Answer

Answer

See the list below:

  • Know the anatomic layers of the scalp and the course of the facial nerve.

  • Map out the course of the superficial temporal artery with the use of Doppler ultrasonography.

  • Avoid injecting epinephrine near the artery, as this can lead to spasm.

  • Obtain at least a 3-cm segment of artery to aid in diagnosis.

  • Provide a relaxing environment in the procedure room and administer adequate local anesthesia.

  • To avoid incisional alopecia, bevel the scalp incision parallel to the plane of the hair shafts and avoid electrocautery of bleeding skin vessels, if possible.
