The paronychia, also known as the ear lump, commonly known as the small ear, is due to the abnormal development of the first gill arch, usually in front of the ear screen and the angle of the line of the mouth appear in different sizes and shapes of redundant tissues, there are often a number of cartilaginous tissues within the tissues, and the skin surface will sometimes be coloring, the paronychia is a completely redundant tissue, and has nothing to do with the function of the hearing and other functions, although the paronychial cartilage can sometimes be attached to the ear cartilage, and sometimes into the cheeks of the Although the cartilage is sometimes connected to the cartilage of the ear, and sometimes extends into the tissues of the cheek, it is a waste of tissue that serves no purpose. The paronychia needs to be differentiated from the following symptoms: Protruding auricle: Patients with Bart’s syndrome have a peculiar appearance, with a large head, prominent forehead, triangular-shaped face, protruding auricle, large eyes, and a drooping mouth. The clinical manifestations of the disease are complex and varied, with hypokalemic symptoms predominating. Bartter’s syndrome in the fetal period manifests as intermittent episodes of polydipsia, leading to the development of amniotic fluid overload at 22 to 24 weeks of gestation, which requires repeated amniotic fluid withdrawals to prevent preterm labor. Recessed Ear Circumference: Facial features of pediatric DiGeorge syndrome include an elongated face, bulbous nasal tip and narrow nasal wings, cleft palate, flattened zygomatic bones, widened eye spacing, squinted eyes, low-slung ears with recessed ear circumference, and a small jaw. Facial features include an elongated face, bulbous nasal tip and narrow nasal wings, cleft palate, flattened zygomatic bones, widened eye spacing, squinted eyes, low-slung ears with depressed ear circumference and a hypoplastic earwheel, and a small jaw. Other rare physical anomalies are microcephaly, short stature, elongated fingers and toes, inguinal hernia and scoliosis. Tough solid mass in the subauricular region: A mixed parotid tumor or pleomorphic adenoma is a tumor of the parotid gland that contains parotid tissue, mucus, and cartilaginous tissue, hence the name “mixed tumor”. The mucus and cartilage-like tissue are metamorphosed from glandular tissue. The outer layer of the tumor is a very thin envelope, which is formed by the deformation of the parotid tissue after pressure, and is not a true envelope.
