Such problems bring rise to dead regions in the hearing organs which are not sensitive to any amplification or noise reduction strategies and hence causing the failure of implants. Speech recognition and thereby the intelligibility of the humans are those areas which fail to get activated with an implant because of these issues. There are research activities going on in these troublesome areas which when turning fruitful could do wonders in increasing the success rate of the implants. (Niparko 2009) The aforementioned are factors that influence the success of cochlear implants. However, there are some disadvantages as well like undergoing surgery, which could result in various other infections and health hazards. The FDA has data that shows most children who underwent surgery suffered from acute meningitis post-surgery. They concluded that these recipients have 30 times more probability of acquiring meningitis as compared to normal children. The cost involved for an implant is on the higher side which again not all can afford. Physically adorning the device could be very fastidious and extra precautions are required for it to function properly. If in case the device malfunctions, then the only way to correct it would be to undergo another surgery, which is a high-risk factor. The device needs to be maintained well and updated frequently to ensure smooth functioning. The Success of Cochlear implants.
