Tympanic membrane injury can be categorized into two types, one is perforation of the tympanic membrane due to acute trauma, which can be seen on examination as bloody secretion from the external auditory canal, and a circular perforation in the loose part of the tympanic membrane, with the surface covered with blood. It will cause the patient’s hearing loss, tinnitus, ear pain and other related symptoms. For treatment, oral anti-inflammatory medication is needed to avoid local infection, no forceful nose blowing and avoiding colds, which can be cured in about one month. If it cannot be cured, surgical treatment is needed and tympanic membrane repair can be performed. Another possibility is perforation due to purulent otitis media caused by acute inflammatory infection. This type of perforation is usually seen on examination of the tense portion of the tympanic membrane as a large circular perforation in the tense portion of the tympanic membrane, with purulent secretions oozing out. In terms of treatment, purulent otitis media also requires symptomatic anti-inflammatory treatment, which can be inputted with medications such as ceftriaxone sodium, cefotaxime sodium, amitraz, meropenem, etc., and can be gradually cured in a week, and when the cure is followed by a thorough drying of the ear for six months later, surgical treatment is required.
