Moderator, Dr. Michael M. Paparella: We will consider idiopathic Bell's palsy incidence, etiology, and prognostic significance of symptoms and signs. Then we will get into treatment, both surgical and medical, and we will consider some special Bell's situations, such as recurrent and bilateral.

I would like to ask Dr. Valvassori to give us an idea of what he can do roentgenologically in identifying lesions that might not be Bell's.

Galdino E. Valvassori: The infratemporal portion of the facial nerve canal can be radiographically demonstrated by tomography.

The first and second portion of the facial nerve canal is best visualized in the frontal and oblique sections. Just superolateral to the cochlea, you can visualize the two holes produced by the first and by the second portion of the facial nerve just posterior to the genu.

In the region of the oval window, you can visualize the facial nerve canal quite clearly
