38 Catarrh of the Guttural Pouch. 



the enlarg-ement of the guttural pouch is already quite consid- 

 erable, and if the sac has become adherent to neighboring 

 structures, the prognosis as to recovery is very bad. Irrigation 

 of the guttural pouch with a Guenther ( 

 on account of the danger of aspiration.

Bloating: of the Guttural Pouch. ( Tympanitis s. meteorismus sacci 

 aerophori.) Bloating of the guttural pouch (meteorismus idiopathicus) 

 is sometimes seen in foals as a primar.y affection. The cause of it is 

 probably paralysis of the muscles of the Eustachian tube, in consequence 

 of which active dilatation ceases, which causes the expulsion of air (Ger- 

 lach, Dieckerhoff, Peter). Exceptionally bloating of the guttural pouch 

 may be due to congenital anomalies (the presence of folds of mucosa 

 which close like valves [Niebuhr, Thomassen]). The affection occurs 

 secondarily in conseciuence of chronic catarrh of the guttural pouch 

 (meteorismus symptomaticus) . 



The symptoms are a puffy, elastic swelling in the region of the 

 parotid (Fig. 4) which may be unilateral or bilateral; on percussion 

 a tympanitic sound is elicited ; the swelling may decrease upon pressure 

 Slid a peculiar noise may then become audible. Cases are also observed 

 in which the swelling is only found in the pharynx. Difficulty in 

 re^iration is always observed, difficulty in deglutition occasionally. 

 In very serious cases pressure upon the bloated guttural pouch produces 

 whistling or roaring sound during respiration. Nasal discharge or 

 swelling of lymphatics are absent in idiopathic bloating of the guttural 

 pouch. 



The treatment consists in opening the guttural pouch, if necessary 

 also in artificial dilatation of the tubal opening, and irrigation.
