側頭骨標本における内側型高位頚静脈球の観察

Recently the cause and effect relationship between medial high jugular bulb and inner ear disease, such as sensorineural hearing disturbance or Meniere's disease, has been reported in some articles. It was supposed that inner ear disease was caused by stenosis of internal auditory canal or endolymphatic duct obstruction. We studied temporal bone findings of medial high jugular bulb in 293 temporal bones. The result was as follows:
1) Medial high jugular bulb seems to have no effect on internal auditory canal.
2) There are some possibilities that medial high jugular bulb has an effect on development of periaqueductal pneumatization and of endolymphatic duct and endolymphatic sac.
