(1) Formation of cicatrix of trachea was observed by endoscopy on day 4, 9, 14 and 19, and the degree of stenosis was calculated.

(2) Objective:To evaluate the three methods of reconstructing cicatrix contracture on the face and anterior neck.

(3) As one of the most common disease , cicatrix is the hotspot and focus of plastic surgery field at all times.

(4) Objective To observe osteogenesis of percutaneous autogenous bone marrow into cicatrix of bone defect.

(5) The results showed 8 cases were diagnosed as local recurrences of tumour and 4 cases as tumour caused by cicatrix accretion.

(6) The four main pathological factors that cause disorder of dynamic balance are: adhesion, cicatrix, contracture, and block.

(7) Objective: X ray features of osteogenesis of percutaneous bone marrow into cicatrix of bone defect were observed.
