Abstract Objective:

This study aimed to evaluate migration of the receiver–stimulator after cochlear implantation using the subperiosteal pocket technique.


A prospective clinical study was performed of 32 paediatric patients (aged between 12 months and 8 years; mean ± standard deviation, 28 ± 19 months) who underwent cochlear implantation in tertiary referral centres. The degree of migration was evaluated using measurements between the receiver–stimulator and selected reference points: the lateral canthus, tragus and mastoid tip. All distances were measured during and six months after surgery.


No receiver–stimulator migration was observed when using the subperiosteal pocket technique.


Concerns about implant migration in the subperiosteal pocket technique are unwarranted: this is a safe technique to use for cochlear implantation.
