Standardization of CT depiction of cochlear implant insertion depth.
BACKGROUND AND PURPOSE Imaging a cochlear implant with CT is challenging because of implant-induced artifacts, anatomic cochlear variations, and lack of standard terminology for cochlear anatomy. The purposes of this project were to determine whether the cochlear implant tip was more accurately located on oblique CT reformations than on standard images, to review radiology reports for accurate ...
متن کاملInvestigating the Effect of Cochlear Size in Insertion of Electrode Depth in Patients with Cochlear Implantation evaluated by CT-Scan
Background Cochlear implant surgery is an invasive procedure for patients with bilateral Sensorineural hearing loss and may cause some risks such as cochlear damage. We aimed to evaluate the effectiveness of cochlear measures obtained by computed tomography (CT) scan in predicting depth of cochlear implant insertion. Materials and Methods This study was conducted in a retrospective and cross-se...
متن کاملUncertainty Quantification of Cochlear Implant Insertion from CT Images
Cochlear implants (CI) are used to treat severe hearing loss by surgically inserting an electrode array into the cochlea. Since current electrodes are designed with various insertion depth, ENT surgeons must choose the implant that will maximise the insertion depth without causing any trauma based on preoperative CT images. In this paper, we propose a novel framework for estimating the insertio...
متن کاملSimulating the effect of cochlear-implant electrode insertion depth on speech understanding.
Normally hearing listeners were presented with vowels, consonants, and sentences for identification through an acoustic simulation of a five-channel cochlear implant with electrodes separated by 4 mm (as in the Ineraid implant). The aim of the experiment was to simulate the effect of depth of electrode insertion on identification accuracy. Insertion depth was simulated by outputting sine waves ...
متن کاملThe Cochlear Implant
The studies on cochlear implants have been conducted in the United States, Austria, Brasil, France, Finland, and some other countries. Up to now, this technique does not seem to have a wide spread application. Indeed it can only apply cases of deafness still presenting sufficient neural remnants to transmit the message. Moreover, the patient must be totally deaf( quasi complete loss of har cel...
