To evaluate the influence of auditory deprivation on sequential cochlear implants in postlingual patients, comparing the ear with shorter deprivation (ESAD), longer deprivation (ELAD), and the bilateral condition (BIL).
Findings suggest that longer auditory deprivation in the second-implanted ear may worsen outcomes in sequential cochlear implant users; clinicians should weigh deprivation duration when counseling and timing second-side implantation, though effect size and clinical thresholds require confirmation from the full study.
Optimizing the timing of second cochlear implant surgery is a common clinical dilemma, and quantifying the impact of asymmetric deprivation could inform candidacy guidelines and counseling for sequential bilateral implantation.
- 01Asymmetric auditory deprivation between ears may negatively affect cochlear implant outcomes in sequential procedures.
- 02Study focuses on postlingual patients (those who lost hearing after learning to speak/understand language).
- 03Shorter deprivation duration in the implanted ear was compared with longer deprivation to isolate the effect.
- 04Findings could influence timing recommendations for second cochlear implant surgery.
