Characterization of biophysical properties of rabbit auricle reshaped via diode laser (λ =980 nm)

摘要

Laser cartilage reshaping is a temperature dependent process that results in stress relaxation with subsequent formation of a new and stable specimen's geometry. This temperature dependent process results in mechanical stress relaxation and is characteristic of a phase transformation. The objective of this study was to quantitavely measure changes in tensile elongation and elastic modulus of rabbit auricle cartilage reshaped via diode laser (980 nm) and irradiated in two different protocols. The results revealed that the laser irradiation parameter used in cartilage reshaping does not produce significant irreversible changes in mechanical properties of the cartilage tissue. So diode laser can be considered as one of efficient tools in cartilage reshaping.
