Auditory Neuropathy in North Richland Hills
Auditory neuropathy spectrum disorder (ANSD) is a hearing condition in which the outer hair cells of the cochlea function normally, but the transmission of sound from the cochlea to the brain is disrupted. At North Hills ENT in North Richland Hills, our audiologists and ENT specialists are trained to diagnose and manage this complex condition.
What Is Auditory Neuropathy?
Unlike typical sensorineural hearing loss where outer hair cells are damaged, auditory neuropathy involves dysfunction of the inner hair cells, the synapses between hair cells and the auditory nerve, the auditory nerve itself, or the brainstem pathways. This disruption affects the synchrony (timing) of neural signals, making speech understanding particularly difficult — even when pure-tone thresholds appear normal or near-normal.
Who Is Affected?
ANSD can affect infants, children, and adults. Risk factors include premature birth, neonatal jaundice requiring exchange transfusion, low birth weight, hypoxia at birth, family history of auditory neuropathy, and certain genetic mutations (e.g., OTOF gene encoding otoferlin).
Symptoms
- Normal or near-normal pure-tone hearing thresholds but very poor speech discrimination
- Speech understanding that is worse in noise than expected
- Fluctuating hearing ability
- Difficulty following conversations
- Tinnitus in some cases
Diagnosis
Auditory neuropathy is diagnosed through a combination of tests. Key findings include present otoacoustic emissions (OAEs) indicating outer hair cell function, and absent or severely abnormal auditory brainstem response (ABR) indicating neural dyssynchrony. A comprehensive evaluation at North Hills ENT includes all necessary testing.
Treatment and Management
- Hearing aids: Benefit varies; some patients do well, others do not
- Cochlear implants: Often the most effective option, especially for children
- FM systems and assistive listening devices
- Auditory training and speech therapy
- Communication strategies and educational support for children
