Complications in a series of 4400 paediatric cochlear implantation.

Objectives: The purpose of this study is to retrospectively review the complications of paediatric patients undergoing cochlear implantation at four major Iranian cochlear implant centres.

Methods: A retrospective analysis was performed of all patients who underwent primary cochlear implantation from January 1991 to December 2013. The patients were reviewed for demographic information, and complications including cerebrospinal fluid leak, meningitis, facial palsy, and wound infection.

Determining compliance of ear CT scan with interaoperative findings in deaf children with cochlear implantation.

Introduction: Defecated or impaired hair cell function of the cochlea causes deafness. Cochlear implantation allows transmission of sound information through central auditory pathways using direct electric stimulation of auditory nerve dendrites. Using radiologic imaging, including CT scan is very helpful in selection of candidates and evaluation after implantation.
