[Minimally invasive surgical techniques of cochlear implantation withround window pathways in young children]

Objective:To discuss the minimally invasive surgical techniques and the effect of cochlear implantation with round window pathways in young children(≤3 years).Method:One hundred and sixty patients with bilateral profound sensorineural hearin loss received MED-EL cochlear implantation,including 144 cases of normal middle and inner ear,4 cases of Mondini deformity,12 cases of large vestibular aqueduct syndrome.Result:Of 160 patients underwent CIs,148 patients were performed with round window pathways,the rate was 92.5%. Iit's difficult to exposure round window in 12 patients,performing from promontory.All electrodes of 158 cases with unilateral CI and 2 cases with bilateral CI were implanted successfully,in which the CI went normally and electrode array were protected well.All implant devices had worked normally and all patients had performed well during an average follow-up period of 8 month-3 years.Post-operatively complications of cerebrospinal fluid leakage,facial nerve injury haven't been found.Conclusion:Cochlear implantation could be performed in patients wit with round window pathways,and it is a safe and effective way in young children.
