Objectives: To investigate the clinical outcome of autogenous dermis combined with local flap transplantation in the treatment of titanium mesh exposure after cranioplasty. Methods: We studied a total of 8 patients with titanium mesh exposure after cranioplasty. After debridement of the head wound, the autogenous dermal tissue from the lateral thigh was transplanted to the surface of titanium mesh, and the local skin flap was then applied after suturing and fixation to repair the wound on the surface of the dermis. To repair the lateral thigh dermal tissue area, a local skin flap was obtained, and a blade thick skin graft was used. Results: Both dermal tissue and local skin flap survived. In the meanwhile, the donor skin area of the lateral thigh healed well, with only slight scar hyperplasia, and the titanium mesh was preserved. There was no recurrence after 6 months of follow-up. Conclusions: The application of autogenous dermis combined with local skin flap to repair titanium mesh exposure can effectively avoid skin flap necrosis, potential re-exposure of titanium mesh, sub-flap effusion, infection, and other problems. This method has an ideal effect, has easy access to materials, and reduces patients' economic burden. It is worth popularizing.

Objective To evaluate the clinical application of damage control surgery (DCS) in patients with sacrococcygeal deep decubitus ulcers complicated by sepsis. Methods We conducted a 3-year retrospective clinical study of 32 patients with deep sacrococcygeal bedsores and sepsis admitted from January 2018 to January 2021. According to the concept of DCS, the wound was temporarily closed with vacuum sealing drainage after primary debridement, and a local rhomboid flap was designed to repair the wound in the second stage. Finally, the clinical therapeutic effect was observed. Results Twenty-nine patients were treated with skin flap translocation and were cured clinically. Specifically, the skin flap survived in 27 of the 29 patients after the first translocation attempt (success rate of 93.1%). One patient developed incisional dehiscence, and one patient developed a hydrocele under the skin flap. Conclusions Application of DCS in patients with sacrococcygeal deep decubitus ulcers complicated by sepsis improves the therapeutic success rate and reduces the risks of the operation and complication rate. It has unique advantages and is worthy of clinical promotion.
