Imaging features of children with hearing loss

Objectives: To determine the related factors of sensorineural hearing loss and the imaging features of this issue among children in Children’s Hospital 1.Methods: From July 2022 to July 2023, a prospective study was conducte on 72 children with a diagnosis of sensorineural hearing loss at the Children’s Hospital 1.Results: The degree of hearing loss most severe-to-profound hearing loss (≥ 90 dB) was 51,4% as many as 46 children (63.9%) with asymmetrical hearing loss in most of the subjects. Most of the children with bilateral congenital sensorineural hearing loss (SNHL) are in the age > 5 years old (mean age: 5.8 years). There were 19.4% of cases having abnormal inner ear images on temporal bone computed tomography (CT scan) Through brain, the percentage of abnormal cranial nerve 8th was 6.6%, including 2 cases of aplasia cranial nerve 8th and 2 cases of hypoplasia cranial nerve 8th.Conclusion: There was a delay in the diagnosis of prelingual sensorineural hearing loss, with a high proportion of the severe - to - profound among children presenting with a diagnosis. Besides diagnosing the causes of hearing loss, CT scan and MRI also assist in determining the feasibility of surgical intervention based on the images they provide. Audiometry tests can indicate the extent of hearing loss and profound deafness caused by cochlear damage. However, when a CT scan is conducted, an MRI can offer us precise information regarding the causes, potential recovery, and the techniques and approaches for intervention.
