The global auditory brainstem implant market size was USD 61.92 Million 2020 and is expected to register a revenue CAGR of 3.6% during the forecast period. Rapid advancements in the neuroprosthetic technology, increasing prevalence of inner ear and nerve abnormalities, and technological upgrades in external speech processor and receiver stimulator technology in auditory brainstem implants are key factors expected to drive market revenue growth over the forecast period. In addition, growing need for auditory brainstem implants in patients who are ineligible for cochlear implant surgery due to abnormalities in cochlea and cochlear nerve is another key factor expected to fuel revenue growth of the market going ahead.
Auditory Brainstem Implant (ABI) is a neuroprosthetic device that provides auditory sensations to patients who have compromised auditory nerve function and have anatomical barriers that do not provide a suitable location for cochlear implants. ABI was designed for patients with type 2 neurofibromatosis (NF2) whose auditory nerve function was damaged during tumor removal from the cranial nerve and has since then been used to provide auditory perception in patients having profound hearing loss. The implants stimulate the Cochlear Nucleus (CN) through an array of surface electrodes wherein the stimuli are controlled by external processor that has been programmed using processing and stimulation techniques developed for cochlear implants. Auditory brainstem implants are playing a crucial role in the clinical management of severe-profoundly deaf patients having bilateral absent or destroyed cochlea. Leveraging identical speech processor and receiver-stimulator such as the ones used in cochlear implants, stimulation of these electrodes can generate electrode-specific auditory sensations that generally remain stable for many years. Clinical evidence suggests that surface stimulation of human cochlear nucleus can offer a level of electrode-specific pitch cues that are very important for sound awareness and differentiation of environmental sounds. Over the recent years, selection and eligibility criteria for ABI patients has expanded significantly and now includes non-NF2 patients with anatomical constraints such as temporal bone fracture, cochlear ossification, and congenital malformations. This is further boosting adoption of auditory brainstem implants and is expected to continue to drive market growth over the forecast period.

Development of auditory brainstem implants that incorporate microelectrodes and can penetrate the cochlear nucleus to take advantage of cochleotopic organization in order to provide enhanced electrode-specific pitch perception is leading to increasing number of clinical trials to test safety and efficacy of these devices. ABIs have been proven to be extremely beneficial for non-NF2 patients and with benefits and safety observed in the adult patients, increasing number of clinical trials for testing ABIs in children have been underway across the globe and these are some other key factors expected to drive market growth over the forecast period.
Drivers: Technological advancements in auditory brainstem implants is key revenue growth driving factor
Auditory brainstem implant is majorly used for people who are born with no functioning auditory nerve or are deaf due to unusually shaped cochlea. Auditory brainstem implant consists of an external ear-level worn device and internal receiver-stimulator implant. The internal system comprises a surgically placed receiver-stimulator and magnet. Constant technological advancements in the field is leading to development of removable magnet that can be replaced with metallic non-magnetic spacer in patients who require frequent MRI scans. Upgrades in external speech processor and receiver-stimulator technology is needed to evoke enhanced auditory sensations and improved environmental sounds differentiation. In addition, pediatric patients implanted with ABIs have registered enhanced surgical and audiometric outcomes and improved communication abilities. These key factors are expected to significantly boost demand for auditory brainstem implants and drive market growth over the forecast period.
Restraints: High costs associated with auditory brainstem implants is a key factor restraining market growth
High costs of auditory brainstem implants and lack of awareness about these implants is resulting in lower adoption of the product, particularly in developing and underdeveloped countries. In addition, unavailability of standard care and skilled professionals are factors that could restrain market growth to a certain extent over the forecast period. Increasing incidence of complications such as cerebrospinal fluid leaks, wound infections, incomplete tumor removal, facial nerve weakness, and no benefit of ABIs in certain patients are some other key factors that could hamper market growth to some extent going ahead.
Medical Condition Outlook:
Based on medical condition, the global auditory brainstem implants market has been segmented into major cochlear malformation, complete cochlear ossification, fracture of the petrous pyramid, axonal neuropathy, auditory nerve tumors, and complete obliteration of both auditory nerves. Major cochlear malformation segment is expected to register robust revenue growth rate over the forecast period owing to auditory brainstem implants being the acceptable and effective treatment modality for patients with severe inner ear malformations. Use of auditory brainstem implants in patients revolutionized rehabilitation in adult and pediatric patients in whom cochlear implant surgery has been contraindicated due to cochlear, labyrinthine, or cochlear nerve aplasia.
Malformations can range from subtle defects in cochlear chamber partitions to complete absence of the inner ear. These malformations are a result of a defect in development and generally occur in the first trimester of the pregnancy – during the formation of membranous labyrinth. Auditory brainstem implantation is considered when CI is contraindicated or fails to offer adequate benefits to the patients. ABI can provide better outcomes and confers significant improvement in some cognitive parameters that are related to selective visual or spatial attention. ABI with surface electrodes can also provide sufficient stimulation of the central auditory system in adults and pediatrics for open set speech recognition, which is further boosting use of ABIs in children with profound hearing loss and are not eligible for cochlear implants.
Age Group Outlook:
Based on age group, the global auditory brainstem implant market has been segmented into adult and pediatric. Pediatric segment is expected to account for largest revenue share in the global market over the forecast period attributable to increasing auditory brainstem implantation surgery due to rising incidence of congenital profound hearing loss with anomalies such as cochlear, labyrinthine, and cochlear nerve aplasia in children across the globe. Profound hearing loss is the most common congenital and acquired sensory defect in children. Auditory brainstem implant surgery has proven to be extremely beneficial for a small subset of pediatric patients with severe to profound Sensorineural Hearing Loss (SNHL) that are ineligible for CI surgery due to absence of cochlear or auditory nerve or scarring of the inner ear caused by infection or trauma.
Advancements in auditory brainstem implantation surgery has made it a safe and effective option for stimulating the auditory cortex in children suffering from profound retro-cochlear deafness. Intense audio and verbal therapy and habilitation after ABI surgery also gives out better post-operative outcomes in majority patients. Over the recent past, initiatives are been taken to make this sophisticated technology the standard of care for hearing restoration in children suffering from severe inner ear malformations and this is expected to further boost revenue growth of the market going ahead.
Based on end-use, the global auditory brainstem implantation market has been segmented into hospitals, ENT clinics, and ambulatory centers. Hospital segment is expected to register significantly high revenue CAGR over the forecast period attributable to increasing availability and accessibility to advanced healthcare facilities and medical equipment, availability of skilled professionals, improved post-operative facilities, and increasing adoption of advanced diagnostic equipment and surgical services to treat congenital and acquired sensory deficits. In addition, growing network of dedicated hospitals that only offer surgical and medical treatments related to conditions of ears, nose, and throat and provision of cost-effective and affordable treatment options are some other factors expected to support revenue growth of the segment.
Based on the regional analysis, North America is expected to account for largest revenue share over the forecast period attributable to increasing incidence of sensorineural hearing loss among children and adults in the United States, rapid advancements in treatment of profound hearing loss in patients with inner ear abnormalities, and presence of well-developed healthcare infrastructure. According to current statistical analysis, about 13% of population in the United States – including people aged 12 years and older – have hearing loss in both ears and about 2% of adults have disabling hearing loss. This is expected to further boost demand for cochlear implantation and auditory brain implantation surgeries to better treat hearing loss and congenital ear defects. In addition, increasing investment to accelerate development of advanced devices to manage hearing loss, rising number of clinical trials to understand the efficacy of ABIs in improving hearing in children, and presence of key players in the region are some other key factors expected to drive market growth in the region.
