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.
