Patients reported a significant improvement in speech intelligibility in noise and greater benefit from BAHA compared with CROS hearing aids. Patients were satisfied with the device and its impact on their quality of life. No major complications were reported. Conclusion and significance BAHA is effective in unilateral deafness. Auditory stimuli from the deaf side can be transmitted to the good ear, avoiding the limitations inherent in CROS amplification.

A high index of suspicion is required for the diagnosis of such a forgotten entity.

Patients with UNSNHL had poor sound localization and laterality judgment abilities that did not improve with BAHA use.
