Intra-operative skull X-ray for misdirection of the cochlear implant array into the vestibular labyrinth. Sep 1st 2015, 11:06, by Hassan AM, Patel R, Redleaf M Related Articles Intra-operative skull X-ray for misdirection of the cochlear implant array into the vestibular labyrinth. J Laryngol Otol. 2015 Sep;129(9):923-7 Authors: Hassan AM, Patel R, Redleaf M Abstract OBJECTIVES: This paper reports five cases of aberrant cochlear implant electrode array insertion into the vestibular labyrinth. A review of the literature was conducted in order to clarify reasonable preventive and detection strategies and endorse the routine use of intra-operative plain skull X-ray. METHODS: The study entailed a clinical case series and literature review. The setting was a tertiary academic referral centre. The following data were evaluated: pre-operative temporal bone computed tomography, operative reports, intra-operative imaging, neural response telemetry/imaging and post-operative imaging. RESULTS: There were no consistent pre-operative risk factors found on computed tomography scans and no reliable intra-operative signs of electrode array misdirection. All misdirections in our case series, and those in the literature, were easily detectable on intra-operative plain film X-ray. CONCLUSION: These reported cases demonstrate implant misdirection without the surgeon's awareness. Aberrant insertion cannot be anticipated, and neural response telemetry/imaging is not a reliable indicator of misdirection. Routine intra-operative anteroposterior plain X-ray of the head is a reliable indicator of misdirection, and is fast and relatively inexpensive. PMID: 26314324 [PubMed - in process]
