⭐⭐⭐Tragal pointer,⭐⭐⭐

⭐⭐⭐The tympanomastoid suture line⭐⭐⭐

⭐⭐⭐The posterior digastric muscle⭐⭐⭐

The tragal pointer refers to the
tragus cartilage, which “points” to the location of the nerve one centimeter anterior, inferior, and  deep to the cartilage.

Another method of identification is to follow the tympanomastoid suture line
inferiorly to its drop-off point. Six to eight millimeters medial to this point, the facial nerve can be  found passing through the stylomastoid foramen.

Finally, the nerve can be located just medial to the insertion of the posterior belly of the digastric on the mastoid.
