Contraindications to cochlear implantation
Time:2010/7/14  Views:1200

    Contraindications to cochlear implantation may include deafness due to lesions of the eighth cranial nerve or brain stem. In addition, chronic infections of the middle ear and mastoid cavity or tympanic membrane perforation can be contraindications. The absence of cochlear development as demonstrated on CT scans remains an absolute contraindication. Certain medical conditions that preclude cochlear implant surgery (eg, specific hematologic, pulmonary, and cardiac conditions) also may be contraindications. The lack of realistic expectations regarding the benefits of cochlear implantation and/or a lack of strong desire to develop enhanced oral communication skills poses a strong contraindication for implant surgery.
