Abstract

Abstract: 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 resection. 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 contrast, among 79 patients in the high-pressure drainage group, only 3 patients had infections, yielding a wound infection 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.

Key words: maxillofacial tumor, negative pressure wound therapy, level of negative pressure, surgical prognosis
