Abstract:
Objective:To analyze the application effects and safety of continuous negative pressure drainage devices in postoperative drainage of congenital microtia reconstruction of auricle.Methods:A retrospective study was conducted, including 1 211 patients with congenital microtia treated at the Plastic Surgery Hospital of Chinese Academy of Medical Sciences and Peking Union Medical College from January 2018 to August 2021. All patients underwent auricular reconstruction surgery and were divided into two groups based on the type of negative pressure drainage device used. The study group consisted of 624 patients [315 males and 309 females, aged 6-24 (15.1±2.2) years], while the control group consisted of 587 patients [286 males and 301 females, aged 5-23 (14.7±2.3) years]. The study group used a novel negative pressure drainage ball, while the control group used a conventional negative pressure syringe for drainage. The preoperative and postoperative 1, 7 days scores of the modified Yale preoperative anxiety scale (mYPAS) and the quality of life scores postoperative 3 days (including functional activity, self-image, psychological health, satisfaction and pain) were compared between the two groups. All patients were followed up at 4, 8, 12, and 16 weeks postoperatively to compare the surgical scar area between the two groups. The incidence of adverse reactions within 12 weeks after surgery in two groups were recorded.Results:There was no significant difference in preoperative mYPAS scores between the two groups ( P=0.897). The mYPAS scores at 1 and 7 days after surgery were lower than the preoperative scores in both groups (all P<0.05), and the study group had significantly lower mYPAS scores at all time points than those of the control group (all P<0.001). The study group had higher scores in functional activity, self-image, psychological health, and satisfaction than those of the control group (all P<0.001), and a lower pain score than that of the control group ( P<0.001). Follow-up at 4, 8, 12, and 16 weeks showed that the surgical scar area was significantly smaller in the study group at all time points than in the control group (all P<0.001). The incidence of adverse reactions within 12 weeks after surgery was 9.0% (56/624) in the study group, which was lower than the 19.4% (114/587) in the control group ( P<0.001). Conclusion:The use of continuous negative pressure drainage devices in congenital microtia reconstruction of auricle is more effective and can reduce the incidence of postoperative adverse reactions.
