Thermal Effects of Acupuncture by the Infrared Thermography Test in Patients With Tinnitus.

Previous studies have confirmed the efficacy of acupuncture treatment for tinnitus. However, no relevant studies of the exact mechanism of acupuncture efficacy on tinnitus have been published. Enrolled participants with left-sided tinnitus received acupuncture treatment at TE3 and TE5. The acupuncture session lasted for 30 minutes. The infrared thermography (IRT) test of each participant's bilateral aural regions and visual analog scale scores were taken before and after the first acupuncture treatment session. Fifty-four participants accepted acupuncture treatment and the IRT test. The temperature differentials of both sides were reduced significantly, but the maximum, minimum, and average temperature of bilateral aural regions did not have a significant difference before and after acupuncture session. The acupuncture's effects for tinnitus were associated with the improvement of cochlear blood flow via the IRT test. We have planned a full-scale randomized controlled trial to find out more about the underlying mechanisms of acupuncture for tinnitus.
