Thermal cauterization is a medical procedure that uses heat to destroy abnormal tissue or stop bleeding. This technique involves applying a heated instrument, such as a cautery pen, to the targeted area. The heat causes the tissue to coagulate, effectively sealing blood vessels and preventing further bleeding. This method is commonly used in surgeries and minor procedures, such as removing warts or treating nosebleeds. Thermal cauterization can help reduce the risk of infection and promote faster healing by minimizing open wounds. It is a quick and effective way to manage various medical conditions.
