### Study: **Long-term, multi-center results with the BONEBRIDGE**

(Original title:

Long-Term, Multicenter Results With the First Transcutaneous Bone Conduction Implant, Otol Neurotol. 2021 Jul 1;42(6):858-866.; Sprinzl GM et al.)

### **Take home message**:

The BONEBRIDGE is a long-term safe and effective transcutaneous bone-conduction implant for children and adults.

### **Background:**

Short-term safety and effectiveness of the transcutaneous BONEBRIDGE implant has already been demonstrated. This study is looking at safety and results up to 36 months postoperatively, in children and adults.

### **Method:**

- 57 patients 
    - 49 adults (18-76 years)
    - 8 children (5-17 years)
- Multicenter, prospective study

###  Results:**

Device Safety:

- Minor adverse device effects (ADE): 24.6%
- 3% rated as serious ADE and resolved by revision surgery
- All ADE were resolved by the end of the study (change in magnet strength, painkillers,…)

Audiological outcomes:

- Preservation of hearing: patients’ AC and BC thresholds remained stable over study period
- Mean PT4 thresholds, soundfield thresholds and word recognition scores improved significantly at all time points following implantation.

Device satisfaction:

- Subjects were stably satisfied to very satisfied with the BONEBRIDGE device at 3 and 36 months postoperative, reflecting also in high wearing time.
