To provide anatomical basis for operation of internal auditory meatus(IAM). Correlation structures with IAM were measured according to sign of hiatus of facial nerve.
These structures include spinous foramen, superficial geater petrosal nerve, superficial lesser petrosal nerve, hiatus of facial nerve were measured on 24 wet cranial bone (48 sides).
It is demonstrated that 8.3% geniculate ganglion and labyrinth segment of facial nerve Variation which distance from hiatus of facial nerve to geniculate ganglion is distinct.
Our data will be very holpful for location of IAM during operation via middle cranial fossa approach.
