Abstract
Unilateral aural atresia (UAA) is a congenital condition that is associated with maximal conductive hearing loss. The primary objective of this study was to assess the long-term compliance, complications, and quality of life of pediatric patients with UAA who had transcutaneous bone conduction hearing implants (TCBI). Retrospective consecutive case series at a single centre between 2014 and 2018. Inclusion criteria consisted of UAA patients between 5 to 17 years-old receiving the Cochlear Baha Attract ® device. Demographic and audiologic data was extracted from charts. A prospective telephone survey was done, with patients and their families completing the Glasgow Children's Benefit Inventory (GCBI). Basic descriptive statistics, paired t-tests, and a univariate analysis were completed. Data was successfully collected from all 9 eligible children who received the Cochlear Baha Attract ® device for UAA (100%). The mean follow-up duration was 33 months after TBCI (9-60 months). The mean daily use was 7.7h/day. Pure tone average and mean speech in noise scores were both significantly improved when comparing the unaided condition to the aided condition with TCBI (p<0.001). The majority (89%) of patients had an improvement in GCBI; the median GCBI score was +14.6, indicating overall positive benefit. A linear regression showed no demographic variables were significant for mean daily use or GCBI scores. This preliminary study showed that patients with a TCBI for UAA had high long-term compliance and daily usage rates. TCBI improved the quality of life for the majority of patients and significantly improved hearing measures.
