Hearing Loss in A Child with Hydrocephalus
Background: Hydrocephalus in children is a complex condition that can affect neurodevelopmental
disorders, including hearing impairment. Changes in pressure and amount of cerebrospinal fluid (CSF)
could cause endolymph hydrops which results in inner ear dysfunction. Objective: To study the mechanism
of how hydrocephalus could cause hearing loss. Case: A 1 year 7 months old girl with hydrocephalus
and global development delay, and hearing loss. The patient underwent hearing tests with Otoacoustic
Emission (OAE), tympanometry, and Evoked-Auditory Brain Response (ABR). The patient underwent
ventriculoperitoneal (VP) shunt surgery and hearing rehabilitation. Three months post-surgery patient
could respond to sound stimulation. Clinical question: How is the mechanism of hydrocephalus in
inducing hearing loss? Method: Literature search was performed through PubMed and Google Scholar,
with “hearing loss” AND “hydrocephalus” AND “children” as the keywords. The search obtained 101
journals. Result: Publications that fulfilled the inclusion criteria were 4 journals. Hearing loss was caused
by fourth ventricular pressure. Hydrocephalus could also cause hearing loss through the mechanism of the
relationship among perilymph, endolymph, and CSF pressure. VP shunt or ventriculotomy was supposed
to be able to improve the inner ear function. Conclusion: Hydrocephalus causes endolymphatic hydrops
which results in hearing loss.
