definitionCongenital branchial fistulas are attributed to maldevelopment of the branchial system. A skin tag, sometimes containing cartilage, may mark the site of the opening. There is frequently a discharge, and infection may occur. Branchial fistulas may also appear in association with the Melnick-Fraser syndrome, in which pre-auricular pits, hearing loss and renal anomalies are also present. | synonymsBranchial Fistulas |
