title: Framework changes using costal cartilage for microtia reconstruction.
abstract: OBJECTIVE
  Since a known growth-of-cartilage framework is used for reconstruction of microtia under the Brent technique, we set out to address the behavior of the framework under the Nagata technique.
  
  
  METHODS
  A retrospective analysis of costal cartilage auricular reconstruction procedures.
  
  
  METHODS
  A total of 28 patients who underwent costal cartilage auricular reconstruction between 1998 and 2005.
  
  
  METHODS
  Reconstruction of microtia using the 2-stage Nagata technique.
  
  
  METHODS
  The parameters checked were patient age at the time of reconstruction, follow-up time, and measurements of the auricular framework height and width both at the time of implantation (represented by the template size) and at final follow-up.
  
  
  RESULTS
  A significant change in auricular height and width was observed. The height decreased by 3.1%, while the width increased by 4.0%. This change was not influenced by follow-up time.
  
  
  CONCLUSIONS
  Auricular reconstruction with the Nagata technique was undertaken when the patients were aged 9 to 10 years, when the auricle had reached nearly its final size. According to our patient sample, it is our opinion that a policy change is unjustifiable.
