(A849) Predictive Accuracy of Softband Simulation for Postoperative Hearing with Bone Conduction Devices

Introduction: Bone conduction devices (BCDs) provide critical auditory rehabilitation for patients with conductive and mixed hearing loss or single-sided deafness when traditional hearing aids are unsuitable. Preoperative softband simulations are used to estimate postoperative outcomes, yet their predictive accuracy remains underexplored. Validating these simulations is essential to optimize patient counseling and align expectations with real clinical outcomes.

Methods: This retrospective paired-control study analyzed audiometric and patient-reported outcomes from individuals who underwent BCD implantation (Osia, Baha, Bonebridge, or Ponto). Preoperative softband simulation data, including hearing thresholds and speech perception scores, were compared to postoperative audiometric measures. Patient satisfaction, captured through SSQ-12 and THI surveys, was assessed preoperatively and postoperatively. Statistical analyses evaluated the correlation and agreement between simulated and actual results.

Results: Preliminary observations suggest that softband simulations show potential for predicting postoperative hearing thresholds, though variability in individual outcomes underscores the need for further analysis. Data collection is ongoing; analyses will evaluate concordance between preoperative and postoperative measures, including speech perception scores and patient-reported satisfaction through SSQ-12 and THI surveys.

Conclusions: Softband simulations provide a method for predicting postoperative outcomes in BCD candidates, supporting preoperative counseling and patient decision-making. The findings of this study will characterize the accuracy of softband simulations in guiding patient decision-making.
