First experiences with a new adhesive bone conduction hearing device in children

Abstract

ObjectivesTo evaluate the hearing benefit, advantages, and disadvantages in a series of children using a new, nonimplantable, pressure-free, adhesive bone conduction hearing aid. MethodsSeventeen children were included in the study. 5 children suffered from bilateral conductive hearing loss (CHL), 6 children with unilateral CHL and 6 children with unilateral sensorineural hearing loss. An audiological tests were provide. Additionally, sound quality (SSQ10) and quality of life (AQoL-6D) were assessed using questionnaires. ResultsThe average value of speech audiometry with bubble noise in children with SNHL is 21.33 (±5.72) dB HL with the device and 27.67 (±4.59) dB HL without the device, which is a statistically significant gain (p = 0.027). The analysis showed the average value of hearing threshold in sound field in the group of children with CHL supported 20.23 (±16.84) dB HL and not supported 33.52 (±27.27) by the hearing aid for bone conduction, which i a statistically significant gain (p = 0.008). The average value of speech audiometry is 23.45 (±14.45) dB HL with the device and 37.27 (±26.65) dB HL without the device, which is a statistically significant gain (p = 0.012). The average value of speech audiometry with bubble noise is 30.55 (±10.03) dB HL with the device and 45.45 (±18.41) dB HL without the device, which is a statistically significant gain (p = 0.008). No patient referred pain or irritation. ConclusionThis new device for bone conduction show a hearing benefit for a paediatric patient, without any concomitant aesthetic and other complications.
