title: TORP ossiculoplasty outcomes with and without a stapes footplate prosthesis.
abstract: OBJECTIVE
  The titanium stapes footplate prosthesis (FPP) was designed to ensure a stable connection of a total ossicular replacement prosthesis (TORP) to the stapes footplate and maximize acoustic coupling by centering the footplate on the oval window. Our goal was to assess the impact of the FPP on TORP ossiculoplasty outcomes.
  
  
  METHODS
  Case series with chart review.
  
  
  METHODS
  Tertiary care center.
  
  
  METHODS
  Adult patients undergoing TORP ossiculoplasty with (n=53) or without (n=108) a stapes FPP.
  
  
  METHODS
  Rate of prosthesis displacement and audiologic outcomes were tabulated for statistical analysis.
  
  
  RESULTS
  A lower rate of prosthesis displacement and statistically better audiologic outcomes were seen in FPP patients. The pure-tone average air-bone gap (PTA-ABG) was closed to <20 dB in 69.8% (37/53) of patients in the study arm and 44.4% (48/108) of patients in the control arm (P=.003). The PTA-ABG was decreased by a mean±SD of 19.3±11.7 dB and 12.6±11.0 dB in the study and control groups, respectively (P=.0012).
  
  
  CONCLUSIONS
  Use of the titanium stapes FPP during TORP ossiculoplasty provides a statistically significant advantage in short-term PTA-ABG closure and a higher rate of successful rehabilitation of conductive hearing loss. Further studies are necessary to assess any long-term advantages a FPP may offer.
