What is an earphone?

Question 1: What is auricular fossa? Congenital preauricular fistula is a common congenital external ear disease in clinic. It is a relic of incomplete fusion of auricle primordia of the first and second branchial arches, and its genetic characteristics are autosomal dominant inheritance. Fistula is mostly located in front of the foot of helix, and a few can be located in the triangular fossa of auricle or concha cavity. Congenital preauricular fistula can be divided into simple type, infectious type and secretory type. Generally asymptomatic. When pressed, a little thin mucus or milky white sebum may overflow from the fistula, causing local itching and discomfort. Asymptomatic or non-infected people may not be treated. Local itching and secretion overflow should be surgically removed.

Question 2: From the perspective of physiognomy. What's in the eardrum? As the saying goes, "grain is stored in the front warehouse, chaff is stored in the back warehouse, and clothes are hidden on the ear." According to grandma, some babies have a small hole in the front or back of their ears after birth, and some are in the auricle, which is considered as a kind of "blessing".

My ears are symmetrical, and the old man said yes.

To be exact, I have two right ears. When I was very young, my right ear became inflamed. After treatment for a long time, it didn't heal. After suffering a lot, I met a noble fortune teller. At that time, listening to my grandmother's memories, I prepared all kinds of bones before I was cured (the medical conditions were not good when I was a child), so I was very careful not to get infected, that is, I should be fine without anything to buckle, and my hearing will not be affected in all aspects.

Question 3: Who is wearing headphones? Who the hell is it? Is a normal person. What a strange question you asked!

Question 4: Old people say that there is rice in the front ear storehouse and chaff in the back ear storehouse, so what is an ear storehouse? As the saying goes, "grain is stored in the front warehouse, chaff is stored in the back warehouse, and clothes are stored in the ear." Some babies have a small hole in front of their ears after birth, which is considered as "good luck".

Is that really the case? How is this small hole formed? What effect does it have on the human body?

Scientific principles/background knowledge:

The preauricular foramen, medically called preauricular sinus (or fistula), is a relic caused by incomplete fusion of the first branchial fissure groove during embryonic development.

Domestic statistics show that there are more girls than boys on one side than on both sides. It can grow in front of the ear, in the helix, behind the ear and even in the ear hole. There are blind ducts under the foramen, with different depths and sizes, and some have branches, which are connected with cartilage and even penetrate cartilage, and are several millimeters to several centimeters long.

There may be a small amount of white mucus or sebum-like substance at the extrusion nozzle, which has a bad smell and is often accompanied by itching. When the preauricular sinus is infected, the surrounding skin is red, swollen and even purulent, so it is necessary to cut and drain the pus.

The infected sinus should be operated in time after the infection is cured.

Most ear sinuses may not be inflamed for a lifetime and do not need treatment. Don't squeeze the sinus ostium by hand at ordinary times, and keep it clean locally.

The preauricular sinus has nothing to do with hearing.

Question 5: What does Ear Cangzi mean in Northeast dialect? Preauricular fistula

Question 6: What does the ear compartment length mean? Ear chamber is a congenital preauricular fistula and a common ear disease. It is caused by poor fusion of the first and second branchial arch mound nodules that form auricle in embryonic stage or incomplete sealing of the first branchial groove. It is a congenital developmental malformation, which is divided into three types: simple type, infectious type and secretory type. If the preauricular fistula is often inflamed, it needs to be surgically removed.
