    Abstract
  •   Objective  To explore the clinical effects of expanded flap made by skin and soft tissue expander (hereinafter referred to as expander) in repairing the wounds with exposed titanium mesh after cranioplasty with titanium mesh.  Methods  A retrospective observational study was conducted. From April 2015 to October 2019, 13 patients with wounds with exposed titanium mesh after cranioplasty with titanium mesh were admitted to the First Affiliated Hospital of Air Force Medical University, including 10 males and 3 females, aged 18 to 70 years. Exposure of titanium mesh occurred 3 months to 4 years after cranioplasty with titanium mesh. The wound area of exposed titanium mesh ranged from 1.5 cm×0.6 cm to 6.3 cm×6.0 cm. In the first stage, one or two square expanders with rated capacity of 50-200 mL were placed under the normal scalp 1 cm away from the edge of the wound surface of exposed titanium mesh. The water injection time was 2 to 3 months with the total water injection volume being 1.6 to 2.0 times of the rated capacity of expander. In the second stage, the expander was removed and the expanded flap (size ranging from 4.1 cm×1.8 cm to 9.1 cm×7.9 cm) was transferred to repair the wound of exposed titanium mesh. The placement site of the expander, the transfer form of the expanded flap, the postoperative wound healing of the titanium mesh exposed site, and the survival of expanded flap were recorded. The scar of the head incision and the appearance of head were followed up.  Results  Among the patients in this group, the expanders of 7 were placed in the temporal region, while the other 6 were placed at the top. The 11 patients were treated with advanced expanded flap, while the other 2 patients were treated with pedicled expanded flap. The head wounds of patients in this group successfully healed with retaining of the titanium mesh. The wound was healed after dressing change in 1 patient with necrosis at the tip of the expanded flap. The expanded flaps of 12 patients survived after transfer. Patients in this group were followed up for 12 months after surgery, the exposed titanium meshes were retained, the incisions healed well with the scars concealed, the hair on the scalp grew well, and the appearance of head was comparatively good.  Conclusions  Using expanded flap in the repair of the wounds with exposed titanium mesh after cranioplasty with titanium mesh can effectively cover the wound and retain the titanium mesh, achieving good function and appearance.
