Adult Cochlear Implantation Under Local Anesthesia and Conscious Sedation with Dexmedetomidine: Efficacy and a Method to Interact with the Conscious and Cooperative Patient.

Background: This study describes the efficacy of cochlear implantation under local anesthesia with conscious sedation with dexmedetomi- dine in adult patients and proposes a method to communicate with the conscious and cooperative patient intraoperatively. This less invasive anesthetic procedure is suitable for patients with comorbidities preventing general anesthesia.

Methods: Unilateral cochlear implantation with Oticon Medical systems was performed in 10 adult patients with comorbidities preventing general anesthesia.

Spontaneous bone bed formation in pediatric cochlear implantation is associated with duration of implantation.

Objectives: This study investigated the long-term postoperative spontaneous formation of a bone bed in pediatric cochlear implant patients for whom no bone bed was drilled during the surgery.

Methods: A cross-sectional observational study of skull thickness under and on the edges of the cochlear implant receiver/stimulator in children with computed tomography (CT scan) ≥6 months after implantation was performed. In total, 37 pediatric patients from a single tertiary center underwent cochlear implantation without bone bed drilling and with screw fixation of the receiver/stimulator.
