We report a newborn male with hydrocephalus that clinically improved hearing loss after the shunt and also endoscopic procedures. these changes were also documented with audiograms. a newborn 4-month-old male presented with non-syndromic bilateral hearing loss with hydrocephalus. in an attempt to improve his hydrocephalus he underwent two operations; first endoscopic third ventriculostomy,and then ventriculo-peritoneal shunt. after 10 months,his magnetic resonance images displayed double compartment hydrocephalus and shunt malfunction. the otologic work-up revealed sensorineural hearing loss. therefore,endoscopic the compartments fenestration and catheter placement into the compartments and connection with ventriculo-peritoneal shunt was performed. after the third procedure,he had a significant improvement in intracranial pressure findings and hearing clinically. these changes were documented with audiograms. non-syndromic hearing loss with hydrocephalus may be treatable by improvement of high cerebrospinal fluid pressure level,if the hearing loss is reversible period. the effect of cerebrospinal pressure levels on intra-cochlear fluid pressure and hearing is briefly discussed.
