| Outline of Final Research Achievements |
Twelve anterior chest wall models were established. Scars of three shapes were created in each model: i.e., round, transverse, and vertical scars. A load mimicking respiratory movement was applied.The maximal scar stresses were highest in the transverse scar groups and lowest in the round scar groups, with statistical significance in both male and female groups (all, P = 0.031). In the transverse scar models, maximal scar stresses were significantly higher in the male group than in the female group (P = 0.026).In both the round and transverse scar models, stresses were concentrated at the horizontal edges of scars.In the round and transverse scars, stress distribution patterns were consistent with the directions of keloid expansion. Our findings suggested that transverse scars are unfavorable in comparison with vertical scars in the anterior chest wall. The male models showed higher stresses than the female models.
