When infected, the fistula is red, swollen, painful or abscess dissolved. After inflammation, the fistula will repeatedly become inflamed, fester and fester. The lumen will also develop deeply, and a few infections can extend to the external auditory canal or mastoid process, which is easily misdiagnosed as mastoiditis. People with repeated infections may have local long-term unhealed fistulas or scars, and the patients are very painful. Don't squeeze the secretion in the fistula at ordinary times to avoid infection.
[Treatment]: clearing away heat and toxic materials, reducing swelling and discharging pus.

It is often seen that there is a small hole in the skin in front of some people's ears, which is born from the uterus, sometimes one ear, sometimes two ears, which is more common in girls. These holes may not change for a lifetime, but sometimes a little bean curd residue will flow out of these holes, and it will often be red, swollen and painful, and yellow pus will flow out, even forming an abscess, which makes people feel at a loss. Why are these holes like this? How did they come from?
This kind of preauricular skin hole is called preauricular fistula in medicine. Because it is born, it is also called congenital preauricular fistula. It's congenital developmental abnormality and abnormal anatomical structure.
A few months before birth, a person looks a bit like a fish, because at this time, there are structures similar to fish gills on both sides of the embryonic head, called gill slits. As the human embryo grows up in the mother's stomach, these gill structures gradually close until they disappear, so that no trace can be seen after birth. But there are always some people whose branchial cleft will not be completely closed, so some skin pores will be left after birth. Congenital preauricular fistula is the relic of the first branchial fissure, with only one tube, which is a single outlet blind tube. Because these small pore tubes bend like branches, there may be branches extending into the meat, and the epithelium of the lumen has the characteristics similar to scalp desquamation, so some exfoliated epithelium and other keratin are often accumulated in the lumen. These exfoliated epithelium will block the nozzle, leading to poor drainage, which will easily cause inflammation and swelling once it meets water. If the lumen is still not well drained and pus cannot be discharged at this time, it will gather and swell under the skin to form cysts or abscesses.
If the congenital preauricular fistula is not inflamed, it will not feel anything, so you can leave it alone. Maybe it will never make waves, but it will never be used to breathe like a fish gill. Sometimes a small amount of mucus or bean curd residue can be squeezed out from the small hole with a gentle squeeze, which has no taste, but once infected, it will recur in the future, so it should be thoroughly removed in time. Because after the first infection of preauricular fistula, it often causes scar adhesion and drainage is more smooth. Sooner or later, the second and third infections will occur, eventually forming pus fistula and scar. Therefore, surgical treatment is a method of complete eradication and cannot be confused by the short-term recovery brought about by taking medicine and injections.
The operation of congenital preauricular fistula is actually very simple, but we should choose a good time. Patients with abscess and cyst should be treated with incision and drainage, oral or intravenous antibiotics and other drugs. Only when inflammation is almost under control can they be completely eliminated. As long as the surgical resection is complete, there will be no recurrence after operation.
