The mass injected is at once molded down flat with the thumb or forefinger.

A number of such injections may be made at both sides at the one sitting. The ethyl-chlorid spray may be employed to render the parts less painful. At no time should the entire shoulders be filled at one sitting, for fear that the reaction may be severe or that for any unforeseen cause infection results which would in such instance be indeed difficult of treatment, eventually leaving the parts scarred and unsightly.

Nor should the mass be injected intracutaneously, a fault sometimes observed about the base line of the neck anteriorly and laterally where the operator has been timid in avoiding the exterior and anterior jugular veins. Such injections invariably result in abscess, or when not extensive enough to cause necrosis the skin assumes a more or less permanent red or yellow discoloration over the site so injected.

The treatment for the partial or total removal of such spots has been referred to.

In the average case of contour restoration of the shoulders about eight sittings are required, two sittings being given each week, and as many injections made as is deemed necessary or advisable at each.

All the precautions of technic heretofore given should be employed. The reaction following such injections is never severe, and little or no treatment is necessary.

The needle openings are covered with aristol collodion or the isinglass adhesive plaster.

At the end of six months or more after the injected matter has been quite thoroughly replaced with new connective tissue it is often found necessary to inject small quantities here and there about the shoulders, owing to the contraction of the new tissue and its ultimate fixed disposition about the parts more than to the absorption of the mass injected.

Furthermore, a certain amount of edema or swelling follows the injection of any foreign matter under the skin which is not, in cases of this kind, so readily absorbed, giving during that period of time a more pronounced contour or fullness, which, passing away in the natural course of events, does not imply the absorption of the matter injected—a statement so often made by those not in favor of using paraffins of low melting points for subcutaneous protheses.

Such result, however extensive, as it might be in some cases for the lack of proper injection or in the case with oil injections is at all times correctable, while the hyperplastic knobs, so often following the injection of paraffins of high melting points about the shoulder, can only be removed by surgical means, which leave the parts more unsightly than before anything had been done for the patient.
