VETERINARY SURGICAL OPERATIONS 



arranged in the form of a leaf are passed through the ear 

 so as to bind down the separated perichondrium against the 

 cartilage. The sutures are tied rather loosely to prevent 

 sloughing. (Fig. 221.) 



White's method consists of an incision of the whole sac

 edges. He further treats the parts beneath the edges with 

 tincture of iodine. Deformation of the concha from this 

 method is rare in dogs, but is frequent in cats.

AFTER-CARE.— The after-care consists of squeezing 

 out the fluid that accumulated amongst the sutures, pro- 

 tectfon of the ear against self-inflicted injury by the appli- 

 cation of a hood, and the removal of the sutures at the end 

 of eight to ten days. 



Ablation of Shoe-Boils. 



INDICATIONS.— The hygroma of the elbow whose 



walls have hypertrophied into a permanent neoplasm under 



■ the influence of constant injury, can be removed only by total 



ablation. So long as the walls are thin and the enlargement 



is constituted largely of a sac, lancing, antiseptic irrigations,
