Inner ear disorders are a common group of diseases that manifest as hearing loss, tinnitus and vertigo. Especially, hearing loss in both ears can lead to lifelong disability, which not only causes great pain to patients, but also increases the burden of families and society. However, there are many causes of hearing loss, tinnitus and vertigo, which involve a wide range of disciplines and are difficult to diagnose and treat. Sensorineural deafness includes both sensorineural and postcochlear lesions, which must be localized through a series of audiological tests and imaging examinations to identify cochlear and postcochlear lesions. Depending on the disease, different treatment methods are adopted, ranging from prevention, medication, surgery and rehabilitation with the help of instruments. For example, early diagnosis and prevention of vestibular conduction duct syndrome, early drug treatment of sudden deafness, and so on, will not be described here; mainly, the following rehabilitation methods are available for patients who cannot be treated etiologically or who have progressed to advanced severe cochlear deafness and partial postcochlear deafness through prevention and drug treatment. The middle ear implantable hearing aid, also known as the artificial middle ear, is a hearing aid device that is implanted in the middle ear and replaces the function of the middle ear. As defined by the First Annual International Conference on Otologic Implants held in Florida, the artificial middle ear is a device that is surgically implanted to cause the auditory chain or its appendages to vibrate. In the past 20 years, in-depth research has been conducted on this topic mainly in Japan, the United States and Germany, and in recent years, a few hospitals in China have conducted research. The basic components of middle ear implantable hearing aids include external wear device: sound processor, called Audio processor (AP): including microphone, sound processor, magnet, microphone, high energy battery; internal implant device: artificial vibrating auditory bone implant. It includes a magnet wound with a receiver coil, a case, a conductor connection wire and an implanted oscillator (FMT). Root indications are moderate to severe hearing loss, including sensorineural deafness, conductive deafness or mixed deafness are possible, speech recognition rate ≥ 50%, and those who are unwilling or unable to wear hearing aids for a long time. The effect can be improved at different frequencies when compared with conventional hearing aids, and reports vary. Luetje compared patients with VSB implants after 3 months with patients with conventional hearing aids and came to the following conclusions: patients with VSB-P models showed satisfactory hearing improvement at all frequencies, with hearing thresholds up to 10 dB in the 2 to 6 KHz band, and between 2 and 6 KHz, both clinical The hearing threshold can reach 10 dB in the 2-6 KHz range, and between 2 and 6 KHz, which is significantly better than conventional hearing aids in both clinical tests and patients’ active perception. Some scholars believe that the implantation of VSBs does not have a significant effect on the hearing test results of patients, and even slightly decreases the hearing test results of some patients who were wearing traditional hearing aids. There was also no significant improvement in speech recognition in a quiet environment, but communication in various listening environments, such as talking to familiar people and listening in background noise, showed a significant improvement in speech recognition, and the distortion of speech was better than the original hearing aid; and they could use it all day long without pain and itching. On the other hand it is also related to the type of processor AP, the speech recognition rate in a noisy environment is significantly better with Signia than with VSB-D. Compared to hearing aids there is also a non-existent sense of blockage, whistling and feedback are greatly reduced, the part behind the ear can be covered by hair without affecting the aesthetics, and maintenance problems caused by cerumen and moisture are greatly reduced. Potential disadvantages and problems are mainly the cost is more expensive, generally between $10,000 and $20,000, non-disposable, requires multiple visits, requires experienced doctors and audiologists to provide such services, currently the implant cannot be reprogrammed to adjust electroacoustic parameters through the patient’s subjective wishes, AP and FMT still have a lot of room for further research, implantable hearing aids can have surgical and anesthetic complications There is a possibility of surgical and anesthetic complications with implantable hearing aids, such as damage to the facial nerve and auditory chain, touching the stapes resulting in high frequency drop, etc. In addition, implantable hearing aids are not compatible with MRI. Early implantation oscillators were mostly connected to the long foot of the auditory and anvil bones and used the traditional sound conduction pathway to transmit sound into the inner ear through the oval window, requiring patients with normal middle ear function in patients with sensorineural deafness, and nowadays, transcircular window bridge (VSB) implants are also available, and middle ear implants are feasible even in patients with conductive deafness or mixed deafness who have severe auditory chain deformities or failed auditory chainplasty procedures.Colletti V et al [1] achieved success in seven patients with severe mixed deafness (six with multiple auditory chain malformations and one with unsuccessful VSB implantation on the anvil) by implanting a vibrating transducer on the round window to transmit sound directly into the inner ear. The postoperative hearing threshold was reduced from 60-80 dB to 30 dB in the bare ear; 50% speech intelligibility was 50 dBHL; and most patients achieved 100% intelligibility at the conversational level, compared to 80 dBHL and 100% intelligibility at the conversational level in only one case, respectively. The cochlear implant is a surgically implanted internal part (including the shell, reference electrode and stimulation electrode), in which the shell is embedded in the temporal side of the skull and the stimulation electrode is implanted at the tympanic level. The electrode stimulates the patient’s auditory nerve endings with a small but safe current, thus responding to the sound waves generated by the microphone (external part). The indications for cochlear implantation (FDA) were gradually expanded and in 2000 the indications were prelingual and postlingual deafness in adults or children (12 months), severe – profound deafness: ≥ 2 years, profound deafness: < 2 years, and ear implantation.
