title: [Biomaterials used for reparative and reconstructive surgery].
abstract: OBJECTIVE
  To investigate the currently-used biomaterials in reparative and reconstructive surgery and to clarify the relationship between the development of biomaterials and the progress of reparative and reconstructive surgery.
  
  
  METHODS
  Based on the author's many years' scientific researches and combined with the literature available at home and abroad, the biomaterials used in the clinical practice, and their kinds and application fields were summarized.
  
  
  RESULTS
  Based on the sufficient knowledge of the component structure of biomaterials and the patient's pathological status, the matching biomaterials could be designed and developed. According to the analysis on some common defects occurring in the skin, bone, cartilage, vocal cord, nerve, and drum membrane, the methods of repairing the defects with biomaterials that we had developed, such as collagen, chitosan, and hyaluronate, achieved good results.
  
  
  CONCLUSIONS
  The rapid development of biomaterials can greatly promote progress of reparative and reconstructive surgery and there exists a dependence relationship between the two. The related histological responses and the importance of biological estimation after implantation of biomaterials should be emphasized.
