Abstract:
Objective:To investigate the factors associated with complications following the implantation of external-expansion devices with an injection port.Methods:A retrospective study was conducted, including 68 patients who underwent expansion device implantation at the Department of Plastic Surgery, Sun Yat-sen Memorial Hospital of Sun Yat-sen University, from January 2019 to May 2022 and the patients experienced postoperative complications (case group). Additionally, 195 patients who underwent the same procedure during the same period but did not experience complications were selected as control group, following a 1∶3 ratio. Preoperatively, different shapes and sizes of expansion devices were chosen according to the lesion location and area. Observational indicators included admission diagnosis, preoperative white blood cell count, preoperative hemoglobin count, gender, age, implantation site of the expander, season of admission, and duration of postoperative drainage tube placement. Univariate and multivariate logistic regression analyses were used to analyze factors associated with postoperative complications.Results:Univariate logistic regression analysis revealed that implantation at the trunk ( OR=0.439, 95% CI: 0.207-0.901, P=0.028), admission diagnosis of microtia ( OR=4.155, 95% CI: 1.735-10.206, P=0.001), and admission season from April to September ( OR=3.269, 95% CI: 1.819-6.073, P<0.001) were associated with complications following expansion device implantation. Multivariate logistic regression analysis showed that admission season from April to September ( OR=3.272, 95% CI: 1.796-6.156, P<0.001) was a significant factor associated with postoperative complications. Conclusion:Implantation site at the trunk, admission diagnosed with microtia, and admission season from April to September are the factors associated with complications following expansion device implantation.
