Figure 32: a – incision for the skin-platysma-fascia graft, hatched areas = parts of the flap are de-epithelized in order to place them under the skin, via the paramedian incision, the trachea and cricoid cartilage are exposed; b – the graft is circumcised, the platysma with its fascia on the inferior surface is prepared from the cervical muscles; c – after suturing the cranially pedicled mucosal flap from the posterior tracheal wall as covering on the side of the trachea, the graft is also used for defect covering of the donor site of the mucosal flap; d – donor site of the cranially pedicled mucosal flap of the posterior tracheal wall (star) is visible, partial resection of a part of the 1st and/or 2nd tracheal ring in order to avoid pressure on the pedicle.
