Audiological Aspects
Intensive counselling needed to raise realistic expectations
1. "The rapid increase of hearing-related QoL after 3-6 months ... indicates that our patients had little problems with adapting to the new hearing sensation provided by the Cl." (Muigg et al. 2019)
2. "An interesting finding is that in our case series even patients with long-standing deafness (..) were able to rapidly integrate the electric stimulation into their acoustic normal hearing, and to improve their speech perception scores in complex listening conditions as early as at 3 months post implantation." (Tavora-Vieira et al. 2013)
3. "Another factor that may contribute to the early and consistent benefit observed for Cl recipients in the present study is the relatively deep insertion of the (..) standard electrode array. Monaural speech perception and binaural processing can be degraded by a shift in the mapping of place to frequency. " (Buss et al. 2018)
4. "Relatively accurate and asymptotic pitch perception was observed at the 1-month interval, indicating either very rapid acclimatization or the provision of familiar place and rate cues. Early availability of appropriate pitch cues could have played a role in the early improvements in localization and masked speech recognition previously observed in this cohort." (Dillon et al. 2019)

Medical Aspects
Cl requires life long aftercare
1. "After implantation, the surgeon is responsible to organize and perform a life-long follow-up. It refers to the technical checkup as well as the settings of the implants. Furthermore, regular updates of the software and hardware are necessary since they make progress of the implant technology useable for the patients. " (Lenarz 2018)
Medical Aspects
Not applicable in cases with congenital cochlear nerve deficiency (e.g. congenital SSD) or acquired nerve absence (e.g. following vestibular schwannoma surgery)
1. "Congenital deafness (n= 24). More than 50% (n=14) of the congenitally deaf children showed aplasia / hypoplasia of the cochlear nerve in MRI; therefore they did not qualify for Cl surgery" (Arndt et al. 2015)
Medical Aspects
MRI artifacts
1. "Imaging artifact only very rarely impedes adequate visualization of the ipsilateral IAC or CPA in Cl recipients. In anticipation of the need for further IAC and CPA imaging, it would be advisable to place the receiver in an exaggerated superior-posterior position to further decrease obscuring artifact." (Schwartz et al. 2020)
2. "Metallic implants are a significant concern because of their interaction with the complex MR environment, which can introduce significant force, voltage, heat, image artifact, demagnetization, and potential device malfunction." (Shew et al. 2019)
Patient-reported Aspects
Need for rehab
1. "Nevertheless, several studies have defended the importance of intensive auditory training in order for all Cl users with SSD, regardless of age, to achieve optimal outcomes." (Tavora-Vieira et al. 2019)
Patient-reported Aspects
Acceptance of Cl hearing
1. "Electrical Stimulation via a Cl resulted in a significant reduction in tinnitus loudness (...)." (Van de Heyning et al. 2008)
