Objective Clinical effect observations of electroacupuncture combined hyperbaric oxygen chamber therapy for Tinnitus patients. Methods Divide 90 Tinnitus patients into two 45-patient groups according to random number table—the treatment group（71 Ears）and the contrast group（66 Ears）. Offer the contrast group with pure acupuncture therapy at main points：Tinggong（SI19）， Tinghui（GB2）， Yifeng（SJ17）， Fengchi（GB20）and points of syndrome differentiation（no AE therapy）. Offer treatment group with the same therapy but also AE therapy at Tinggong（SI19）， Tinghui（GB2）， Yifeng（SJ17） and hyperbaric oxygen chamber treatment. Give efficacy evaluation for two groups after 3 phases with statistics software SPSS 17. 0 by specialist. Results The total effective rate of treatment group（71 ears） is 90. 1% — the number of ears in 3 efficacy levels are 50（markedly）， 14（effective）， 7（invalid）. The total effective rate of contrast group is 77. 3%—the number of ears in 3 efficacy levels are 23（markedly）， 28（effective）， 15（invalid）. The total effective rate of treatment group is significantly better than this index of contrast group；there is statistically significant difference in two groups（P<0.05）. And the effective of treatment group is significantly better than contrast group in Tinnitus levels according to 6-part evaluation：Tinnitus occurring condition， impact of sleep， lasting time， impact on daily time（the lives and work）， effects on mood， patients’ subjective feeling， there is statistically significant difference in two groups（P<0.05）. Conclusion The electroacupuncture combined hyperbaric oxygen chamber therapy for Tinnitus patients that has significant effect is worthy of clinical application—no adverse reactions， superior effect than pure acupuncture therapy.
