Accessory tragus in Adult
In most cases, there are no associated underlying developmental or syndromic findings; however, cleft lip or cleft palate may occasionally be seen. Syndromic associations include Goldenhar syndrome, Townes-Brocks syndrome, Treacher-Collins syndrome, VACTERL association (vertebral defects, anal atresia, cardiac defects, tracheoesophageal fistula, renal anomalies, and limb abnormalities), Wolf-Hirschhorn syndrome, and Wildervanck syndrome.
Some studies have suggested an association between accessory tragus and hearing deficits, but a previously reported association of underlying renal abnormalities has not been confirmed in larger, more recent studies.
