Symptoms: Swelling, dyspnoea and dysphagia from pressure; 

 Lead extended; slight fever. 



Treatment: Open through Viborg's triangle as described in pre- 

 ceding answer. In case of subparotid abscess, use a blunt instru- 

 ment or finger to burrow through the parotid gland. Some operators 

 prefer to make the incision on the median line and dissect through 

 to the abscess along the lateral wall of the larynx. In all cases, 

 good drainage and thorough disinfection are necessary. Use trache- 

 otomy tube to avoid suffocation which may follow the excitement 

 caused by operating. 



Give the treatment of pharyngeal polypi. 



Adjust the mouth speculum and attempt grasping and removing 

 the polypi with the hand introduced through the mouth. If this 

 method fails, perform laryngectomy, pass hand or ecraseur through 

 the larynx into the pharynx and remove the growth, preferably 

 by torsion. If this fails, cut the growth away with scissors or 

 scalpel. 



Give the treatment for choking. 



Four methods may be employed. 



1. Return the foreign body into the pharynx by manipulations 

 over the oesophageal furrow and with the hand in the pharynx, 

 or with extracting instrimients ; emetics such as apomorphine and 

 veratrine may assist. 



2. Reduce the size of the foreign body in situ (soft objects may 

 be crushed by hand). 



3. Force the foreign body onward into the stomach with the 

 probang. Great caution should be observed in case of sharp objects 

 as bones, etc. Likewise, a mass of oats may be more firmly impacted. 



4. CEsophagotomy. This can only be performed on the cervical 

 portion of the oesophagus and is only practised when the other 

 methods fail. 



Unless symptoms are alarming, it is best to avoid all treatment 

 in case of impaction of oats, as such cases often remedy themselves 

 in the course of a few days. In all cases, withhold food and water 

 until the condition is relieved to avoid the danger of inhalation 

 pneumonia. 



Describe oesophagotomy. 



The animal can be operated upon in the standing or recumbent 

 position. The point of operation is usually determined by the 

 location of the foreign body which necessitates the operation. Shave 

 and disinfect the skin. Make an incision 10 cm. long through the
