Anatomic dissections at that time suggested that most ganglion cells could be excised by slicing away the ganglion from the internal genu of the facial nerve.
It is known from analysis of histologic sections and ganglion stains that the ganglion fibers lie anterior to the internal genu. (1) In addition, because the nerve is circular, the ganglion cells form a concave attachment so that they extend for a short distance over the superior edge of the motor trunk of the facial nerve and over the inferior edge of the facial nerve.
