Early experience on a modern, thin cochlear implant family. A retrospective, international multicenter study.

J Med Life 2018 Apr-Jun;11(2):146-152

University of Szeged, Albert Szent-Györgyi Clinical Center, Department of Otorhinolaryngology, Head and Neck Surgery, Szeged.

Rationale: Cochlear implantation is the most effective method of rehabilitation for patients with severe to profound sensorineural hearing loss. Binaural hearing forms the basis of the development of hearing-associated cortical networks in infants and toddlers, but simultaneous bilateral implantation is often postponed due to the demands of classical surgical methods, which are associated with large incisions and a deep bony well.

Objective: The authors report on the use of a modern, thin implant type and the possibilities it provided to simplify the surgical technique. Read More

Assessing Cochlear Length Using Cone Beam Computed Tomography in Adults With Cochlear Implants.

Otol Neurotol 2018 10;39(9):e757-e764

Department of Otolaryngology, Westmead Hospital, University of Sydney, Sydney, Australia.

: Developing a clinically viable technique for measuring cochlear length could enhance future electrode design of cochlear implants and surgical skills to improve clinical outcomes. While computed tomography (CT) has been used, metal artifact and the exposure to higher levels of radiation limits its use. More recently, cone beam CT (CBCT) has been used to assess the integrity of the implant array in situ, exposing implantees to lower levels of radiation while retaining image quality. Read More

Otol Neurotol 2018 10;39(9):1109-1114

UCLH/UCL Auditory Implant Programme, Royal National Throat Nose & Ear Hospital, London, UK.

Objective: Preserving low frequencies following cochlear implantation improves outcomes and allows patients to use a combination of electrical and acoustic stimulation. This importance has been reflected in advances in electrode design and refined surgical techniques. Full insertion of standard length electrodes may be advantageous over shortened electrodes because more electrodes can be activated over time if low frequency hearing loss progresses. Read More
