Purpose: Present surgical techniques for converting percutaneous (PC) to transcutaneous (TC) BCD devices and for electrode placement in revision CI cases.

Methods: We reviewed 16 patients converting PC to a TC BCD and 18 revision CI cases in our single implant center October1, 2023-July 30, 2026.

Results: Reasons for converting to TC BCD included extruded the abutment/fixture from persistent granulation tissue with superficial infection, skin breakdown, chronic recurring granulation tissue around the abutment and elective change to a TC device. The CI group included revisions for device malfunction, delayed infection, basal turn ossification, and unexpected cochlear duct soft tissue obstruction. Scalp flap revision and management of internal device components are reviewed in video and pictorial formats. In the CI cases, the use of SMART-Nav intraoperatively was used to verify electrode placement after revision. Wound complications, facial nerve stimulation, balance issues, and comparison to prior performance will be presented. Pedicled scalp rotation flap design, antibiotic utilization and implanted fixture assessment will be discussed.

Conclusion: Common principles for managing the soft tissue of the scalp when revising BCD and CI will be presented in an interactive format. Managing implanted fixtures and CI electrodes will be addressed separately with emphasis on optimizing postop healing and auditory performance.

Introduction: Chronic tinnitus causes significant subjective distress. While cognitive-behavioral group interventions facilitate habituation, limited research has explored how personality traits and home practice compliance predict treatment outcomes. This study evaluated the effectiveness of a group-based skill-development intervention for tinnitus coping, and investigated the predictive power of the Big Five personality dimensions and home practice intensity on post-intervention outcomes.

Methods: Using a pre-post design (N = 93), tinnitus distress was measured using the Tinnitus Handicap Inventory (THI), and personality was assessed via the BFI-10. At post-intervention, sessions attended and self-reported home practice frequency were recorded, while controlling for psychiatric history. Data were analyzed using a Wilcoxon signed-ranks test and a two-stage hierarchical linear regression. Additionally, the correlation between Openness and somatosensory amplification (SAS) was examined.

Results: At the group level, a highly significant reduction in tinnitus distress was observed (Z = -7.33, p < .001), with 81.7% of the participants showing improvement. In the hierarchical regression, the first block of control variables (baseline THI, age, sessions, psychiatric history, practice) accounted for 49.8% of the variance in post-test THI scores (Adj. R2 = .436). The inclusion of Big Five dimensions in the second block significantly increased the explained variance to 58.5% (Adj. R2 = .466, Delta R2 = .087). In the final model, home practice intensity was a significant positive predictor (B = 0.380, p = .033), and Openness demonstrated a strong trend-level effect (B = 3.348, p = .063). Openness also correlated significantly with somatosensory amplification (r = .198, p = .044).

Conclusions: The intervention effectively reduces tinnitus distress. The positive predictive value of home practice and Openness reflects need-based compliance and a reflective cognitive style. Patients with higher baseline distress and somatic amplification may invest more effort into practicing, maintaining a heightened sensory focus that results in higher absolute post-test scores despite overall clinical improvement.
