Profound sensorineural deafness can be caused by several types of infections that affect the inner ear structures. Key infections associated with this condition include:

Viral Infections: The mumps virus is a common cause of severe sensorineural hearing loss, while measles and influenza are also known causes. Additionally, cytomegalovirus (CMV) is a major cause of congenital deafness in infants.123
Maternal Infections: Rubella (German measles) contracted by a mother during pregnancy can cause severe damage to the organ of Corti, leading to profound hearing impairment in the child.2
Bacterial and Other Infections: Meningitis is a known cause of profound sensorineural deafness. Furthermore, labyrinthitis—an inflammation of the inner ear—can result in permanent hearing loss if it leads to suppuration (pus formation). This condition can arise from various infections, including syphilis, otitis media, and mastoiditis.245

Early recognition of these conditions is essential for appropriate intervention, such as the consideration of a cochlear implant for children.2
