Resolution of auditory neuropathy spectrum disorder after shunt placement in a patient with hydrocephalus: A case report.

PURPOSE: There have been previous case reports suggesting the resolution of both sensorineural hearing loss and retrocochlear involvement through the management of hydrocephalus with shunt placement. This is a case report of a patient with Auditory Neuropathy Spectrum Disorder (ANSD) that resolved after shunt placement in a patient with hydrocephalus.

MATERIALS AND

METHODS

Chart review of a single patient with a diagnosis of ANSD and hydrocephalus. Type of audiometric testing and results were document.

RESULTS

Patient is an infant who was diagnosed with hydrocephalus at birth and ANSD in the right ear at 3 months of age. Patient underwent shunt placement at 9 months old and had behavioral testing 2 months later. Audiometry showed normal behavioral audiometric thresholds with presence of ipsilateral and contralateral reflexes which is suggestive of resolution of ANSD.

CONCLUSIONS

This is a single case report of resolution of ANSD after shunt placement in a patient with hydrocephalus. Close monitoring and repeat audiological evaluation is recommended to follow these patients.
