THE TUMORS OF THE SINUSES.

sixteen-year old mare, discharges abundantly, has a small gland, 
and an abnormal bulging of the right side of the face. A vet¬ 
erinarian believes the animal has glanders. Lflautard disagrees 
and diagnoses a simple collection of the sinuses. The teeth 
were normal; there was no lesion of the buccal mucous mem¬ 
brane^ The inferior maxillary sinus is trephined, and three 
dental cysts are found, each containing a hard, movable body, of 
the consistency of enamel; a rudimentary tooth, similar to those 
met in the cysts of the temporal region. The extraction of the 
teeth and the ablation of the cysts were followed by a rapid re¬ 
covery. 
Though our records are poor in observations relating to cysts 
of the sinuses, it is certain that numerous practitioners have 
seen them, have employed the modes of treatment we have just 
mentioned and cured their patients. 
This first group includes lesions which remain limited to the 
sinuses and are manifested only by the symptoms of the sup¬ 
purative inflammation of these cavities, which at a later period 
comes to complicate the fact of their presence. 
Myxomas and fibrous polypi form two other varieties of 
tumors of the sinuses which are not much more serious than the 
preceding, when they are recent and limited to one of these 
diverticulums only. Fibrous polypi, however, are in general 
more serious than myxomas. 
Both start ordinarily from the ethmoid or the floor of the 
sinuses ; they grow rapidly, press against the bony plates, prin¬ 
cipally the external, spread to the corresponding nasal cavity, 
and may assume there large dimensions ; give rise to special 
symptoms, interfere with respiration, produce a nasal roaring , 
and even bring on death by asphyxia. 
Trasbot has published a curious case of this nature. A mare, 
of Mecklenburg breed, had an intermittent running on the left 
side of six months’ standing. This discharge is muco-purulent, 
striated with blood at times. A tumor of the sinuses is sus¬ 
pected. The running at the nose increases, the maxillary gang¬ 
lions are swollen, the animal roars loudly when at work.
