The Effects of Sphenopalatine Ganglion Acupuncture on Nasal Function

"The acupuncture point was selected in the sphenopalatine ganglion (unilateral side). The acupuncture needle was inserted from the lower border of the zygomatic arch, slightly posterior to the suture protuberance between the zygomatic process and temporal process. The needle was rotated until the participant felt de-qi sensations."

The acupuncture point was selected same to the sphenopalatine ganglion. But the needle was inserted at the selected acupuncture site to a depth of only 2-3cm, and the procedure of rotating, twirling and thrusting the needle was repeated, in order to blind the subject to the sham treatment.
