Location

Behind the ear lobe, in the depression anterior to the lower end of the mastoid process, between it and the mandible.

How to locate: With the mouth slightly open, press the ear lobe back against the head; the point is in the tender hollow it covers, between the mandible and the front of the mastoid process.

Regional anatomy: The needle passes through the skin and subcutaneous tissue into the parotid gland behind the ramus of the mandible; the facial nerve trunk emerges from the stylomastoid foramen deep to the point.

Distances are in cun, a proportional unit — how to measure.
