Treatment of hard-to-heal wound after huge scalp tumor resection and reconstruction: a case report.

Introduction and importance: Free skin flap transplantation and titanium mesh reconstruction can effectively repair the scalp and skull defects caused by massive scalp tumour resection. Postoperative flap infection is a common complication. Due to the presence of titanium mesh, once infection occurs, a second operation is required to remove the titanium mesh, which brings a great physical and economic burden to the patient. Case presentation: In this case of postoperative infection, the authors used a conservative treatment based on dressing change, preserved the titanium mesh and flap, avoided secondary surgery, and successfully controlled the infection. Clinical discussion: The treatment strategy is mainly divided into three steps: the first stage is to control infection, the authors use complexed iodine to repeatedly disinfect wounds, subcutaneous dead space, exposed titanium mesh, and antibiotic treatment for bacterial culture results; the second stage is to promote granulation growth, After infection control, the authors remove old granulation after each wound disinfection, and then instill fibroblast growth factor to promote subcutaneous granulation growth to fill dead space, and also provide a base platform for epidermal growth; the third stage is mainly epidermal healing, Change the dressing every day to observe the growth of the epidermis. Conclusion: This case suggests that conservative treatment strategy based on dressing change is also a potential treatment option for postoperative infection of the flap with exposure of the titanium plate.
