Children often play curiously and tend to stuff small objects they play with in their hands into their nasal cavity. Since they are too young to express themselves or older children are afraid of parental reprimand, they are afraid to tell their parents at that time and forget about it over time. When the typical symptoms of nasal foreign body such as nasal congestion, pus and unilateral nasal malodor appear, treatment is often delayed and causes complications such as sinusitis and bronchitis. Among the many varieties of nasal abiotic foreign bodies such as small playthings, plastic beads, glass balls, rubber heads, metal bullets, small stones, small ornaments, grains and cereals, button batteries are the most dangerous. Once in the nasal cavity, a short time will soon corrode the nasal mucosa, causing mucosal necrosis and erosion or even nasal septum perforation.
1, button battery contains chromium, mercury, cadmium, lead, manganese, nickel and other heavy metals, into the nasal cavity after the chemical reaction, the battery case broken, toxic substances leakage, serious corrosion of the nasal mucosa, including chromate and mercuric oxide corrosive strongest.
2.The leaking electrolyte solution gradually causes liquefaction and necrosis of mucous membrane.
3.The battery short-circuits and discharges heat in the well-conducted moist nasal cavity, causing serious burns to the mucosa and cartilage of the nasal septum.
4.The mechanical compression of the local mucosa by the foreign body causes mucosal necrosis.
5.The chemical substances zinc oxide and silver on the surface of the battery can chemically react with the proteins of the nasal mucosa.
In addition: heavy metals absorbed by the body can remain in the body for a long time leading to chronic poisoning, causing central, digestive, respiratory and other system diseases.
