Aerotitis media occurs frequently among flyers. 40 cases have been treated with electro- acupuncture in our hospital with satisfactory results. Xiaguan was selected as local point and Hegu as distal point. The patients were needled once a day or every other day. The total rate of effectiveness was 90.0%. According to Western medicine, this disease is due to poor pressure-equilibrating function of the Eustachian tube. The mechanism of treating this disease was explained by traditional Chinese medicine and western medicine theory.
