The mean onset time was 5.42 days. Four children had tinnitus and 3 patients showed dizziness. For the possible etiology. 2 cases had mumps. 6 cases had definite upper respiratory infections history, one experienced trauma, and another one took ototoxic drugs. Five patients were proved to come down with the large vestibular aqua duct syndrome by the CT scan. Among the 21 ears. 7 ears were diagnosed severe hearing loss and 14 ears were diagnosed profound hearing loss. After the treatment of 7 days, 6 ears were cured, one car showed effective change. and 14 cars came out to be ineffective, with the total effective rate of 33.3%. After the 14 days' treatment, there was no improvement for 5 patients.
