Common clinical causes and audiological manifestations of unilateral hearing loss in children

Abstract

Objective:To analyze the common clinical causes and audiological manifestations of unilateral hearing loss in children, and to provide a basis for early prevention and intervention. Method:A retrospective analysis of 20 cases of children diagnosed with unilateral hearing loss was conducted. The medical history was collected, followed by audiological and imaging examinations. Result:The audiological performance of 20 children with unilateral hearing loss: 1 case of conductive deafness, whose hearing curve was flat and showed moderate hearing loss. There were 19 cases of sensorineural deafness, of which 1 case was moderate deafness, 16 cases were severe deafness, and 2 cases were extremely severe deafness. The imaging results showed that there were 1 case with transverse fracture of the temporal bone, 1 case with congenital cholesteatoma, 9 cases with dysplasia of the cochlear nerve, and 4 cases with malformation of the inner ear. The history of the two children was collected and there were clear congenital cytomegalovirus infection and mumps virus infection. The causes of the remaining 3 cases were unknown. Conclusion:Unilateral hearing loss in children is a common clinical diseasewith complex and diverse causes. Carefully analysis should be made to find out the causes and symptomatic treatment to provide a basis for early prevention and intervention of children's hearing.
