Silicone allergy can lead to cochlear implant complication and explantation: a case report

Although rare, it's important to be aware of delayed hypersensitivity reactions to the silicone component of a cochlear implant. Attention should be made to associate symptoms such as pruritis, urticaria and loss of hair as symptoms and signs of possible allergic reaction to the implanted component. Steroids may help to alleviate symptoms; however, symptoms have been shown to recur after cessation of steroids. Treatment requires the removal of the device.
