Summary

The term microtia describes the relatively rare spectrum of congenital malformations of the external ear, varying from minimal structural abnormalities to a complete absence of the external ear. De exact etiology of microtia is unknown, but it is believed to be multifactorial with both genetic- and environmental components. Most patients with microtia have accompanying anomalies, such as aural atresia, soft tissue asymmetry, hypoplasia of the jaw and facial nerve paralysis. In some cases, microtia occurs as part of a syndrome.

Due to the rarity of the condition and the extensive variety in phenotypic expression, not many healthcare workers are familiar with microtia and its associated functional, aesthetic and psychological impact. There is no clear, generalizable and standard care pathway for these patients, due to the broad variety of associated congenital anomalies. The aim of this thesis, therefore, is to highlight several important factors that help individualize the treatment plan for patients with microtia. We have broadly looked at the information process after birth, the development of children with microtia, and the surgical techniques for auricular reconstruction in subgroups of patients with “unconventional” microtia
