“…19-22 However, more recent studies indicate that limited speech detection and discrimination and, very occasionally, higher levels of auditory performance may be observed in these children. 23-27 The recent innovative proposal of offering ABIs as first-line treatment in children with CND, corroborated by significantly better outcome compared with children fitted with CIs, 3,7-11,14-16 complicated the decision with regard to the best treatment option for children with CND and generated a pivotal therapeutic dilemma.…”

“…earing restoration in children with cochlear nerve deficiency (CND) is a therapeutic challenge, with conflicting reports describing children who, despite cochlear nerve hypoplasia or aplasia on magnetic resonance imaging (MRI), show auditory responses to different procedures, including simple amplification, 1,2 cochlear implants (CIs), [3][4][5][6] and auditory brainstem implants (ABIs). [7][8][9][10][11] An evident caveat of most of these studies is the very small number of subjects in any given subgroup comparison.…”

In children with cochlear nerve deficiency, patients fitted with cochlear implants did not develop speech understanding and production. Those fitted with auditory brainstem implants had the opportunity to develop open-set speech perception, acquiring verbal language competence using oral communication exclusively and participating in mainstream education. The overall complication rate of auditory brainstem implants was not greater than that of cochlear implants.

“…These results are consistent with reports by several authors . [4][5][6][7]24,25 Considering the older ages of the children of the present cohort at the time of ABI, compared to the very young age at which CI is currently performed,26-32 we believe that ABI holds great promise for patients with narrow lACs and CND if it is performed early.…”

Objectives We compared the perceptual auditory abilities of 21 children with suspected cochlear nerve deficiency (CND) and a surgically verified absent cochlear nerve (CN) who first underwent cochlear implantation (CI) and subsequently underwent auditory brainstem implantation (ABI). Methods In this retrospective cohort study, from 2000 to 2011, 21 children initially underwent CI at an outside institution and failed to progress in their perceptual auditory abilities. Before CI, all of the children had severe to profound sensorineural hearing loss and a diagnosis of CND. Magnetic resonance imaging (MRI) documented an absent CN in 13 children and a small CN in 8 children. We performed explantation of the cochlear implant and simultaneous ABI on the same side. We performed MRI if no previous MRI results were available. All surgical videos were reviewed to determine the presence or absence of the CN. Measures of the patients’ perceptual auditory abilities obtained after CI and after ABI were converted to the Category of Auditory Performance (CAP) scale. Results At surgery, all patients demonstrated an absent CN. After CI, all patients had a CAP score of 2 or less (mean, 0.52 ± 0.68). After ABI, all patients had a CAP score of 2 or more (mean, 4.33 ± 1.68); the improvement was statistically significant (p < 0.001). The complication rates were similar for CI and ABI. Conclusions In this cohort of patients who had poor performance after CI, ABI achieved significantly improved performance as measured by the CAP and was shown to successfully rehabilitate hearing. Cases of a small CN may in reality represent an absent CN. Although this cohort was selected from patients with failed CI, the results have implications for the selection of device for patients with CND, in that ABI is a potential alternative to CI in select cases. In patients who fail to progress with intensive rehabilitation with CI or who have no progression in evoked auditory brainstem response, ABI must be considered early.
