Other types of deafness that are not suitable for otological surgery, such as: the CT/MRI scan found that there were middle inner ear dysplasia or malformations, vestibular cochlear nerve abnormalities caused deafness, conductive deafness, mixed deafness, and malformation syndrome; 9. Preexisting ear diseases may hinder the planned surgery or interfere with the interpretation of research endpoints, such as acute chronic otitis media, Meniere's disease, acoustic neuroma, sudden deafness, and unrecovered hearing; 10. Have a history of drug abuse, or have received any known ototoxicity drug treatment (such as aminoglycosides, cisplatin, loop diuretics, etc.) within 6 months, or have received antiviral and immunotherapy within 3 months, or have been vaccinated within 1 month; 11.
