Epicutaneous patch test—A new diagnostic option to prevent the rejection of silicone-covered cochlear implants in children

Abstract Objectives Cochlear implantation (CI) is a revolutionary method for hearing rehabilitation in patients with severe or profound sensorineural hearing loss. One of the surgical complications may be the necrosis of the skin flap above the receiver-stimulator coil, resulting in device extrusion...

Description
Summary:Abstract Objectives Cochlear implantation (CI) is a revolutionary method for hearing rehabilitation in patients with severe or profound sensorineural hearing loss. One of the surgical complications may be the necrosis of the skin flap above the receiver-stimulator coil, resulting in device extrusion. Our aim was to find the plausible causes of the silicone covered implant rejection. Patients and methods Authors present four cases of cochlear implant rejection, briefly describe their dermato-surgical solutions and analyse their innovative method – the epicutanoeus patch testing with silicone samples. Results They observed positive skin reaction in three of the four cases. Conclusion Authors analyse the applicability and results of their surgical solutions and the epicutaneous testing in connection with the prevention of skin flap necrosis and rejection of silicone-covered cochlear implants.
