“…Measurable hearing and normal function of the facial nerve were maintained in 33-57% and 92-100% of patients, respectively [17,18]. The current indications for radiosurgery are (1) a growing tumor less than 30 mm in mean diameter, (2) the ipsilateral ear has no serviceable hearing, and (3) there is risk of brain stem compression or brain stem dysfunction. Treatment is generally indicated when there is a risk of brainstem compression, deterioration of hearing, and/or facial nerve dysfunction.…”

“…There were Wave V responses on both sides but the morphology and latencies were better on the left side compared to the right side, Kumar-Dutt Classification Type B on the left side and Type C on the right side [2]. With a special consent, cochlear implantation with Nucleus Freedom CI24RE(ST), was performed in the left ear with complete insertion (Fig.…”

Auditory Brainstem Implants have been recommended as the gold standard in hearing rehabilitation of Neurofibromatosis Type 2 patients who lose hearing completely in both the ears and the cochlear nerves are not stimulable. Some patients have undergone cochlear implantation, in whom the cochlear nerve was spared during surgery or have undergone stereotactic radiotherapy preserving the function of the cochlear nerve. Here we report a case in whom we chose cochlear implantation prior to any definitive treatment for the tumour itself during the 'wait and watch' period. The reasons in favour of this approach have been discussed in this article. Post switch-on the implant is benefitting the patient satisfactorily and she is on regular follow up for monitoring the bilateral tumours.

Die Cochlea-Implantation hat sich als Goldstandard der Hörrehabilitation für Patienten mit hochgradigem sensorineuralen Hörverlust etabliert und ist heute eine unverzichtbare Methode für diese Patienten. Angepasst an rasante Entwicklungen und die sich ergebenden vielfältigen Indikationserweiterungen, haben sich folgerichtig die Implantationsprinzipien subtil verfeinert. Diese Übersicht fasst aktuelle Entwicklungen zusammen, denen im klinischen Alltag wachsende Aufmerksamkeit und eine zunehmende Anwendung zuteil wird.

“…A classification proposed by Dutt et al (the Kumar-Dutt classification) (Table 2) was used to classify the wave V responses obtained. 22 The ear for implantation was decided based on the type of transtympanic electrically evoked ABR waveform. Specifically, the ear with a better waveform and type of transtympanic electrically evoked ABRs according to the Kumar-Dutt classification was chosen.…”

Cochlear implantation in auditory neuropathy spectrum disorders: role of transtympanic electrically evoked auditory brainstem responses and serial neural response telemetry

Objective To evaluate the utility of pre-operative transtympanic electrically evoked auditory brainstem responses and post-operative neural response telemetry in auditory neuropathy spectrum disorder patients. Methods Four auditory neuropathy spectrum disorder patients who had undergone cochlear implantation and used it for more than one year were studied. All four patients underwent pre-operative transtympanic electrically evoked auditory brainstem response testing, intra-operative and post-operative (at 3, 6 and 12 months after switch-on) neural response telemetry, and out-patient cochlear implant electrically evoked auditory brainstem response testing (at 12 months). Results Patients with better waveforms on transtympanic electrically evoked auditory brainstem response testing showed superior performance after one year of implant use. Neural response telemetry and electrically evoked auditory brainstem response measures improved in all patients. Conclusion Inferences related to cochlear implantation outcomes can be based on the waveform of transtympanic electrically evoked auditory brainstem responses. Robust transtympanic electrically evoked auditory brainstem responses suggest better performance. Improvements in electrically evoked auditory brainstem responses and neural response telemetry over time indicate that electrical stimulation is favourable in auditory neuropathy spectrum disorder patients. These measures provide an objective way to monitor changes and progress in auditory pathways following cochlear implantation.
