title: Surgical treatment of retraction pocket with bone pate: scutum plasty for cholesteatoma.
abstract: OBJECTIVE
  Postoperative attic retraction pocket is a critical issue and may be indicative of disease recurrence after canal-up tympanoplasty for middle ear cholesteatoma. Although scutum plasty is an acceptable procedure that can be used to prevent the pocket formation, how the scutum is reconstructed has remained controversial. The aim of this study was to clarify the value of scutum plasty using bone pate.
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  Bone pate scutum plasty was performed in 69 ears during first-stage operations. We attempted to reconstruct a smooth attic bony wall. At the time of the second-stage operations, the results of the scutum plasty were examined.
  
  
  RESULTS
  The incidence of retraction pocket was statistically reduced from 20.2% to 5.8%.
  
  
  CONCLUSIONS
  Although the reconstructed scutum showed atrophy to some extent, bone pate scutum plasty is effective in preventing postoperative retraction pocket if a smoothly shaped attic wall can be reconstructed.
