The duration of hearing loss indicates the estimation of the period during which the patients are suffering from hearing loss. The values of residual hearing correspond to the thresholds for the nonimplanted ear (obtained during a tonal audiometry test). For frequencies higher than those reported here, the thresholds are over 90 dB SPL. Onset indicates the time (in days) between cochlear implantation and the implant onset. T0 indicates the time (in days) between the implant onset and the first tomography, while T1 indicates the time (in months) between the implant onset and the second tomography.
