Comparison of application effects between low-temperature plasma and conventional electric knife in removal of benign lesions of soft palate mucosa
Objective To compare the clinical effect of low-temperature plasma and conventional electric knife in the removal of benign lesions of soft palate mucosa.Methods 15 patients with benign lesions of soft palate mucosa who underwent low-temperature plasma resection were selected as the study group,and 15 patients with benign lesions of soft palate mucosa who underwent conventional electrosurgical resection were selected as the control group.The lesion area,operation time and intraoperative bleeding volume,visual analogue scale(VAS)score,recurrence of the disease within 6 months,postoperative secondary bleeding and hematoma were compared between the two groups.Results The lesion area,operation time and intraoperative bleeding volume were(6.65±2.61)cm2,(21.87±5.19)min and(16.47±4.14)ml in the study group,and(6.52±2.25)cm2,(22.00±5.14)min and(16.87±3.66)ml in the control group,respectively.There were no significant differences in lesion area,operation time and intraoperative bleeding volume between the two groups(P>0.05).The VAS scores at 1,3 and 5 days after operation in the study group were(3.87±1.13),(2.80±0.77)and(1.80±0.68)points,respectively,while those in the control group were(6.73±1.28),(5.60±1.06)and(3.20±1.86)points,respectively.The VAS scores of the two groups at 1,3 and 5 days after operation were gradually decreased,and the study group was significantly lower than the control group,the difference was significant(P<0.05).In the control group,there were 1 case(6.67%)of secondary hemorrhage on the traumatic surface(bleeding stopped after electrocoagulation of the bleeding point under local anesthesia)and 2 cases(13.33%)of hematoma of the soft palate(no respiratory and swallowing difficulties were caused,and the hematoma was gradually resorbed after a cold-flow diet and local ice packs).There was no secondary bleeding and soft palate hematoma in the study group.There was no difference in the incidence rate of secondary bleeding and soft palate hematoma between the two groups(P>0.05).Follow-up for 6 months showed no recurrence in both groups.Conclusion In the resection of soft palate mucosal lesions,the application of low-temperature plasma can significantly reduce the postoperative pain response and reduce the occurrence of secondary bleeding and hematoma,and the clinical effect is accurate.It can be used as the first choice in clinical practice if economic conditions permit.
