Results are expressed as means with SD in parentheses or ranges in square brackets. p values of significance are italicised. FU, follow-up; HL, hearing loss; PTA, pure-tone average for 0.5, 1.0, 2.0, and 4.0 kHz; AC, air conduction.

The first implanted ear is designated as ipsilateral for 4 bilateral users for correlations.
