auxiliary ear
Introduction
Introduction to the secondary ear The accessory ear is also called deafness, commonly known as the small ear. It is caused by the abnormal development of the first zygomatic arch. Usually, there are different types of twin tissues in the front and the corner of the tragus. There are often several cartilage tissues in the tissue. The surface of the skin is sometimes colored, and the accessory ear is completely redundant. It has nothing to do with hearing and other functions, although sometimes the accessory ear cartilage can be connected to the ear cartilage and sometimes into the tissue of the cheek, but both It is an abolished organization that has no effect. basic knowledge The proportion of sickness: 1.2% Susceptible people: no specific population Mode of infection: non-infectious Complications: pharyngeal insufficiency
Cause
Secondary ear cause
Cause:
The accessory ear originates from the auricular nodules or the soft tissue surrounding the 2nd, 3rd, and 4th cleft palate due to abnormal development. Many patients are sporadic, but some families may be irregularly dominant. Mainly during the pregnancy to use drugs. There are also some fetal malformations caused by radiation. In general, many amino sugar drugs can cause teratogenicity during pregnancy, and it is best to pay attention to prevention.
Prevention
Secondary ear prevention
Be careful not to take medicine during the main pregnancy, pay attention to radiation protection, and do not do all the influential tests. Attention is prevention during the fetal period. Try to eat less spicy and irritating food. For example: onions, peppers, peppers, peppers, mustard, fennel. Avoid eating fried, greasy food. Such as fritters, butter, butter, chocolate, etc.
Complication
Secondary ear complications Complications, velopharyngeal insufficiency
Some patients (about 5%) have abnormal pharyngeal arch development. Patients with Goldenhar syndrome are often accompanied by a pair of ears.
Symptom
Secondary ear symptoms common symptoms nodules
The main lesions are small skin-colored fragments or soft globular nodules, or cartilage-like hardness, starting from the tragus or near-ear screen along the tragus to the line of the mouth, or along the anterior border of the sternocleidomastoid muscle . It can be bilateral, and it can be accompanied by bronchospasm in the neck.
Examine
Secondary ear inspection
Generally, the accessory ear can be considered for surgical resection, and the person who does not affect the appearance can not be treated. Generally, a tough mass in the subauricular area can be seen through visual inspection: a mixed tumor of the parotid gland or a pleomorphic adenoma is a parotid tumor containing parotid tissue, mucus and cartilage-like tissue, so it is called a "mixed tumor." Mucus and cartilage-like tissue are metamorphosed by glandular tissue. The outer layer of the tumor is a very thin envelope that is formed by deformation of the parotid gland after compression and is not a true envelope. Can be diagnosed.
Diagnosis
Diagnostic identification of the auricle
Differential diagnosis of the accessory ear:
1. Skin sputum: Skin sputum refers to a soft, skin-colored growth organism that attaches to the surface of the skin through a fine pedicle-like tissue. Its medical name is called soft cocoon. The skin is not a skin cancer or a skin. Cancer. The typical skin sputum is a characteristic of age. It is especially common among the elderly over the age of 60. It is more common in women and tends to be familial. It is also common after pregnancy. The skin is most likely to grow on the skin. Wrinkled areas, neck, armpits, torso, under the breast or genital area. If clothing or jewelry rubs them, it may cause irritation and affect the appearance.
2, the submental area of the tough mass: parotid mixed tumor or pleomorphic adenoma is a kind of parotid gland tumor containing parotid tissue, mucus and cartilage-like tissue, it is called "mixed tumor". Mucus and cartilage-like tissue are metamorphosed by glandular tissue. The outer layer of the tumor is a very thin envelope that is formed by deformation of the parotid gland after compression and is not a true envelope.
