title: Horizontal stretching concept in oncologic dermatologic surgery of the face.
abstract: BACKGROUND
  Skin cancer surgery is usually performed on the face, and more specifically on and around the midfacial apertures. Each defect generated by the exeresis of a face tumor can be repaired by various advancement, rotation or transposition flaps techniques. Therefore the choice of the closure axis of a defect and its cicatricial and orificial consequences is decisive.
  
  
  RESULTS
  The closure of a defect is usually made by symmetrically suturing its edges, across the incision axis according to the rule of halves. However, the closure axis of a defect is intentional and characterized by the subcutaneous suture axis which determines the induced tension orientation, and thus the possible displacement of the aperture free margins. The horizontal stretching principle guarantees the lack of impact on the 3 major apertures of the midfacial frame: eye, nostril and mouth.
  
  
  CONCLUSIONS
  This biomechanical concept is decisive to repair midfacial defect with functional and aesthetic results. It also provides objective arguments for the reparative techniques prioritization and the ability to codify those to be recommended as first-line treatment in the surgical management of the face cutaneous tumours.
