 peroxid, which loosens up the deposit, and then 

 removing the wax with forceps, swabs, or an ear 

 curette. Ulcers should be first curetted and then 

 touched up with a stick of nitrate of silver. Polypi 

 are to be ablated either by excision with scissors 

 and scalpel or by the use of a small wire ecraseur 

 or snare.
