Patient's question:
Patient is male, 4 years old, refuses to eat, cries, unwilling to sleepDoctor's answer:
Okay, here is the English translation, following your instructions:It turns out that inside the middle ear cavity, there is a small tube leading to the nasopharynx, which is medically known as the Eustachian tube. Since a child's Eustachian tube is relatively short, wide, and straight, and is positioned horizontally, coupled with their weaker body resistance, they are prone to upper respiratory infections such as acute rhinitis and tonsillitis. Furthermore, certain infectious diseases like measles, scarlet fever, and influenza often cause increased secretions in the nasopharynx. Additionally, when an infant spits up milk, coughs violently, or blows their nose too forcefully, bacteria can easily enter the middle ear through the Eustachian tube and become the most common cause of purulent otitis media. Moreover, if a child's ear is cleaned improperly, accidentally damaging the outer ear canal lining or eardrum, this can lead to infection, which may then spread to the middle ear and cause inflammation.
