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 Oct;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

S E J Connor

Clin Radiol 2018 Jan 5;73(1):19-34. Epub 2017 Apr 5.

Neuroradiology Department, King's College Hospital, London, UK; Radiology Department, Guy's and St Thomas' Hospital, London, UK. Electronic address:

There have been significant advances in the diversity and effectiveness of hearing technologies in recent years. Implanted auditory devices may be divided into those that stimulate the cochlear hair cells (bone conduction devices and middle ear implants), and those that stimulate the neural structures (cochlear implants and central auditory implants). Contemporary preoperative and postoperative imaging may be used to help individualise implant selection, optimise surgical technique and predict auditory outcome. Read More
