Abstract:Cochlear implantation can help postlingually deafened adults regain auditory function and is currently one of the primary treatment methods for severe to profound sensorineural hearing loss. However, there is significant individual variability in postoperative rehabilitation outcomes. Currently, commonly used speech perception tests, categories of auditory performance, and speech intelligibility rating are used internationally to assess postoperative rehabilitation outcomes in postlingually deafened cochlear implant adults. Meanwhile, the Speech, Spatial, and Qualities of Hearing Scale (SSQ) and Quality of Life assessment scales can offer more comprehensive evaluation dimensions than previous methods. Previous research results indicate that preoperative intrinsic factors and postoperative intervention factors, especially the mapping scheme, are important influencing factors on the postoperative rehabilitation outcomes of postlingually deafened cochlear implant adults. With the development of society and incre
