Mini-Incision for Pediatric Cochlear Implantation with a MED-EL Device

OBJECTIVE: Minimal invasive approaches have been described for cochlear implantation. However, the number of reports about minimal invasive approaches for MED-EL devices is sparse. In this technical note, we describe our pediatric cochlear implantation and incision techniques for MED-EL devices. METHODS: Among 92 cochlear implantations performed between November 2002 and November 2006, there were 32 consecutive pediatric cochlear implantations with MED-EL devices which were performed between July 2005 and October 2006. In our technique, standard posterior tympanotomy and cochleostomy were performed after 4- to 5-cm mini-incisions in the postauricular region. However, suture fixations were not used for the implant receiver nor its electrode. RESULTS: There were 14 girls and 18 boys with a mean age of 3.9 years. The mean follow-up duration was 5.8 months. No flap necrosis, hematoma or infection, nor implant migration, extrusion or breakdown were encountered. Revision surgery was performed in 3 patients due to cochlear ossification, perilymph leakage and extracochlear implantation. CONCLUSION: MED-EL implantation can be performed using small incisions without suture fixation of the receiver and its electrode.
