Background: Data on hearing and speech outcomes following cochlear implantation in prelingual sensorineural loss (SNHL) children with nerve hypoplasia, especially Indonesia, is still limited. Purpose: To evaluate the function of SNHL who had undergone implantation. Method: A retrospective cross-sectional study was conducted 28 procedures at Department Otorhinolaryngology Head Neck Surgery, Dr. Cipto Mangunkusumo National General Hospital, Jakarta, for more than 12 months. The subjects were assessed using modified Categories Auditory Performance (CAP-II) intelligibility rating (SIR) scores. Result: Children hypoplasia showed an increase CAP-II SIR scores after implants months (versus pre-surgery, high CAP score [≥5]: 89.3% [25/28 children] vs 3.6% [1/28 [≥3]: 82.1% [23/28 7.1% [2/28 children]; both p<0.001). Post-operative post-operative highly positively correlated (r=0.705, Type (unilateral bilateral) not significantly associated (p=0.382 p=0.459, respectively). Conclusion: Prelingual may get benefit from implantation, as shown by a remarkable improvement scores.
