Surgical defects of the nasal ala are difficult to repair because of the need to preserve local function and the aesthetic aspect. Skin grafts are thin, pale, and have a smooth surface, which contrast with the skin of the nose. Flaps from the malar and proximal regions usually extend over the alar crease, causing deformities and obstruction of the nasal vestibule. The authors describe a reconstruction technique for defects of the nasal ala, which preserves the cosmetic unit without causing changes in the nasal vestibule or air flow.

Mohs Micrographic Surgery is regarded as a very useful technique for the excision of difficult to han- dle skin cancers. The procedure is divided into clearly defined steps: tumor evaluation and marking, tumor exeresis, tissue preparation and mapping, histologic processing and analysis, and closing of the surgical wound. The histologic analysis of all surgical margins leads to higher cure rates and tissue conservation, which make the procedure safer and more reliable.

The ear is a complex anatomical structure in which each subunit has unique characteristics. No single reconstruction technique could work in all situations; therefore, knowing different ways to reconstruct surgical defects in each one of these subunits is essential to achieving the best cosmetic results. We report here a detailed explanation of a superior helical advancement flap designated to repairs of the upper helical rim.
