All these reasons make it an ideal donor site for ear reconstruction. The authors propose their own algorithm for reconstruction of every kind of anterior defects of the auricle with different Retroauricular Island Flaps (RIFs) based on the location and size of the defect developed over a 16 years single institution's experience with a series of 216 consecutive cases. MATERIALS AND METHODS: 216 patients have undergone ear reconstruction with RIFs from 1999 to 2006. In 52 a Superior Pedicle RIF (SP-RIF) was used for defects of the upper half of the auricle. In 68 cases a Perforator RIF (P-RIF) was used for conchal reconstruction. In 96 cases an Inferior Pedicle RIF (IP-RIF) was used for reconstruction of nonmarginal and superficial marginal defects of the auricle. RESULTS: No flap failure was recorded. Excellent morphological reconstruction was obtained with these flaps with no sequealae at the donor site in terms of form and function. Only in the case of P-RIFs the sulcus becomes flat in its central part, but this has never affected the possibility of wearing spectacles. The SP-RIFs may sometimes show some signs of venous stasis that invariably resolve in the first two postoperative days. CONCLUSIONS: The retroauricular skin may be considered a flaps bank for ear reconstruction. It offers in fact a great variety of island flaps that are suitable for every kind of loss of substance of the ear, have a safe vascularisation, skin of similar colour and texture, are easy to harvest under local anaesthesia on an outpatient basis and cause no relevant morbidity at the donor site. Location and size of the defects lead the choice between the different types of RIFs.
