Fig. 290.—Author’s All-Metal Drop Syringe.
Since there were no objections to making the barrel large enough to permit of injections, such as are required for restoring the contour of the cheek and the neck and shoulder, it was made to contain 10 c.c. working capacity, overcoming the necessity of constant refilling, when comparatively large injections had to be made—a fact worth remembering from a practical standpoint, although two or three of these syringes, specially prepared for each patient, might be found desirable by some operators. Yet the simplicity and ready facility with which this instrument can be used and refilled renders it useful and sufficient for performing operations of this nature to any judicious extent.
Syringes holding small quantities of the paraffin mixture are found to be a nuisance.
The following operators employ syringes of the capacity given:
| Brœckært | 3 c.c. | 50 mm. |
| Eckstein | 5 c.c. | 80 mm. |
| Freeman | 5.6 c.c. | 90 mm. |
| Downie | 10 c.c. | 150 mm. |
The instrument employed by Brœckært, holding less than one dram, would be of little use except to correct very slight deformities about the brow or nose, or dressing up or completing the contour of parts previously filled by larger injections.
Another syringe similar in type to the author’s, but of a capacity of 5.6 c.c., was introduced by Harmon Smith.
The principles of the syringe are alike, but the style of handles, two flat metal bars at opposite sides, offers no objection when comparatively hard mixtures of paraffin and vaselin are used.
