Purpose: Simultaneous bilateral cochlear implantation is often seen as the gold-standard intervention for many people with bilateral deafness. However, this intervention is not as commonly performed in China. This paper presents the surgical technique and the peri- and postoperative safety results from simultaneous bilateral implantation and compares them with those from sequential bilateral implantation.
Methods: Twenty nine children (aged 12‒18 months) met the inclusion/exclusion criteria and took part in this study. 10 participants received a unilateral cochlear implantation; 19 participants received simultaneous bilateral cochlear implantation. The same standard surgical technique (transmastoid facial recess approach with round window insertion) was used in all implantations. Safety was assessed via monitoring peri- and postoperative adverse events. The helpfulness of select surgical tools was assessed via questionnaire.
Results: No adverse events were reported for any participants. All queried surgical tools were helpful in all 244 recorded responses.
Conclusion: Simultaneous bilateral cochlear implantation can be performed using the same surgical technique as unilateral implantation and poses no increased safety risk for children aged 1‒2 years.
