighboring organs; infection (glanders). 



Symptoms. — Similar to those of chronic nasal catarrh. 

 Swallowing and breathing may be interfered with. The dis- 

 charge is usually unilateral, mucopurulent, fetid, and increases 

 when the head is lowered. In typical cases the parotid 

 region is swollen and if pressed upon the discharge is tem- 

 porarily increased, dyspnea induced and a roaring sound
