524 DISEASES AND INJURIES OF THE FACIAL KEGION.

" If the practitioner suspects these structures to be in the 

 above condition, or that the sinuses contain such materials as 

 I have described, he will hesitate before he commences his 

 operation ; for if his experience corresponds with mine as to the 

 result in such cases, he will come to the conclusion that they 

 are incurable. For my own part, if I felt satisfied that the 

 pathology of the disease in any case that was presented to me 

 corresponded with the above description, I should certainly 

 decline to have anything to do with it in the way of treatment ; 

 but as it is difficult to diagnose such cases with any degree of 

 certainty, a prognosis is worth but little. Our investigations, 

 therefore, should be extended beyond a mere surface examina-

 have partly accomplished the operation for the cure thereof; or 

 if, on the contrary, he considers the affection to be incurable, he 

 will be prepared to advise that the patient be disposed of or 

 destroyed, as may be deemed best. 



" Disease of the sinuses is sometimes compHcated with one of 

 a similar character of the nasal passages ; indeed, it will be an 

 extension of the affection from one part to the other, or it may 

 have commenced simultaneously in both cavities. 



" The symptoms indicative of the nasal passage as well as the 

 sinuses being affected are as follows : — The discharge, which is 

 never very copious, is nevertheless continuous ; the breathing is 

 embarrassed, particularly if the opposite nostril is closed, when 

 a considerable impediment will often be evinced, and percussion 

 gives a dull sound over the whole of the side of the face.
