Is congenital preauricular sinus hereditary and can it be passed on to the next generation?

Congenital preauricular fistula may be inherited by the next generation, so timely examination is recommended.

Congenital preauricular fistula is a relatively common congenital ear deformity, usually caused by incomplete fusion during the development of the first and second branchial arches, resulting in a small tube in front of the ear. In most cases, it does not require treatment. This condition is genetically determined; if someone in the family has congenital preauricular fistula, it may indicate genetic inheritance. Although this situation is uncommon, once present, it is more prone to infection. In cases of suppurative infection, patients can take antibiotics under medical guidance, such as levofloxacin mesylate capsules, cefradine granules, or azithromycin tablets, to alleviate symptoms. However, for a small number of patients with severe infections that have developed into abscesses, incision and drainage under medical supervision may be necessary.

Patients with congenital preauricular fistula are advised to maintain good lifestyle habits, pay attention to personal hygiene, and engage in appropriate physical exercise to enhance their immune system.
