Retrospective Study on Application of High-negative Pressure Drainage Bottle in Postoperative Removal of Maxillofacial Tumors
Objective:To retrospectively analyze the complications and economic benefits of using high-negative pressure drainage bottles versus low-negative pressure drainage drums in patients undergoing maxillofacial tumor re-section.Methods:A retrospective analysis was conducted on patients with maxillofacial tumors between December 1,2021,and May 31,2022.Based on the treatment received,123 patients were divided into two groups:the high pressure negative pressure wound therapy(HP-NPWT)group(≤-15 kPa,n=79)and the low pressure negative pressure wound therapy(LP-NPWT)group(≥5.2 kPa,n=44).Clinical outcome data,including postoperative complications,length of hospital stay,and surgical and treatment costs,were analyzed.Results:Among 44 patients in the low-pressure group,17 patients had wound infections,resulting in a wound infection rate of 38.64％.In con-trast,among 79 patients in the high-pressure drainage group,only 3 patients had infections,yielding a wound infec-tion rate of 3.8％(P＜0.001).Regarding flap transplantation,the incidence of flap necrosis in the low-pressure group was 9.09％,while no cases of flap necrosis occurred in the high-pressure group(P＜0.05).Conclusion:The incidence of complications in patients undergoing maxillofacial tumor resection surgery with high-negative pressure suction drainage is significantly lower compared to low-negative pressure suction drainage.
