1, congenital malformation: Some people are born with congenital malformation of ears and no helix. This may be caused by genetic factors, fetal development problems or other reasons. This condition may be isolated, involving only the loss of the helix, or it may occur together with other ear malformations.
2, trauma or surgery: trauma or surgery may lead to the loss of the helix. For example, after severe ear tearing or excision, the helix tissue may be damaged or completely removed. This condition usually needs to be repaired by plastic surgery.
3, skin lesions: some skin diseases may affect the formation of spiral. For example, some types of skin inflammation, ulcer or skin infection may lead to the damage or destruction of spiral tissue. The treatment of related skin injuries may require the intervention of doctors and appropriate treatment.
4. Infection or dysplasia: Some congenital infections or dysplasia may lead to the loss of the helix. For example, abnormal fetal development caused by congenital rubella syndrome may lead to ear deformities, including the absence of helix. Other similar infections or developmental abnormalities may also cause similar situations.
5. Other structural problems: In addition to the absence of the helix, there may be other problems related to the ear structure. Such as abnormal auricle size and shape or other ear tissue loss. These problems usually require customized medical intervention to restore normal appearance and function.
