Various and noted surgeons point out that these subcutaneous injections should be made under general anesthesia, i. e., ether, while others consider the hypodermic use of cocaine or Eucain β solution in one to four per cent necessary to accomplish good results.

The author considers the method in the first case objectionable both as to patient and operator, entailing much discomfort to the one operated on and demanding an unnecessary waste of time for the etherizing and recovery. Likewise is the employment of a local anesthetic not indicated or demanded, since the operation to be undertaken necessitates only the pain associated with the prick of the needle through the skin.

The objection to etherization is obvious, while the hypodermic employment of any local anesthetic, by the very fact of its presence of volume and its physiological action upon the tissue, tends to interfere with the proper injection of the parts by reason of temporary swelling of the parts, not caused by the later injections of the prothetic mass.

If in nervous irritable patients an anesthetic is required to allay fear it is best to use the ethyl-chlorid spray upon the skin sufficiently to overcome the sharp sting of the needle insertion. For this purpose the ether spray is used only to the point of blanching the skin, and no longer.

This mode of procedure is especially useful when a number of injections are to be made, as in the rounding out of a cheek or of the shoulders, in which the contour cannot be restored from one point of injection, as will hereinafter be described.

The patient, being now in readiness, the skin over the area is lifted or pinched up with the fingers of the left hand of the operator as a guide to its mobility and to steady the part.

The point of the needle is now forced through the skin and into the subcutaneous tissue at a point along the periphery of the deformity and pushed a little beyond the center of the cavity to be filled.

The elevation of the skin is in the meantime partly kept up with the needle itself, while the syringe is grasped with the freed hand, the thumb and forefinger of the right hand being placed upon the handle of the screw or piston rod, which they must rotate to force the semisolid mass from the instrument.

Before beginning the injection an assistant is instructed to press with his fingers the tissue about the margin of the defect to prevent the filling from becoming misplaced or being forced into undesirable channels, especially if the skin over the defect is found to be thick and inelastic.
