The older generation called it "Cang Yan" and thought that the child in this small hole was "rich" and would not worry about food and clothing in the future. Some people call it a "smart hole", thinking that this child will be very smart in the future.
Wishes are beautiful.
In fact, the real name of this small hole is "preauricular fistula", which is a congenital malformation! Many people still have it as adults.
Attention,
Don't touch this hole in your ear! Because of ignorance, a mother squeezed into the "rich man's hole" to make her newborn baby have plastic surgery!
Doudou has a small hole in his right ear since he was born. I didn't feel anything before, but recently I found that there was white secretion flowing out, and it would be a little smelly.
Mom Doudou thought it would be good to squeeze it out, but she was inflamed the next day. She ran to the hospital for examination, only to know that it was a preauricular fistula and needed immediate surgery.
Doudou's mother regretted it. If she had not been ignorant, the child would not have suffered such a crime at all.
How is the "rich hole" formed?
"Fu Kong" is called preauricular fistula in medicine. During embryonic development, the auricle primordia of the first and second branchial arches that develop into auricles are caused by incomplete closure during development, which is a congenital malformation.
Simply put, the place where the ear should be closed in the embryonic period was not closed well, leaving a small hole. This little hole leads to your unknown skull.
Preauricular fistula has obvious genetic tendency, and the incidence ratio of male to female is about 4: 1.
Once infected, it will recur!
Some people with preauricular fistula usually don't feel any discomfort. But once infected, it will recur in the future!
In acute inflammation, antibiotics should be used to control inflammation and local hot compress should be used. If an abscess has formed, you need to go to the hospital for surgery and drainage. After the infection is controlled, fistulectomy is performed to avoid repeated infection.
If the fistula is not removed, it is likely to cause scar adhesion, eventually forming pus fistula and scar, and even serious auricle deformity!
