TREATMENT. 



The treatment consists in removing the frag- 

 ments of teeth. This may be accomplished in va- 

 rious ways, either the forceps, elevator, or trephine 

 and punch may be used, whichever best answers 

 the purpose. If the tooth is carious and an upper 

 molar, accompanied by a discharge from the nos- 

 tril, it is best to use the trephine, even after the 

 remaining portion has been removed. That portion 

 which is absent may have passed up into the sinus, 

 and unless removed will keep up a continual irrita- 

 tion, attended by a constant discharge (of a very fetid 

 character), from the nostrils. Whole teeth occasion- 

 ally pass into the sinus and produce serious results. 

 I have never seen a case where a fragment of tooth 

 had passed into the sinus but have taken whole teeth 

 from those cavities. The after treatment will con- 

 sist in keeping the parts clean and if trephining has 

 been resorted to, the opening should receive proper 

 attention. 



During the summer of 1888 a large brown mare 

 was brought to Dr. B. C. Thomas, D. V. S., of 

 Chicago, which had been discharging from the 

 right nostril for some time. The walls of the sinus 

 were very much bulged. On examination he found 

 the fourth upper, molar split and the inside half gone. 

 He easily extracted the other half and by exploring 

 the cavity with the finger found it to be full of feed.
