Cortical Maturation in Children with Conductive, Mixed, and Unilateral Hearing Losses
Background: The P1 cortical auditory evoked potential (CAEP) response is a biomarker of auditory cortex maturation. This biomarker has been measured in children with Sensorineural hearing loss or ANSD who have no hearing devices or to determine their candidacy for hearing aids and/or cochlear implants to provide information about cortical maturation before and after hearing treatment. This information can provide guidance on hearing interventions for these children. However, there is a lack of this information on the P1 biomarker in children with conductive and mixed losses, including those who are candidates for, or utilizing osseointegrated hearing devices. The goal of this study is to examine cortical maturation in children with conductive, mixed hearing losses and/or single-sided deafness who use or are considering use of osseointegrated implants.
Methods: The P1 CAEP biomarker will be measured in response to different stimuli and in a variety of conditions including unaided, aided, and ear-specific information, with and without masking. We will first test multiple conditions to understand how contralateral masking may affect P1 responses, such as in the case of unilateral microtia/atresia where we will isolate the ear with hearing loss to provide ear-specific information. We will present case studies of P1 responses in those with congenital conductive/mixed losses and unilateral losses.
Conclusions: P1 biomarker provides useful information for examining cortical maturation in children with conductive and mixed losses, including those who utilize osseointegrated devices.
- to explain importance of the P1 biomarker
- to identify impact of conductive, mixed, and unilateral hearing loss on cortical maturation
- to recognize how masking affects cortical response collection
