クモ膜下出血症例における側頭骨病理所見

抄録

We studied temporal bone histopathology in cases diagnosed as subarchnoidhemorrhage clinically or histopathologically. And we examined the quantity of blood in the internal auditory canal, the route of blood into cochlea, the width of cochlea aquaduct and the condition of inner ear. The cases in which blood entered from cochlea aquaduct to scala tympani were more than all the cases in which blood entered from internal auditory canal to modiolus. Therefore, it seemed that the blood in subarchnoid space tended to enter from cochlea aquaduct rather than internal auditory canal whenever blood in the internal auditory canal is a lot or not.
