Current trends in outcome studies for children with hearing loss and the need to establish a comprehensive framework of measuring outcomes in children with hearing loss in China

Active TriCROS: A Simultaneous Stimulation With a (Bi)CROS System and a Hearing Aid in the Worst Ear for Severely Asymmetrical Hearing Loss

OBJECTIVE

Severely asymmetrical hearing loss (SAHL) is characterized by a moderately severe or severe hearing loss in one side and normal or mildly impaired controlateral hearing in the other. The Active tri-CROS combines the Contralateral Routing-of-Signal System (CROS, or BiCROS if the best ear is stimulated) and the stimulation of the worst ear by an in-the-canal hearing aid. This study aims to evaluate the benefit of the Active tri-CROS for SAHL patients.

STUDY DESIGN

This retrospective study was conducted from September 2019 to December 2020.

SETTING

Ambulatory, tertiary care.

PATIENTS

Patients were retrospectively included if they had received the Active tri-CROS system after having used a CROS or BiCROS system for SAHL for at least 3 years.

MAIN OUTCOME MEASURES

Audiometric gain, signal-to-noise ratio, spatial localization, and the Abbreviated Profile of Hearing Aid Benefit and Tinnitus Handicap Inventory questionnaires were performed before equipment and after a month with the system.

RESULTS

Twenty patients (mean, 62 yr old) with a mean of 74.3 ± 8.7 dB HL on the worst ear were included. The mean tonal hearing gain on the worst ear was 20 ± 6 dB. Signal-to-noise ratio significantly rose from 1.43 ± 3.9 to 0.16 ± 3.4 dB ( p = 0.0001). Spatial localization was not significantly improved. The mean Tinnitus Handicap Inventory test score of the eight patients suffering from tinnitus rose from 45.5 ± 18.5 to 31 ± 25.2 ( p = 0.016).

CONCLUSIONS

The Active tri-CROS system is a promising new therapeutically solution for SAHL.

French adaptation and validation of parents' evaluation of aural/oral performance of children (PEACH) scale in children

OBJECTIVE

Hearing loss can seriously impact children's quality of life. Disease-specific questionnaires are required to optimise medical care. This study aims to translate, adapt and validate the French version of the PEACH score for the auditory performance of children.

DESIGN

This is a controlled, prospective study, conducted between April and October 2020. The translation was conducted using a forward-backward technique, and statistical validation was conducted with a test and re-test, on a patient population and a control population.

STUDY SAMPLE

Patients were included if they were 1-11 years old, and had at least 30 dB hearing loss in one ear. The mean age was 6 years for the 39 patients and 3.9 years for the 34 controls.

RESULTS

Reproducibility, measured by Spearman's coefficient between global scores of the test and re-test was 0.78 (p < 0.001). The test was internally consistent (Cronbach's alpha was 0.89) and item per item construct validity was satisfactory. The ROC curve showed a moderate area under the curve (0.74 p < 0.001) with 67% sensitivity and 73% specificity.

CONCLUSIONS

The French PEACH had good statistical properties, although a brief 13-item questionnaire, and can be used for evaluation of the disease-specific quality of life for young children with hearing loss.

The Potential Use of P1 CAEP as a Biomarker for Assessing Central Auditory Pathway Maturation in Hearing loss and Associated Disabilities: a case report

We report a case in which we quantified the maturation of the central auditory pathway in children with hearing loss and associated disabilities; the audiological intervention was performed using the BAHA softband. The hearing aid was applied according to the international clinical protocols. The presented case reveals the importance of using the P1 CAEP biomarker in clinical practice along with a neuropsychological evaluation to assess the maturation of the central auditory pathways and to objectively quantify the results of auditory rehabilitation in children with hearing loss and associated disabilities.
