Fig. 3From: Randomized placebo-controlled clinical trial investigating the effect of antioxidants and a vasodilator on overall safety and residual hearing preservation in cochlear implant patientsHearing loss 3 months after the first fitting in patient groups receiving either ACEMg or placebo, grouped for the implanted electrode length (Flex 20 (= 16 mm and 20 mm), Flex 24 or Flex 28) and being implanted by surgeon 2 or other surgeons. No difference between ACEMg and placebo was observed, but patients receiving shorter electrodes showed less loss of residual hearing than those being implanted with a longer arrayBack to article page
