Fístula. n.s. [Latin; fistule, French.]
- A sinuous ulcer callous within; any sinuous ulcer.
That fistula which is recent is the easiest of cure: those of a long continuance are accompanied with ulcerations of the gland and caries in the bone. Wiseman's Surgery.
- Fistula Lachrimalis. A disorder of the canals leading from the eye to the nose, which obstructs the natural progress of the tears, and makes them trickle down the cheek; but this is only the first and mildest stage of the disease: in the next there is matter discharged with the tears from the pinicta lachrimalia, and sometimes from an orifice broke through the skin between the nose and angle of the eye. The last and worst degree of it is when the matter of the eye, by its long continuance, has not only corroded the neighbouring soft parts, but also affected the subjacent bone. Sharp's Surgery.
