FACIAL NERVE (VII)

Middle Ear & Mastoid

1. From IAM the nerve bends back on itself at the geniculate ganglion (1st genu) just above the processus cochleaformis (with tensor tympani looping around it.)

2. Then it heads posteriorly until it curves around the superior aspect of the oval window to head inferiorly (2nd genu.) Here it lies just anterior (‘kissing’) to the lateral scc.
