The reaction is never severe, and is easily controlled by cold applications. If, after one week, there is shown a tendency to sagging of the mass, it should be gently massaged upward with the finger several times during the day for at least two weeks; this will keep it in place, and allow nature to replace it with new connective tissue when desired. DEFORMITIES ABOUT THE CHEEKS =Deficiency of Cheek= _(Total and Partial)_.—A total lack of proper contour of the cheek, generally termed flattening, may be due to hereditary causes, but is generally dependent upon a cachexia due to a general disease, or fatty degeneration of the muscular structure of the cheeks, as found in those beyond middle age. A partial deficiency of the cheek or cheeks is usually hereditary, but may be dependent upon digestive disorders or other causes of malnutrition. This class of deformity is found more often in women than men. It is usually bilateral. Unilateral cheek deficiency, whether partial or total, may be congenital, but is often the result of a local paralysis causing hemiatrophy. Traumatisms early in life or during birth and amputation of the inferior maxillary are other causes. This class of deformity is quite readily corrected by subcutaneous injection; in fact, it is the only known method of merit, superseding the former resort to partial correction by massage or artificial and temporary correction by the wearing of plumpers in the buccal cavity. The method of procedure is the same in all cases, the number of injections and quantity varying, of course, with the extent of the defect. As with the rebuilding of the contour of the lips so with the cheeks, which must of necessity be mobile and flexible, the injection of hard paraffin is out of the question. The author has observed a number of such cases, and is free to say that in each case the result was not only abnormal in appearance, but a source of great annoyance to the patient. What is worse is that the paraffin once injected can never be removed except in places where an actual encystment has taken place, in which case the hard mass may be removed through a small incision made directly over the mass and introducing a grooved director into the opening then by the rotation, or to-and-fro movement of which, combined with digital pressure, the cyst is evacuated. Once the mass is replaced by a network of connective tissue it could not be removed except by an extensive dissection and extirpation, which leaves behind it cicatrices far worse than the appearance of the parts before operation. The author injects cold sterile white vaselin below the skin here and there about the cheek at the sites of deepest deficiency. These injections may be made under ethyl-chlorid anesthesia. Each injection is carried to the extent of causing a lump below the skin, the quantity being judged from a thorough experience with similar cases.
