[Epidemiology of auricular trauma]. / Zur Epidemiologie von Ohrmuschelverletzungen.

BACKGROUND: Auricular trauma is rare but can seriously reduce self-acceptance and function. Epidemiologic data on the causes of trauma causes and patient characteristics are limited. PATIENTS AND METHODS: The case notes of 141 from 197 patients with ear injuries have been reviewed retrospectively according to trauma cause and to the distribution of age and gender. RESULTS: Two thirds of the documented cases occurred between the age of 11 and 40 years. Men outnumbered women at a ratio of 2 to 1. The most frequent causes for ear trauma were traffic accidents (43 %), accidents at home (33 %), and fights (14 %). CONCLUSIONS: Mainly younger and active groups of the population are affected by ear trauma. Therefore, it is of particular concern in the acute setting to select those therapeutic options that have turned out good aesthetic and functional results in the long-term perspective.

[Auricular reconstruction for severe microtia. Schedule of treatment, operative strategy, and modifications]. / Ohrmuschelrekonstruktion bei hochgradiger Mikrotie. Behandlungsplan, plastische Operation und deren Sonderformen.

The incidence of microtia in Germany is 100-150 per year. These cases require a specific and challenging therapy. All patients need audiologic consultation. If desired plastic reconstruction is performed, which is aiming at achieving a lifelike as possible appearance corresponding to the shape of the opposite ear including an excellent skin color. The present paper describes background information, the interdisciplinary schedule of treatment, and the results of our operative strategy in two to three steps using autologous rib cartilage. Furthermore we expand on anomalous cases of microtia which require a modified procedure. In dystopic microtia, repositioning of the rudiment is necessary before reconstruction. In cases of excessive scar tissue due to injuries or previous operations, a one-step reconstruction using an axial fascia flap can be useful.

[Cutaneous form of sarcoidosis at the auricle]. / Kutane Manifestation einer Sarkoidose an der Ohrmuschel.

Sarkoidosis is a disease of so far unknown etiology that can affect potentially every organ. Sarcoidosis of the lung is the most common form, nevertheless in more than one third of the cases the head and neck area is affected. Manifestations of the disease can be present in lymph nodes of the neck, the middle ear, the pars petrosa of the temporal bone and in the paranasal sinuses as well as in the larynx and pharynx. We would like to present two rare manifestations of sarkoidosis of the ear lobe. The cutaneous form of sarcoidosis is characterized by a spectrum of skin changes. Aside from the physical presentation and observation of the disease progress the diagnosis is confirmed histologically. A multidisciplinary care of the affected patients is needed to diagnose the systemic extend of the disease on one side and to provide the patient with an effective therapeutic regimen that includes surgical and conservative measures on the other.
