First, if the patient accidentally bites the lip, accompanied by a mild local hematoma and caused by swelling. At this time, it is recommended that the patient apply local ice for 24 hours to reduce tissue exudation. 24 hours later, hot ointment pack can be applied externally and blood circulation and stasis cream can be applied externally to promote the absorption of swelling. Generally after 3-5 days, the hematoma of the lips can subside on its own. Second, the swelling caused by serious lacerations of the lips caused by the patient’s fall. Patients need to go to the hospital as soon as possible and perform disinfection treatment of the lip wound. Patients with active bleeding need to perform local stitches and stop bleeding. At this time, oral amoxicillin, cefixime and other anti-inflammatory drugs should be taken, and topical gold ointment should be applied to promote the reduction of local inflammation and edema. Some patients need about 14 days for the swelling of the lips to be slowly absorbed.
