Objectives: This study aims to synthesize current knowledge and outcomes related to pediatric auditory brainstem implantation (ABI) in children with severe inner ear malformations (IEMs). It highlights the clinical management practices, challenges, and potential future directions for consensus development in this field., Methods: A systematic review of findings presented at the Third International Pediatric ABI Symposium organized by the Hacettepe Cochlear Implant team between 3 and 5 September 2020 was conducted, incorporating data from 41 departments across 19 countries. Relevant clinical outcomes, imaging techniques, surgical approaches, and rehabilitation strategies were analyzed to identify key trends and variability in practices., Results: The review indicates that children receiving ABIs exhibit diverse auditory outcomes influenced by individual anatomical variations and developmental factors. Early implantation, particularly before the age of three, positively correlates with better auditory and language development. Multicenter experiences underscore the necessity of tailored decision-making, which considers both surgical candidacy and comprehensive rehabilitation resources., Discussion:: The variability in outcomes emphasizes the need for improved consensus and guidelines regarding eligibility, surgical techniques, and multidisciplinary rehabilitation approaches. Notable complications and the necessity for thorough imaging assessments were also identified as critical components affecting clinical decisions., Conclusion: A formal consensus statement is warranted to standardize best practices in ABI management. This will not only enhance patient outcomes but also guide future research efforts to address the remaining challenges in the treatment of children with severe IEMs. Enhanced collaboration among team members will be pivotal in achieving these objectives.

Objectives: The aim of this study is to develop the Turkish version of hearing in noise test for children (HINT-C) by providing norms and correction factors for the children in different age groups. Methods: A total of 77 individuals with normal hearing - 62 children (6-12 years old) and 15 adults (18-30 years old) - were included. Twelve phonemically balanced 10-sentence lists were created from the adult version of the Turkish HINT (Study 1). Age-specific norms, correction factors and maturation effects were examined using the Turkish HINT-C (Study 2). Results: Mean performances under different listening conditions and Spatial Release from Masking (SRM) advantage values were obtained for the 6-, 8-, 10-, and 12-year-old and estimated for the 7-, 9-, and 11-year-old age groups, and correction factors were calculated for all children age groups. Turkish-speaking children did not achieve adult-like hearing in noise performance, until they were 12 years old. Conclusions: Twelve phonemically balanced 10-sentence lists of Turkish HINT-C were created, and the mean performances of children in different age groups were measured. In addition to the age-specific HINT-C norms and correction factors for the 6-, 8-, 10-, and 12-year-old age groups, the maturation effects were determined. Highlights The assessment of speech-in-noise perception is highly critical for children.To evaluate the speech-in-noise perception ability, 12 phonemically balanced 10-sentence lists of Turkish HINT-C were created.Speech-in-noise perception ability improves with age.Turkish-speaking children do not achieve adult-like hearing in noise performance, until they were 12 years old.

Objectives: The aims of this study were to collect data on electrically evoked compound action potential (eCAP) and electrically evoked stapedius reflex thresholds (eSRT) in HiResolution(TM) cochlear implant (CI) users, and to explore the relationships between these objective measures and behavioural measures of comfort levels (M-levels)., Methods: A prospective study on newly implanted subjects was designed. The eCAP was measured intra-operatively and at first fitting through neural response imaging (NRI), using the SoundWave(TM) fitting software. The eSRT was measured intra-operatively by visual monitoring of the stapes, using both single-electrode stimulation and speech bursts (four electrodes stimulated at the same time). Measures of M-levels were performed according to standard clinical practice and collected at first fitting, 3 and 6 months of CI use., Results: One hundred seventeen subjects from 14 centres, all implanted unilaterally with a HiResolution CII Bionic Ear(®) or HiRes 90K(®), were included in the study. Speech burst stimulation elicited a significantly higher eSRT success rate than single-electrode stimulation, 84 vs. 64% respectively. The NRI success rate was 81% intra-operatively, significantly increasing to 96% after 6 months. Fitting guidelines were defined on the basis of a single NRI measurement. Correlations, analysis of variance, and multiple regression analysis were applied to generate a predictive model for the M-levels., Discussion: Useful insights were produced into the behaviour of objective measures according to time, electrode location, and fitting parameters. They may usefully assist in programming the CI when no reliable feedback is obtained through standard behavioural procedures.
