A hole in the ear is clinically referred to as a congenital preauricular fistula, which occurs in the area of the angle of the ear chakra, or in some patients in the triangular fossa or inside the earnail cavity. Preauricular fistula clinically grows mainly due to congenital genetic causes, mainly due to incomplete fusion of the first and second gill arches during development, and it is a dominantly inherited disease that many patients have in their families such as parents, and children may have it. This disease can be seen as soon as the child is born. In addition to genetic factors, the appearance of this condition may also be related to the parents having viral infections, drug stimulation, genetic mutations and other factors during pregnancy. Clinically, for this disease, it is recommended to keep the local area of the ear dry and hygienic, and if there is no local redness or swelling and no obvious infection, it can be left untreated. Once the local infection is easily recurring afterwards, and finally, if you want to treat it completely, you need to undergo surgery to eradicate it.
