When pulling out the ear accidentally touches the inside of the ear, it is recommended that the patient should go to an ENT clinic to have an electronic tympanic membrane examination done by a doctor to determine the damage to the ear canal wall as well as the tympanic membrane. Generally speaking, there are the following scenarios: First, if the damage is only to the ear canal wall, the patient may have earache or bleeding in the ear canal, without damage to the eardrum. Generally this is not a big problem, the doctor can use suction to remove the blood in the ear canal, and can use local antibiotic ear drops to prevent and control infection. If the wound is large, oral antibiotics can also be used to prevent and control infection. Usually, most patients have a significant recovery in a week or so. During this period to keep the ear canal dry, do not enter the water, so as not to induce infection aggravation. Secondly, the patient may have touched the ear canal more deeply, and there is damage to the tympanic membrane, in which case the patient will experience hearing loss, obvious ear pain, a small amount of bleeding and other related manifestations. Generally, in this case, the doctor should carry out local disinfection of the ear canal to avoid infection induced tympanic membrane wound infection, leading to further expansion of the perforation. Clinical anti-inflammatory, preventive and control of infection, most patients, as long as the perforation is not infected, should be able to grow back within 2 months. If the perforation is not healed within 2 months, tympanic membrane repair surgery can theoretically be considered.
