ABSTRACT

OBJECTIVE@#To compare the therapeutic effect of electro-nape-acupuncture (ENA) combined with hyperbaric oxygen therapy (HBOT) and single HBOT on refractory flat descending idiopathic sudden sensorineural hearing loss (ISSNHL).@*METHODS@#A total of 78 patients were randomized into an ENA combined with HBOT (ENA+HBOT) group and a HBOT group, 39 cases in each one. Patients in both groups were treated with oral extract of ginkgo biloba leaves and mecobalamin tablets. On the basis of the conventional medication treatment, HBOT was adopt in the HBOT group. On the basis of the treatment in the HBOT group, electro-nape-acupuncture was applied at Fengchi (GB 20), Gongxue (Extra), Zhongzhu (TE 3), Waiguan (TE 5) and Yifeng (TE 17), Tinggong (SI 19), Tinghui (GB 2) and the vertigo-auditory area of affected side in the ENA+HBOT group. Pulse acupuncture instrument was connected at Fengchi (GB 20) and Gongxue (Extra) for 30 min (with continuous wave, 2 Hz in frequency), the needles were retained for another 30 min after electroaupuncture. The treatment was given once a day, 6 times a week for 4 weeks in both groups. Before the treatment and 2,4 weeks into the treatment, the average auditory threshold, the scores of tinnitus handicap inventory (THI) and dizziness handicap inventory (DHI) were observed, and the therapeutic effect was evaluated in both groups.@*RESULTS@#Compared before treatment, the average auditory threshold, the scores of THI and DHI of 2,4 weeks into the treatment were decreased in both groups (0.05).@*CONCLUSION@#Electro-nape- acupuncture can improve the mean auditory threshold and the symptoms of tinnitus and dizziness in patients with refractory flat descending idiopathic sudden sensorineural hearing loss.
