Such subsequent hyperemias are not now as common as when the injections were at first attempted, and the author may say freely that they never occur when the proper method and material is used.

Paget says: “In a few cases—but only in a few—some reddening of the skin has followed the injection, and in a few this has been very slow to fade.

“The few referred to are of a record of twenty-two nasal cases, but no data is given whether the operator used paraffin of high or low melting points. F. Connell found that redness in that case continued for a year, diminishing very little in that time. It appeared on the second time after the operation for a correction of a saddle nose, and remained stationary for about one month. Twenty drops of paraffin were injected. It very gradually increased, so gradually, in fact, that there is still a distinct reddened area over the bridge of the nose. On pressure this redness will disappear, but returns immediately after the removal of the pressure. A few dilated and tortuous capillaries course their way over the area. The condition is still present fourteen months after the injection.

“There has been practically no change or decrease in the redness during the last six or seven months, it is not as marked as it was during the first few months, but still requires the profuse application of face powder in order to prevent her nose from being conspicuously red.”

The above case has been cited because it is typical of such condition, and while the amount as stated was quite small, one is almost nonplussed for an explanation of the result, yet it undoubtedly must have been due to a close attachment of the skin to the underlying structures, necessitating pressure, which is known to cause it.

However, it is possible to have such redness develop weeks or months after the injections are made. In such cases it is not due to the primary pressure of the injection, but to that of the newly developed tissue which has taken its place, but which is slightly overdeveloped for the same unaccountable reason already referred to.

Almost every surgeon who has used this method of restoring the contour of parts of the face has observed redness, more or less permanent, follow the method used, but in most cases liquid paraffin of high melting points had been forced into the tissues at great pressure.

In one case, that of a southern operator, the entire tip of the nose had become injected by primary diffusion or direct filling.

It became inflamed immediately after, and some weeks later, when the swelling had subsided, the lobule was found to be very hard, tense, and extremely red. Two years after the author saw this case, and the tip of the nose still appeared like a red cherry with numerous capillaries showing over its area, while the rest of the nose, although much broadened by secondary displacement of the paraffin, was natural in color.

This proves that as the pressure was relieved by absorption and displacement, the tissue took on a normal appearance, whereas in the lobule of the nose, where there was no relief from the pressure, nature could do nothing to relieve the inevitable result.
