title: A new wide-diameter bone-anchored hearing implant-prospective 1-year data on complications, implant stability, and survival.
abstract: OBJECTIVE
  To investigate a new wide bone-anchored hearing implant considering initial stability, stability over time, implant loss, and skin reaction.
  
  
  METHODS
  Consecutive, prospective case series.
  
  
  METHODS
  Tertiary referral center.
  
  
  METHODS
  Twenty adult patients were enrolled. All operations were 1-stage, single-incision technique with subcutaneous reduction.
  
  
  METHODS
  Measurement of implant stability.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  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.
