In 1929 I reported 154 cases of otitic sinus thrombosis with a mortality rate of 22 per cent. Among these cases were 22 in which the classic symptoms of sinus thrombosis were not manifested until after the performance of the mastoid operation. An exhaustive study of these 22 cases revealed that they included two well defined types of sinus thrombosis, namely, latent and postoperative.1 Since the time of that communication I have observed other cases of latent and of postoperative sinus thrombosis which in general confirmed the description given in the original paper. I believe that the distinction between the two types of sinus thrombosis is of such clinical importance that I should take the opportunity to present 2 cases recently observed at the Research and Educational Hospital of the University of Illinois, which afford excellent examples of the two clinical types of the condition.
