CHRONIC NASAL GLEET PRODUCED BY A 
DISEASED TOOTH. OPERATION. CURE. 
By J. Horsbuugh, M.R.C.V.S., Dalkeith. 
About twelve months ago I was consulted by Mr. 
Herdman, farmer, Southside, respecting a mare, which had 
a considerable discharge from the near nostril. The account 
he gave me was, that she had been under treatment by Mr. 
G. Houston, V.S., Preston, for about eighteen months, and 
that he had often taken her to what he called head-quarters, 
viz., Professor Dick’s, where the superior maxillary sinus had 
been opened with the trephine, something like a year since. 
The discharge, however, continued to flow, both from the 
nostril and wound. 
On examination, I found that the defluxion had an offensive 
smell, and that the submaxillary gland was considerably en- 
larged, causing some suspicion of the existence of glanders. 
The opening into the sinus had apparently been made a little 
too high up, so that the central instead of the inferior part 
of the sinus was perforated. I proposed at once to open it 
lower down, but as my examination w 7 as made in the public 
street, on the market day, I thought it better to see the mare 
again, at her owner’s residence, before fully deciding as to what 
was best to be done. On examining her at home, I found that 
the whole mischief was occasioned by a diseased tooth, and 
which, strange to say, had not been detected in the previous 
examinations. With the assistance of a smith I removed the 
tooth, which was split up its middle, and considerably decayed. 
It was more than two inches long, and w r as bent outwards 
towards the cheek. The odour emitted from the part was 
most offensive. I also opened the frontal and maxillary 
sinuses, both of which were filled with fetid pus. The 
wounds were first treated with a weak solution of chloride of 
lime, and subsequently with an ordinary astringent lotion. 
In addition to the local treatment, 1 administered the din- 
iodide of copper. 
After a considerable time the wounds were allowed to heal, 
and the mare appeared much better; but very shortly the 
discharge began again to flow from the nose worse than ever, 
the smell also was almost intolerable. Determined, if possible, 
to make a cure of the case, I cut into the sinus again with a 
skull saw, taking out a triangular piece of bone, about two 
inches long by one inch and a half broad. At the upper 
part of the cavity I found some masticated food in a state of
