Fig. 520.—Author’s Electric Apparatus for Tattooing Scars.
In using the electric apparatus the needle ends are dipped into the pigment paste, to which a little glycerin is added to bind it, and this is tattooed or pricked into the scar.
If, after the parts are healed, the color is too light, the scar may again be gone over until the tint matches somewhat the tint of the skin. Other pigments may be used, according to the complexion of the patient.
Some scars, the resultant of negligent coaptation, are to be excised according to the Celsus method and are brought together with a number of fine silk sutures.
If the skin is found to be attached too closely to the subcutaneous structure, it must be dissected up to render it mobile.
When the scar cannot be removed by excision the hypodermic use of thiosinamin may be tried.
Thiosinamin or rhodallin is only slightly soluble in water, but the addition of antipyrin according to Michel renders it useful for hypodermic use. The formula preferred by the author is made as follows:
| ℞ | Thiosinamin | grs. ij |
| Antipyrin | grs. j | |
| Aqua dest. | gtts. xx. |
