How does laser thermal energy vaporize tissue?

• A. Ionizing photonic interactions
• B. Reducing cellular size
• C. Selectively removing inorganic cellular components
• D. Rapidly boiling away inter- and intracellular fluid

Answer: (D)

Laser thermal energy vaporizes tissue primarily by rapidly boiling away inter- and intracellular fluid. When the laser is applied to the tissue, the thermal energy produced by the laser causes a quick rise in temperature. This increase in temperature leads to the conversion of the fluid within the cells and extracellular spaces to vapor. As the water content in the tissue heats up and reaches its boiling point, it transitions into vapor, effectively causing the tissue to disintegrate or be vaporized. This method of tissue removal is advantageous because it is highly selective, allowing for precise targeting of tissue while minimizing damage to surrounding structures. The rapid vaporization results in a sharp and clean removal of tissue, making it a preferred technique in various medical and cosmetic laser procedures. The effectiveness of this mechanism is key in many laser applications, as it allows for controlled and efficient tissue reduction during treatments.
