 NASAL GLEET. 



CAUSES, SYMPTOMS AND TREATMENT TREPHINING STEPS 

 IN THE OPERATION AFTER TREATMENT. 



Nasal gleet is a sub-acute inflammation of the 

 membrane lining the frontal and maxillary sinuses of 

 the head. It may be due to various causes. The 

 only ones however, that we shall consider are 

 those that require surgical aid to induce partial or 

 complete recovery. 



CAUSES. 



Caries of the upper molars, the third, fourth, 

 fifth and sixth especially ; elongated inferior molar 

 teeth which wear the gums and alveolar processes of 

 the upper jaw, inducing caries; hypertrophy of th e 

 fangs of the upper molar teeth; exostoses on the 

 fangs ; external injury ; disease of the facial bones ; 

 collections of impissated pus; foreign substances 

 passing up through a cavity in a carious tooth's 

 cystic tumors; calcarious concretions in the maxillary 

 and frontal sinuses ; clots of blood in a state of de- 

 composition; straw, chaff, hay, etc., which accident- 

 ally pass from the nostril into the sinuses; or even 

 whole teeth passing up into the sinuses.
