Abstract

is mostly associated with inner ear malformations and Cerebrospinal Fluid (CSF) leakages. With bacterial meningitis, inflammation may spread to the healthy ears and cause bilateral deafness in some cases. In this paper, two cases of congenital inner ear malformations are presented. In Case 1, inflammation of the bacterial meningitis spread to the healthy ears and cause bilateral deafness and the patient received cochlear implant surgery. In Case 2, there was no history of meningitis or any findings of CSF leakage on CT, but the patient received exploratory surgery and repair of the potential risk of CSF leakage. In recent years, inner ear malformations have been increasingly diagnosed after newborn hearing screening, without any signs of meningitis. Early identification of the specific type of inner ear malformation and determining the associated risk of meningitis are vitally important. In cases of inner ear malformations with a high risk of CSF leakage and bacterial meningitis, surgical repair of CSF leakage should be considered before bacterial meningitis develops.
