Patient's question:
I have a congenital preauricular fistula. I've been married for half a year and am now planning to have a child. I'm very worried about this condition being hereditary. Can congenital preauricular fistula be inherited?Doctor's answer:
Congenital preauricular fistula does not have a hereditary nature; it is simply a result of abnormal development. This condition is caused by the improper fusion of papillary nodules formed during the first and second branchial arches in the ear during embryonic development, or incomplete closure of the first branchial groove. It generally does not coexist with other ear deformities.
