Question
A five-year-old child had a fall on the face one month ago, and now the face has healed, but there is a lump where the injury occurred.
Answer
This condition may be due to tympanic membrane inflammation caused by trauma. It is recommended to undergo a surgical examination to determine the cause. If possible, an X-ray examination can be conducted to check for any bone damage. If there is bone damage, the possibility of complete recovery is relatively low, but cold compresses can be tried to promote healing.
