Abstract

In dissecting the lacrimal sac for the purpose of dacryocystectomy or for effecting permanent drainage by one of the several well described methods, the surgeon usually experiences difficulties of two kinds: first, excessive bleeding which constantly obscures the operating field and, second, loss of anatomic orientation.

These difficulties are easily remedied by a slight modification of the operative technic, and operation on the lacrimal sac, which is frequently considered as technically rather difficult, becomes a simple and clean procedure.

IMPROVED TECHNIC

The one refinement of the technic consists in using a higher concentration of epinephrine in the procaine hydrochloride used for infiltration anesthesia. The usual surgical concentration of epinephrine is 1: 100,000 in 1 or 2 per cent procaine hydrochloride. By adding to this epinephrine-procaine hydrochloride mixture, obtained in ampules, 1 drop of sterile, but not boiled or autoclaved, solution of epinephrine (1: 1,000) for each cubic centimeter of
