Abstract:
OBJECTIVE:To explore the high resolution CT image of temporal bone in infants with hearing loss, and its value in evaluating the cause of hearing loss.
METHOD:In 2005, 0.12 million newborns have been included in the hearing screening system in Shanghai, and 1077 infants have failed to pass the hearing screening. One hundred and eight four infants were diagnosed as congenital hearing loss from mild to profound. A temporal bone HRCT scanning was performed to these infants.
RESULT:Among the 184 patients with congenital hearing loss, HRCT showed that 26 cases (14.1%) were associated with external ear malformation, and 21 cases (11.4%) were associated with middle ear malformation, 31 cases (16.8%) associated with inner ear malformation. The patients with inner ear malformation included 12 cases with Mondini malformation, 1 case with common cavity malformation, 6 cases with large vestibule malformation, 5 cases with internal auditory canal abnormalities, and 10 cases with vestibule, semicircular canals abnormalities. In addition, there were 20 cases (10.8%) with fluid in middle ear.
CONCLUSION:HRCT image play an important role in the differential diagnosis and treatment of infants with congenital hearing loss.
