3.3 Audiological cochlear implantation outcomes
All four patients had bilateral profound HI. Early intervention with
hearing aids was provided, but poor hearing was observed in all
patients(Figure 2). Averaged auditory speech scores were rather low,
Categories of Auditory Performance (CAP) = 1.5 , speech intelligibility
rating (SIR) = 1.5, The (Infant Toddler)-Meaningful Auditory Integration
Scale (IT-MAIS)= 8.25, Meaningful Use of Speech Scale (MUSS)=6.5 before
surgery. Postoperatively, all patients received regular aural
rehabilitation. CAP, SIR, IT-MIAS and MUSS scores were assessed to
determine auditory and speech performances, which revealed improvements
in all patients. Case 2 showed most satisfactory improvement (Figure 2).
However, regarding SIR, and MUSS, cases 1, 3 and 4 showed relatively low
scores even at almost 5 years after the surgery.
