Whether a tear in the external auricle can be cured depends on the size of the tear, whether it is secondary to infection, and the resistance of the organism, and other factors, and cannot be generalized. It is recommended that patients should consult a doctor in a timely manner and be evaluated by the doctor with specific clinical manifestations.1. Self-healing is possible: After an external auricular tear, if the torn wound is small and does not require suturing, there is no obvious local infection, no flow of pus, running water, or obvious redness, and the patient’s organism resistance is strong at the same time. At this time, as long as the trauma is kept dry and not touched by hands frequently, it will generally heal itself after 7-10 days. 2. The wound needs to be sutured to avoid external pathogenic microorganisms from entering the organism through the wound and causing the infection to worsen. In addition, the patient has to clean and disinfect the wounds regularly under the guidance of the doctor, such as disinfection with alcohol or iodophor. If necessary, ointments containing antibiotic ingredients, such as erythromycin ointment and pimaricin ointment, should also be applied. If the patient has local redness, swelling, pus and serious flowing water in the wound, oral or intravenous infusion of antibiotics, such as penicillin injection, ceftriaxone sodium injection, etc. is required.
