Anterior Superior Third Nasal Deficiency and Correction Thereof.
The needle should be introduced laterally and anterior to the angular vessels to prevent their occlusion and injection. The point of selection is made at about the middle of the deformity. The needle is introduced until its point lies in the center of the depression, or at the median line from the anterior view.
The mass is injected slowly as the skin of the nose is pinched up between the forefinger and thumb of an assistant.
The part is injected until a tumefaction, equal in body to the extent of the deformity, is attained.
The needle is allowed to remain in place for a moment, to permit of a stoppage of the threadlike mass, usually following the pressure applied to the piston, after the operator has stopped turning the screw. This will prevent the mass from following into the channel made by the needle, or the backing up of the mass, as it were. Should this occur the paraffin mixture should be squeezed from the skin opening to prevent the formation of an intercutaneous encystment.
Immediately the needle is withdrawn the operator places a finger tip over the opening and proceeds with the thumb and forefinger of the right hand to mold the mass into the desired shape.
The post-operative treatment should be as previously given, and is the same with all injections about the nose, so that it will not be referred to again under this heading.
