Cochlear implant array insertion forces are potentially related to cochlear trauma. We compared these forces between a standard (Digisonic SP; Neurelec, Vallauris, France) and an array prototype (Neurelec) with a smaller diameter. The arrays were inserted by a mechatronic tool in 23 dissected human cochlea specimens exposing the basilar membrane. The array(More)
BACKGROUND The cerebral function monitor (CFM) is widely used to detect neonatal seizures, but there are very few studies comparing it with simultaneous electroencephalography (EEG). OBJECTIVE To determine the accuracy of non-expert use of the CFM and to assess interobserver agreement of CFM seizure detection. PATIENTS Babies admitted to the neonatal(More)
Transient deafness associated with an increase in core body temperature is a rare and puzzling disorder. Temperature-dependent deafness has been previously observed in patients suffering from auditory neuropathy. Auditory neuropathy is a clinical entity of sensorineural deafness characterized by absent auditory brainstem response and normal otoacoustic(More)
The aim of this study was to evaluate electrode array position in relation to cochlear anatomy and its influence on hearing performance in cochlear implantees. Twenty-two patients (25 ears) with Med-El cochlear implants were included in this retrospective study. A negative correlation was observed between electrode-modiolus distance (EMD) at the cochlear(More)
The tele-operated system with three arms for the microsurgery of the middle ear is composed of an operator console from where the surgeon tele-operates three robotized arms that hold surgery tools with a high level of accuracy. The main difference between these micromanipulators and the conventional minimal-invasive surgery robots is the increased field of(More)
AIM OF THE STUDY To review indications, anatomical results, and complications of cochlear implant (CI) surgery in adults for which middle ear and mastoid obliterations were performed. PATIENTS AND METHODS Thirty cases (26 patients, 4 bilaterally implanted) of 837 CI surgeries (3.5%) performed between January 2009 and December 2013 have been included in(More)
HYPOTHESIS The aim of the study was to evaluate force profiles during array insertion in human cochlea specimens and to evaluate a mechatronic inserter using a 1-axis force sensor. BACKGROUND Today, the surgical challenge in cochlear implantation is the preservation of the anatomic structures and the residual hearing. In routine practice, the electrode(More)
Computer-assisted navigation systems can now potentially guide the surgeon to the cochlea with a trajectory avoiding the facial nerve through a keyhole approach. Five temporal bone specimens, with 4 titanium screws placed in the mastoid cortex, were studied. Preoperative computed tomographic scan images were loaded on an electromagnetic computer-assisted(More)
