Abstract:
: Cerebrospinal fluid (CSF) gusher encountered during cochlear implantation are most commonly encountered in the setting of an inner ear abnormality. Repair of the gusher is essential to prevent CSF egress postoperatively and to decrease the risk of meningitis. Various methods to repair a CSF gusher have been described, including tight packing of the cochleostomy with fascia, lumbar drainage, and Eustachian tube packing with ear canal overclosure. We describe a novel and simple technique using a fascia ring placed around the cochlear implantation electrode (Cochlear Corporation, CI522) as a means to treat CSF gusher. The fascia is slid down the electrode after insertion, allowing circumferential coverage of the defect. The following video will provide an overview of patients at risk for CSF gusher and demonstrate the technique described above.SDC video link: http://links.lww.com/MAO/B52.
