A rather large syringe with a screw nut togradually force down the piston is very convenient.

Local anaesthesia by infiltrationis liable to conceal the deformity and deceive the water may be injected to correct the deformity and thusbecome a guide to the quantity of paraffin needed to obtain thecorrect contour. A few hours later, after the water has beenabsorbed, an equal bulk of paraffin can be injected. The punc-tures, if made with aseptic precautions, need no dressing. The.

In a fewdays the redness and feeling of pressure subside. It is much better to introduce too little paraffin than to run therisk of depositing too large a mass. It is easy to repeat theprocedure in a few days or weeks, if after the lapse of that timethe inadequacy of the operation is evident.
