Abstract:ObjectiveTo analyze the causes, treatment and prognosis of cochlear reimplantation in 23 pediatric patients.MethodsClinical data of 23 children underwent cochlear reimplantation in our center from September 2013 to June 2019 were reviewed. The reasons, treatment and prognosis of reimplantation were analyzed.ResultsCauses of the reimplantation included trauma (1 case), poor fixation of electrodes (1 case), infection in the surgical field (5 cases), poor hearing aid not resulted from wrong speech processor, surgery nor patients themselves (2 cases), unexplained implant failure (14 cases). In the 5 patients with infection, twostage reimplantation was performed after removal of implant device and control of infection. Of them, 2 underwent ipsilateral reimplantation and 3 underwent contralateral reimplantation. All the 23 patients received primary unilaterally implantation in the right ear. In the twostage surgery, bilateral cochlear reimplantation was performed in 2 cases and contralateral reimplantation in 3. All the patients were followed up for one month to five years and ten months, and performed normal hearing by the cochlear system after reimplantation. During the followup period, dizziness occurred in one case with intraoperative gusher and got relieved within 3 days. Subscalp hematoma appeared in one and absorbed automatically within 2weeks.ConclusionsCauses of the reimplantation include trauma, intraoperative poor fixation of electrodes, infection, poor hearing aid effect, unexplained implant failure. Device failure and infection are the most common causes. Cochlear reimplantation will neither increase incidence of complication nor affect surgical outcomes. To reduce the risk of reimplantation, accurate and minimally invasive cochlear implantation should be advocated to reduce surgical complications and the reinforcement of education for patients’ family is also necessary to reduce the risk of trauma.
