Summary: | Objectives
To demonstrate the feasibility and efficacy for next-day loading of a percutaneous bone-anchored hearing device.
Study Design
Multicenter prospective cohort study.
Setting
Tertiary neurotologic referral centers.
Subject and Methods
In this multicenter prospective study, a 4.5-mm laser-etched bone-anchored hearing device was implanted in adult subjects who had conductive/mixed hearing loss or single-sided deafness. One day following implantation, the surgical site was assessed for soft tissue reaction per the Holgers Scale, and implant stability was evaluated by manual palpation and resonance frequency analysis. On the same day, subjects were fitted with the processor. Follow-up evaluations were at 1 week, 4 weeks, 3 months, 6 months, and 12 months. The Glasgow Benefit Inventory and Abbreviated Profile of Hearing Aid Benefit questionnaires were completed postoperatively.
Results
Fourteen devices were implanted in 12 subjects. Two subjects underwent bilateral implantation. Implant stability was rated as firm at every interval for all ears, and the Implant Stability Quotient values at 3 months were stable or increased as compared with day 1 measurements. Skin irritation was limited to Holgers grade 0 and 1, with the majority having no skin irritation. The mean Glasgow Benefit Inventory global score was +43.8, and the mean Abbreviated Profile of Hearing Aid Benefit global benefit score was 60.2%. All 14 implants have remained firmly anchored.
Conclusions
Next-day loading of this 4.5-mm-diameter percutaneous bone-anchored hearing device appears to be a feasible alternative to the original 3-month delayed loading. Although this is a preliminary study, the results support continued investigation of a next-day loading strategy. |
