title: [Large facial defect reconstruction with partition pre-expanded cervico-scapulo-dorsal flaps based on the superficial cervical artery].
abstract: OBJECTIVE
  To assess the outcome of large facial defect reconstruction with "partition" pre-expanded cervico-scapulo-dorsal flaps (CSDF) based on the superficial cervical artery (SCA).
  
  
  METHODS
  Surgical course consisted of 3 stages. In stage I, a skin flap was designed along the axis of SCA according to the facial defect and an expander was implanted in the cervico-scapulo-dorsal region by means of "partition" expansion. The expanders were implanted beside the flap axis and beneath the posterior half of flaps so as to expand only half area of the flap. During the stage II, expanders were injected with saline regularly for continuous expansion. In stage III, the pre-expanded CSDFs were transferred to cover the facial defect of which the CSDFs included about half of non-expanded area.
  
  
  RESULTS
  From November of 2008 to December of 2013, 15 patients with facial hypertrophic scar or scar contracture were reconstructed with pre-expanded CSDF based on the SCA. The expansion lasted for 3 to 4 months, and the expanded volume varied from 680 to 960 ml. One case of 4.0 cm x 1.5 cm epidermal flap necrosis occurred and healed subsequently with superficial scar; and another case of blister formation in the distal part of flap was found, which recovered without scar; the other 13 flaps survived without complications. After a follow-up for 12 to 38 months( average 26. 2 months), patients regained satisfactory appearance of face, with no obvious hypertrophic scar in the donor site.
  
  
  CONCLUSIONS
  Partition preexpanded CSDF based on the SCA is a good choice for large facial defect reconstruction, and the partition expansion is an effective strategy for prevention of venous congestion.
