Due to the variety of abnormalities, surgery of the auricle is one of the most complex challenges in facial plastic surgery. They reach from mild protruding ears or isolated abnormalities of the supporting structures, mainly the helical rim and antihelix, over cup ear deformities and miniears all the way to severe microtia and anotia. In this article, the authors present a short overview of auricular abnormalities and malformations and their treatment options based on their experiences gained over three decades of special service for patients with auricular malformations., Competing Interests: None., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)

The construction of an auricle from autologous tissue is highly complex and demanding for a reconstructive surgeon. Depending on the characteristics of the underlying malformation, there are various surgical techniques available, which in specialized hands, promise regularly achievable attractive and stable results. To achieve this goal, a long-term training in super specialized centers is required. Training models available today, can partially systematize this training. The future of auricular reconstruction lies probably in the tissue engineering of organ complexes, including their nerve and vascular supply., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)

Although several techniques can be used for microtia repair, some standard procedures have been developed over the past few decades. In specialized centers, these techniques are performed most frequently. They include two to four operative steps using autogenous rib cartilage for the framework and local skin for its tegument. We have been using this technique presented here in more than 800 cases over the past two decades with good and mostly stable results., (Copyright Thieme Medical Publishers.)

Although the use of autogenous cartilage is the gold standard in auricular reconstruction, its main disadvantage is the morbidity due to harvesting the cartilage. This includes postoperative pain, visible scar, and possibly asymmetry and reduced stability of the thorax. To reduce all of these drawbacks, we describe some modifications that reduce pain to a low tolerable level, hide the scar invisibly in the submammary fold in females, and induce regeneration as well reestablish stability of the rib defect., (Copyright Thieme Medical Publishers.)

Auricular reconstruction is a challenging, mostly multistaged procedure that requires many different techniques. Whereas standard techniques have been developed for the standard severe, third-degree dysplasia, we are often confronted with severely scarred patients due to excess trauma or prior operations. These special situations need a variety of special techniques; some of those are described here to be considered as alternative options., (Copyright Thieme Medical Publishers.)
