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.
