ABSTRACT
OBJECTIVE:
To assess outcomes of a new Osseointegrated Steady State Implant (OSSI) for bone conduction in adolescents.METHOD:
In an initial trial, 14 adolescents (14.5âyears of age, SDâ=â2.22) were provided with an OSSI; unilateral OSSI (nâ=â13), bilateral OSSI in sequential surgeries (nâ=â1). Outcomes measured were surgical duration, complications, hearing thresholds, speech perception and self-reported hearing benefits using the Speech and Spatial Quality of Hearing Questionnaire.RESULTS:
The surgical times were mean 93.6âminutes (SDâ=â33.3). Surgery was slightly longer in three adolescents who required skin flap reduction (nâ=â1) or significant bone polishing (nâ=â2) (121.33âminutes, SDâ=â8.14). Adverse events occurred in two adolescents post-implant poor external device retention in one child requiring revision flap reduction and inflammation at the incision site due to magnet overuse in another. The "Digital Link Calibration" measure was a good proxy predictor of the strength of magnet required for external device adherence (pâ=â0.002). The OSSI increased audibility in the implanted ear by mean 31.48âdB HL (SEâ=â1.58). Aided thresholds were best at 1âkHz (mean 25.33âdB HL, SDâ=â22.60) and only slightly poorer at 3000 and 4000âHz (estimate decreaseâ=â8.33âdB HL, SEâ=â3.54), reflecting good auditory sensitivity even at high frequencies. Speech perception when using the new device alone was good (89.67%, SDâ=â7.84%) and self-reported hearing by participants and parents improved in all domains assessed by the Speech and Spatial Quality of Hearing Questionnaire (estimateâ=â1.90 points, SEâ=â0.25, pâ<â0.0001).CONCLUSION:
The OSSI provides hearing benefits with surgical safety in a carefully selected cohort of adolescents.
