Frostbite

📋Overview

This condition occurs when tissues are subjected to extreme cold, leading to the formation of ice crystals within the cells and a reduction in blood flow to the affected areas. It most frequently involves the body's extremities, including the fingers, toes, nose, ears, and cheeks, where blood circulation may be more easily compromised by cold environments.

Clinical observations categorize these injuries based on the depth of tissue involvement, with milder forms historically referred to as frostnip. The physiological response involves both direct thermal damage to the cellular structure and indirect damage caused by vascular changes during the freezing process.
