Abstract:
OBJECTIVETo explore biomechanical properties and stress-strain of mucosa scars after cleft palate surgery.
METHODSAfter the model of mucosa scars was made, the mucosa scars and normal mucosa were excised and examined immediately by tensionometry.
RESULTSThe mucosa scars after cleft palate surgery were compared with normal mucosa. The Poisson's ratio of mucosa scars and normal mucosa was 0.5 and 0.49, respectively, showing no significant difference between the two groups. The ultimate Young's modulus of mucosa scars was about 24.22 MPa, however, it declined to 3.32 Mpa in normal mucosa.
CONCLUSIONSThe mucosa scars after cleft palate surgery are biomechanically weaker than normal mucosa. It can be used for further research, such as maxillary orthognathic surgery, distraction osteogenesis, and orthodontic treatment.
