Implantierbare Knochenleitungs- und aktive Mittelohr-Hörsysteme

Abstract

The majority of patients with moderate to severe hearing loss can be supplied with conventional hearing aids depending on severity and cause for hearing loss in a satisfying way. However, some patients either do not benefit enough from conventional hearing aids or cannot wear them due to inflammatory reactions and chronic infections of the external auditory canal or due to anatomical reasons. For these patients there are fully- and semi-implantable middle ear and bone conduction implants available. These devices either directly stimulate the skull (bone conduction devices), middle ear structures (active middle ear implants) or the cochlea itself (direct acoustic stimulation). Patients who failed surgical hearing rehabilitation or do not benefit from conventional hearing aids may achieve a significant better speech understanding and tremendous improvement in quality of life by implantable hearing devices with careful attention to the audiological and anatomical indication criteria.

The prevalence of hearing loss and use of hearing aids among adults in Germany: a systematic review

“…There is no literature available on treatment coverage by implantable hearing devices and cochlear implants in the general population. Furthermore, indications for pertinent operations are still a matter of current scientific discussion [14]. …”

“…For example, it was reported that only 16% of those requiring treatment are receiving an adequate intervention in form of hearing aids [12]. Taking into account that people with hearing loss can greatly benefit from the use of hearing devices (such as hearing aids), implantable hearing systems (such as active middle ear or cochlear implants) and speech therapy [13, 14], early recognition of this symptom in mandatory.…”

Der Mini-Audio-Test (MAT) – eine Screeningmethode auf Schwerhörigkeit für Haus- und Fachärzte

“…In der Regel wird eine Presbyakusis durch die Anpassung geeigneter Hörgeräte ausgeglichen [6]. Weitere Behandlungsmöglichkeiten sind implantierbare Hörsysteme wie aktive Mittelohrimplantate (AMEI), Knochenleitungsimplantate oder Cochlea Implantate (CI) [7].…”

Implantierbare Knochenleitungs- und aktive Mittelohrhörsysteme

“…die nicht optimale Passform, Verschlusseffekte des Gehörgangs oder Einschränkungen bei Wassersportaktivitäten. Zu den medizinisch-anatomischen Einschränkungen lassen sich chronische Otitiden mit Otorrhoe, Unverträglichkeiten gegenüber Silikon, Fehlbildungen des äußeren Ohres, ein Zustand nach Mittelohroperation oder die Anlage einer offenen Mastoidhöhle mit weitem Gehörgang beschreiben [5].…”
