CANINE AND FELINE SURGERY. 



OPERATIONS ON THE EAR. 



Examination of the Interior before, and Application of 

 Dressings after, an Operation. — A cursory examination of 

 the interior of the ear can be made with the fingers, but 

 a speculum of some pattern or other is always an advantage, 

 as by its aid dressings can be much more easily applied 

 and any irritant matter more easily removed. There are 

 several patterns which are convenient for canine work, the two 

 most useful being Kramer's and Avery's.

Dressings may be applied on wadding by the aid of a slender 

 pair of forceps or on the end of a fine probe ; for fluids a syringe 

 with a curved and protected nozzle has been devised or an ear 

 sponge can be used, whilst for powders after the cavity has been 

 rendered thoroughly dry an insufflator is very useful. 



Whatever method is adopted, dressings for the interior should 

 always be applied as gently as possible, because, especially 

 when wounded or irritated, it is extremely sensitive. 



Removal of Polypi, Tumours, or Enlarged Ceruminous 

 Glands. — Abnormal growths in this region are best removed 

 by ligature if they are so situated that one can be success- 

 fully applied. In other cases the scalpel must be resorted
