The long-term effect of general anesthesia on developing brain is the focus of clinicians when infants exposed to general anesthesia for a long time during operation. A retrospective study showed that children exposed to long-term or repeated operations, the anesthetics had a higher incidence of cognitive impairment in adolescence than those did no. When infants with hearing impairment undergo bilateral cochlear implant surgery, they are at high risk of long-term neurobehavioral abnormalities caused by anesthesia. In this study, investigators intend to observe the long-term behavioral abnormalities of hearing-impaired infants after unilateral or bilateral cochlear implantation.
