Cysts behind the ear include cystic type 1st gill groove fistula, sebaceous cyst, dermoid cyst, etc. Generally, cystic lesions are surgically resected in a complete manner, and repair and reconstruction of the structure and function of the operated area is carried out during the same period of surgery.
1. cystic type 1 gill groove fistula: this disease is caused by abnormal development of the first gill groove. The cystic type is manifested as a cystic mass with progressive enlargement below the back of the earlobe, without adhesion to the surface skin, often in the deep surface of the superficial lobe of the parotid gland, partially encapsulated within the parotid gland, and adjacent to the external trunk section of the temporal bone of the facial nerve. Surgery to completely remove the diseased tissue is the only way to cure the disease.
2. Sebaceous cysts: they are retention cysts caused by obstruction of excretion of sebaceous glands. When the cyst grows behind the ear, the surface of the cyst is often seen as a small black spot of the sebaceous gland opening. If there is no sign of infection, surgical excision should be performed on an elective basis.
3. Dermoid cyst: it is a kind of benign tumor with congenital developmental abnormality, which is related to the abnormal development of skin tissues in embryonic period. When it occurs behind the ear, it mainly manifests as a single painless subcutaneous nodule, which may increase slowly with age. Most often occurring in children, the most effective treatment is surgical removal of the cyst.
The most effective treatment is surgical removal of the cyst. When a cyst is found behind the ear, it is important to seek medical attention and treatment after evaluation by a specialist.
