A New Wide-Diameter Bone-Anchored Hearing Implant—Prospective 1-Year Data on Complications, Implant Stability, and Survival

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.
