Question
What precautions should be taken for congenital preauricular sinus?
Answer
Congenital preauricular sinus is a commonly diagnosed congenital external ear disease in clinical practice. It is a remnant of the incomplete fusion of the auricle primordia during the growth and development process of the second and second arches. The hereditary characteristics are typically dominant and can be inherited across generations. The sinus opening is usually located in front of the helix, with a few cases possibly occurring in the triangular fossa of the auricle or in the concha. Congenital preauricular sinus can be classified into simple, infected, and secretory types. Generally, there are no symptoms. Light pressure may cause a thin mucous or milky-like secretion to flow out of the sinus opening, accompanied by local itching and discomfort. For those without symptoms or infection, no treatment is necessary. For those with local itching and secretion, surgical removal is recommended.
