Where does the temporal branch of the facial nerve lie during preauricular dissection?

The temporal branch of the facial nerve typically lies superficial to the superficial temporal fascia during preauricular dissection. This anatomical positioning is crucial for surgeons to understand in order to avoid nerve damage during procedures in the preauricular area. The superficial temporal fascia provides a protective layer over the structures beneath it, and knowing that the temporal branch runs above this fascia allows for careful dissection and manipulation during surgery, minimizing the risk to the nerve.

This understanding is particularly important during procedures like facelift surgery or parotid gland surgeries, where access to the preauricular region is necessary. Proper identification and preservation of the temporal branch help to ensure that facial movements remain unaffected postoperatively.
