Preauricular fistula, or congenital preauricular fistula, is the remnant of the first parotid sulcus during the embryonic period. Most cases are unilateral. The fistula opening is often located in the forefoot of the helix. The fistula can form a branch or tree shape. The inner surface of the fistula is lined with stratified squamous epithelium. There are shed epithelium and keratin in the lumen. Due to infection and corruption, smelly tofu-like residue can be excreted. secretions. The disease is usually asymptomatic. Occasionally, a small amount of mucus or pus will overflow from the fistula when squeezed. When infected, the local area may be red, swollen, painful, or abscessed, or purulent secretions may increase. In case of repeated infections and suppuration, pus may form in the local area. Fistula or scar. Generally, asymptomatic people do not require treatment. If there is infection and suppuration, antibiotics or sulfa drugs can be given for treatment, such as penicillin, 800,000 units each time, intramuscular injection (pay attention to an allergy test); or erythromycin, 0.25g each time, 3 times a day, orally. If an abscess forms, it should be incised in time, pus should be drained, the area should be cleaned and disinfected, and the dressing should be changed with iodophor gauze. After the redness and swelling disappear and the infection is controlled, fistula resection can be performed. It must be completely removed at one time, otherwise the remaining part of the fistula will be infected again and the surgery will be performed again. The effect is very poor.

2. Relevant knowledge:

Auricular fistulas are caused by congenital formation, or incomplete treatment of post-auricular gangrene, or ulcers that remain unhealed for a long time. Fistula diseases are characterized by fistulas appearing in front of or behind the ears and sometimes exudation.

This disease is more common in congenital preauricular fistulas referred to in Western medicine and fistulas left after the rupture of subperiosteal abscesses behind the ears.

[Diagnostic basis]

1. In congenital cases, the fistula exists since birth and is often a blind tube, either deep or shallow, straight or curved. The opening is usually located in front of the tragus or helix, about the size of a sesame seed. There are usually no symptoms, but a small amount of milky white cheese-like substance is often discharged with a slight odor. If infected with evil poison, the fistula will be red, swollen, painful, and overflow with pus. After repeated attacks, the skin at the fistula becomes thinner and becomes a dark red thin scar.

2. Caused by auricular poisoning, the fistula is located in the skin below the mastoid process. The disease will not heal for more than three months, and the pus will continue to overflow. The amount is small and smelly, and the probe can touch the mastoid bone. .

[Syndrome differentiation and treatment]

1. Sepsis (accumulation) syndrome: The opening of the preauricular fistula is red, swollen and painful, with more or less pus overflowing. The tongue is red and fat, the coating is yellow and greasy, and the pulse is slippery and rapid. Drain pus and detoxify.

2. Syndrome of righteousness deficiency and evil love: the fistula at the tip of the mastoid process behind the ear does not close for a long time, and occasionally overflows thin pus with a slight odor, the sore is dark red, tired and weak, the tongue is pale, and the coating is thin. The pulse is thin, slow and weak. Strengthen the body, expel pus and detoxify.
