Clinical methods for the removal of petechiae are mainly as follows: First, patients can use local massage, physiotherapy, hot ointment pack external application, moxibustion strip fumigation, infrared irradiation methods to improve the blood circulation of local tissues, which can promote the self-absorption of petechiae. Second, for patients whose stasis points cannot be absorbed by local physical therapy, laser cauterization or liquid nitrogen freezing can be used to induce protein coagulation necrosis of local tissues, and the new granulation can dissolve and absorb the stasis points completely to achieve the purpose of removal. Third, if the patient’s petechiae are not eliminated in the process of active treatment, but there is a trend of progressive increase, the patient should pay sufficient attention to this time, if necessary, feasible surgical excision, so as to avoid local lesions, causing serious complications.
