title: Tissue remodeling in chronic rhinosinusitis.
abstract: OBJECTIVE
  To summarize the current knowledge on remodeling in chronic sinus disease.
  
  
  RESULTS
  Chronic sinus disease is characterized by persistent inflammation of the nasal and paranasal mucosa and is currently classified into two major subgroups on the basis of the absence (CRSsNP) or presence (CRSwNP) of nasal polyps. Transforming growth factor-beta and matrix metalloproteinases are critical factors involved in the remodeling process.
  
  
  CONCLUSIONS
  Remodeling is clearly present in chronic sinus disease. Transforming growth factor-beta has been implicated as an important factor in remodeling processes involved in chronic sinus disease, and serves as a main switch for different remodeling patterns in chronic sinus disease.
