Abstract
117 cases of unilateral hearing loss in children who visited in our clinic from 1985 to 1994 and were observed for over five years were studied. The patient group included 72 (62%) males and 45 (38%) females. The age range was 2 to 15 years old, and there was a peak of incidence at the 6-8 years old group. The hearing level of 8 ears (7%) were ranged in 0-30dB, 10 ears (9%) in 31-60dB, 21 ears (18%) in 61-90dB and 78 ears (67%) in over 91dB in average pure tone audiogram. There were 15 cases (13%) complaining of tinnitus, 4 cases (3%) of dizziness, 3 cases (3%) of functional hearing loss in the contralateral ear and 2 cases (2%) of another cochlear symptoms without alter the hearing level. There were 2 cases whose hearing loss were improved, 2 cases whose hearing loss were fluctuated with tinnitus or dizziness and 3 cases whose contralateral hearing level were changed with or without cochlear sympton. The long term follow up for unilateral hearing loss in children is necessary.
