title: Question mark ears and post-auricular tags.
abstract: Questions mark ears are an easily recognisable but uncommon malformation of the external ear. They can be found as an isolated malformation and are a pathognomonic sign of the auriculo-condylar syndrome. An additional unique sign in this syndrome may be present in the form of post-auricular tags. Such malformations should prompt further investigation for other signs of the auriculo-condylar syndrome.
