Unilateral common cavity deformity: Recurrent meningitis due to insufficient newborn hearing screening

Insufficient newborn hearing screening may leave the other ear with undetected hearing loss. Subsequently, the missed pathology behind the impairment may have potential risk for severe infections. We describe a case of recurrent Streptococcus pneumoniae meningitis in an infant with unilateral common cavity deformity. The diagnosis of the deaf left ear was delayed due to insufficient newborn hearing screening and not until the second meningitis the pathology behind the deafness was confirmed. Subtotal petrosectomy was performed unsuccessfully and resulted in another meningitis. We highlight the importance of proper newborn hearing screening and surgical technique to treat cochlear malformations.
