Evaluation of Cochlear Implantation in Unilateral or Asymmetric Hearing Loss in Children.

Today, unilateral hearing loss must be assessed and managed just as bilateral hearing loss is. It is recommended to consider the auditory difficulties caused by the loss of stereophonic hearing and to offer auditory rehabilitation as early as possible. Studies show that hearing devices can be effective in certain cases and for specific auditory modalities. The prognostic factors for successful hearing aid adaptation are linked to early intervention and the presence of residual hearing (using a BiCROS system). However, the cochlear implant remains the only device capable of potentially restoring contralateral auditory function in cases of single-sided deafness (SSD) and severe to profound unilateral hearing loss with asymmetrical deafness

Impact of Anatomy-Based Cochlear Implant Programming on Early Performance

The purpose of this study is to evaluate the impact of different audio processor frequency settings on performance outcomes in new cochlear implant users using electric-only stimulation in the implanted ear with normal hearing to moderately severe hearing loss in the opposite ear.

Cochlear Implantation in Children With Asymmetric Hearing Loss or Single-Sided Deafness Clinical Trial

This is a two-phase study that compares performance growth pre-implant with current hearing aid (HA) technology versus post-implant with a cochlear implant (CI) in children with either asymmetric hearing loss (AHL) or single-sided deafness (SSD). Post-implant performance with a CI alone is expected to outperform pre-implant performance with a HA. The study also evaluates the effectiveness of bimodal hearing defined as a CI in the poor ear and a HA in the better ear for AHL or a CI in the poor ear and normal hearing in the better ear for SSD compared to pre-implant performance. The study examines factors contributing to CI outcomes.
