Partial deafness (PD) causes a deprivation in hearing high frequencies. This leads to voice functional voice disorders. Study shows that PD is associated with changes in frequency, amplitude, noise, tremor, and voice irregularities. Partial deafness cochlear implantation (PDCI) has been proven to improve voice quality. The aim of the study was to evaluate the long-term voice effects of PDCI on voice....
Audiologists and surgeons counselling partial-deafness cochlear implant candidates should proactively discuss the risk of long-term voice changes and consider voice monitoring as part of follow-up care.
Voice disorders are an underrecognised long-term consequence of partial deafness cochlear implantation, and this finding may prompt revision of post-implant rehabilitation protocols.

Partial deafness cochlear implantation leads to long-term voice disorders due to high-frequency hearing deprivation.
