The Role of Patient Motivation in Single-Sided Deafness: Patterns in Treatment Selection and Cochlear Implant Outcomes.

Background/

Objectives

Single-sided deafness (SSD) treatment options include Contralateral Routing of Signal (CROS) or Bilateral Routing of Signal (BiCROS) systems, bone conduction devices, cochlear implants (CIs) and no intervention. Aligning treatment recommendations with patient motivations is fundamental for satisfaction and successful outcomes. At our institution, a structured telehealth consultation precedes formal testing and includes treatment motivation exploration and comprehensive review of all interventions. This study examined SSD treatment motivations and their association with pursuing cochlear implantation.

Methods

Adults who completed a pre-treatment SSD telehealth consultation over a four-year period were identified. Charts were retrospectively reviewed for demographics, SSD characteristics, treatment motivations, treatment choice, and CI outcomes.

Results

A total of 122 adults were evaluated. Mean age was 56.3 (±13.0) years, and 59.8% were male. Mean SSD duration was 10.8 (±15.8) years. The most common etiology was sudden sensorineural hearing loss. The top primary motivations were improving overall hearing (23.0%), restoring hearing to the deaf ear (22.1%), and improving hearing in noise (21.3%). Most patients (45.1%) opted for a hearing aid, CROS or BiCROS system; 38.5% chose CI; and 14.8% declined treatment. Only 57.4% of those who selected CI had the implant, primarily due to surgery avoidance (31.5%) and insurance limitations (10.5%). Motivation did not predict treatment choice or CI receipt. Among CI recipients (n = 27), those motivated by hearing restoration demonstrated poorer speech outcomes and datalogging.

Conclusions

Improving overall hearing and restoring hearing to the deaf ear were the most common motivations for seeking SSD treatment. Adult CI recipients had similar motivations to those who chose non-surgical options.
