Abstract

Skin cancers of the head and neck treated by Mohs micrographic surgery often leave wound defects requiring advance reconstruction. Interpolation flaps, including the pedicled melolabial, paranasal, and retroauricular, are sophisticated and reliable options for large defects in facial areas. The paramedian forehead flap is a classic example of an interpolation flap, and it will be discussed in another chapter. The melolabial flap, also known as the cheek-to-nose interpolation flap, is a two-stage flap classically utilized for defects involving the nasal ala, inferior nasal tip, or columella. One limitation to the use of this flap is the resulting asymmetry of the melolabial folds. The paranasal flap overcomes this pitfall and is an excellent option for small to medium alar defects. Both flaps are generously vascularized by tributaries of the angular artery. The retroauricular flap is useful for full-thickness defects of the ear. Classically, this flap is used for defects on the middle third of the ear. However, it can also be utilized for defects on the inferior aspect of the ear, closer to the earlobe. These interpolation flaps, when utilized skillfully, can provide excellent cosmetic results and offer viable options for repair of defects of the nose and ear.
