Bourgeois describes certain complications of otic origin, characterized by intracranial hypertension and practically always accompanied by pupillary stasis. He pictures this condition as cerebromeningeal edema, due to an accumulation of cerebrospinal fluid, normal or altered, under pressure, and amenable to relief by therapeutic or surgical evacuation. He does not contend that a pathologic condition of the ear is the sole cause of this type of intracranial disorder but calls attention to other factors, such as concurrent infection, toxic irritation, traumatism and reflex excitation. However, he believes that this intracranial hypertension of otic origin is equally spectacular. Considering the condition from the point of view of an otologist, he maintains that the therapeutic and surgical attack in these complications of otic nature should be initiated from the vicinity of the ear. He describes three forms of this type of hydrocephalus: (1) superficial and diffuse edema of the meninges; (2)
