  • Title: Multichannel extracochlear implant.
    Author: Pulec JL, Smith JC, Lewis ML, Hortmann G.
    Journal: Am J Otol; 1989 Mar; 10(2):84-90. PubMed ID: 2525341.
    Abstract:
    The transcutaneous eight-channel extracochlear implant has undergone continuous revision to simplify the surgical technique, to minimize patient morbidity, and to improve performance. The extracochlear electrode array has been miniaturized so that it can be inserted through the facial recess without disturbing the external auditory canal, tympanic membrane, or malleus. The use of the remote antenna placed around the external auditory canal has greatly increased battery life and patient comfort. With its simplified incisions, the surgical procedure can be performed as out-patient surgery. Preoperative cochlear nerve testing and use of evoked response cochlear nerve testing allow preadjustment of the speech processor. Current features and performance of the implant are discussed.
