Question
My son has congenital preauricular sinus. I want to know if this is related to genetics?
Answer
Congenital preauricular sinus may be hereditary. It is usually caused by the incomplete closure of the branchial cleft during embryonic development. The presence of similar symptoms in the patient’s family history, such as preauricular sinus, hemangioma, and finger curvature, may suggest a genetic predisposition. It is recommended to undergo detailed medical examination to determine the cause and take appropriate treatment measures.
