Abstract
The method of using the anterior margin of the mastoid process (the most inferior point of the tympanomastoid fissure) to find out the facial nerve at parotidectomy is described. This marker can be easily palpated and visualized after considerable dissection. The main trunk of the facial nerve is located 1 cm deep from this point. This marker is considered to be extremely useful, because (1) it is easy and safe to find, (2) it is constant and fixed in its position, and (3) the point leads to the stylomastoid foramen.
