“… 22 Our previous study also suggests that the physiological functions of the peripheral auditory system in patients with Mondini malformation may divide into two opposite extremes, as revealed by either a robust EABR or the absence of the EABR. 9 Therefore, in addition to cochlear size, other factors such as the severity of cochlear malformation may also contribute to auditory conduction function. This study has a limitation.…”

Objectives To investigate the relationship between auditory pathway function and cochlear size in deaf children with a radiologically normal inner ear or Mondini malformation. Methods Thirty‐five deaf children without inner ear malformations (IEMs) and forty cases with Mondini malformation were included in this study. The electrically evoked auditory brainstem responses (EABRs) evoked by electrical stimulation at the round window niche (RWN) and round window membrane (RWM) were recorded during cochlear implantation (CI) surgery. The anatomical parameters of the cochlea were assessed by high‐resolution computed tomography and OTOPLAN 3‐D construction software. Correlations between EABRs and cochlear sizes were analyzed. Results The EABR thresholds and/or latencies were negatively correlated with the basal cochlear diameter, cochlear width and/or cochlear duct length in both patients without IEMs and those with Mondini malformation. Conclusion The physiological function of the peripheral auditory system depends on the anatomical structure of the cochlea to an extent. A larger cochlear size appears to be associated with better auditory conduction function. Our findings may be beneficial to selection of the proper electrode type and prediction of postoperative auditory rehabilitation. Level of Evidence Level 4.

“… 8 Our previous study also demonstrated a lower extraction rate of the electrically evoked auditory brainstem response (EABR) in patients with Mondini malformation than in those without IEMs. 9 Whether the auditory pathway function involved in the cochlea with Mondini malformation is related to cochlear size remains unclear.…”

“…The two later components (eIII and eV) indicate that the signal has reached the brainstem at a higher level along the auditory pathway (the superior olivary nucleus and the inferior colliculus). We previously reported that the EABR response rates were 80% and 55% for patients with no IEMs and those with Mondini malformation, respectively (Zhu et al, 2022). The high EABR response rate (95%) found in the present study suggests that a coarse neural pathway still develops in children with severe-to-profound hearing loss (Lassaletta et al, 2017).…”

This study investigates the effect of hearing aid use on the peripheral auditory pathways in children with sensorineural hearing loss prior to cochlear implantation, as revealed by the electrically evoked auditory brainstem response (EABR). Forty children with hearing aids were recruited. Half of them had normal inner ear structures and the other half had inner ear malformations (IEMs). The EABR was evoked by electrically stimulating the round window niche (RWN) and round window membrane (RWM) during the cochlear implantation operation. The onset age of hearing aid use was significantly correlated with the peak latencies, but not amplitudes, of the wave III (eIII) and wave V (eV). Higher EABR thresholds were found for RWN stimulation than for RWM stimulation and in the children with IEMs than in those without IEMs. Our study provides neurophysiological evidence that earlier use of hearing aids may ameliorate physiological functions of the peripheral auditory pathway in children with and without IEMs. The EABR evoked by the electrical stimulation at RWM is more sensitive compared with that at RWN for evaluating functions of the auditory conduction pathway.
