Objective:
To investigate a new wide bone-anchored hearing implant considering initial stability, stability over time, implant loss, and skin reaction.
Study Design:
Consecutive, prospective case series.
Setting:
Tertiary referral center.
Patients:
Twenty adult patients were enrolled. All operations were 1-stage, single-incision technique with subcutaneous reduction.
Intervention(S):
Measurement of implant stability.
Main Outcome Measure(S):
Implant stability quotient (ISQ) values were recorded using resonance frequency analysis at the time of implantation and at 10 days, 6 weeks, 6 months, and 1 year after surgery. Skin and soft tissue reactions according to Holgers grading system.
Results:
Implant stability quotient measurements revealed a significant increase in ISQ during the first 10 days after operation, and the ISQ values continued to rise throughout the 1-year observation period. No implants were lost. Skin and soft tissue reactions were rare and minor, as no reaction was seen in 93% of the follow-up examinations and no grade 4 reactions occurred.
Conclusion:
The new wide implant showed good stability at surgery. Osseointegration was fast, and implant stability increased throughout the 1-year observation period. No implants were lost. Skin and soft tissue reactions were rare and minor.
