موضوع انگلیسی:The rationale for FLEX (cochlear implant)
electrode with varying array lengths
بخشی از متن:With cochlear implantation (CI) being the standard of care for profoundly deaf
cases, more and more patients with low frequency residual hearing are currently being treated
with CI. In view of preserving the residual hearing, the ultimate aim of both the surgeons and
the CI companies is to achieve zero-degree of electrode insertion trauma. Variations in the size
and shape of cochlea, cross-sectional dimensions of ST, electrode insertion techniques with
and without metal stylet rod and the experience level of the operating surgeons, all play a role
in the electrode array related insertion trauma. An effective electrode design must include
flexible array to accommodate the cochlear shape variation, electrode with variety of array
lengths to support the concept of cochlear size specific electrode array and finally smaller
cross-sectional dimensions of electrode array in matching the cross-sectional dimensions of
ST. As per published reports, FLEX electrode array design offers minimal degree of electrode
insertion trauma along with the possibility of patient specific electrode array length matching
their cochlear size. Looking at the cross-sectional dimensions of FLEX electrode array along
with its volume, it appear to be highly safe to the cochlea by not taking too much volume inside
the ST. To offer additional support, otological pre-planning software tool like OTOPLAN is now
clinically available in measuring the cochlear size in finding the best electrode array match
along with the possibilities of anatomy based post-operative speech processor fitting.
