title: The importance of maintaining the alar-facial sulcus in nasal reconstruction.
abstract: The alar-facial sulcus is an important topographical region because it represents a junctional zone of three cosmetic units: the nasal base, the medial aspect of the cheek, and the upper lip. Too often, the sulcus is violated by transposition flaps that have been harvested from the cheek to reconstruct defects of the nasal-alar lobule. When the sulcus is violated by surgery, it is difficult to restore a completely natural appearance. For this reason, we suggest an alternative method of reconstructing the alar lobule through the use of an interpolated flap. When defects extend into the alar-facial sulcus, reconstruction of the sulcus is necessary and should be accomplished with a separate skin flap from that used to repair the nasal component of the defect. When a single flap is used to reconstruct both lobule and sulcus, restoration of a completely natural-appearing sulcus is rarely achieved and usually involves multiple surgical procedures often facilitated by aggressive flap contouring, secondary intention healing, and Z-plasty. We describe our methodology in restoring the alar-facial sulcus after nasal reconstruction.
