Comparison of laser cauterization with general anesthesia microscopically supported laryngoscope and conventional microinstrumentally-supported laryngoscope resection in the treatment of vocal cord polyps
Objective To study the application of laser cauterization with general anesthesia microscopically supported laryngoscope in the treatment of vocal cord polyps.Methods The prospective study selected 90 patients with vocal cord polypectomy admitted to Bayannur Hospital from March 2019 to May 2022,and the patients were randomly divided into an observation group(47 cases)and a control group(43 cases)according to the envelope method.In the control group,23 males and 20 females,aged(50.12±1.85)years,were treated with conventional microinstrumentally-supported laryngoscope resection.In the observation group,25 males and 22 females,aged(49.75±2.18)years,were treated with laser cauterization with general anesthesia microscopically supported laryngoscope.The surgical results,Grade of Roughness,Breathiness,Asthenia,and Strain(GRBAS),Voice Handicap Index(VHI)score,Generic Quality of Life Inventory-74(GQOL-74)score,and complications were compared between the two groups.t test and x2 test were used.Results The overall response rate of the observation group was 93.62％(44/47),and there was no statistically significant difference compared with that of the control group[86.05％(37/43)](x2=1.430,P=0.232).After surgery,the total hoarseness[(1.39±0.41)in the observation group and(1.61±0.34)in the control group],rough sound[(1.36±0.50)in the observation group and(1.42±0.52)in the control group],breath sound[(0.91±0.52)in the observation group and(0.94±0.53)in the control group],and VHI score[(11.48±7.36)points in the observation group and(12.04±7.52)points in the control group]in both groups were lower than those before surgery,and the postoperative total hoarseness of the observation group was lower than that of the control group[(1.39±0.41)vs.(1.61±0.34)],with statistically significant differences(all P＜0.05).The scores of physical health[(20.14±4.02)points],mental health[(22.57± 4.86)points],material life[(13.54±3.57)points],and social function[(16.78±3.71)points]of the observation group were higher than those of the control group[(16.47±3.46)points,(19.67± 3.76)points,(11.49±3.24)points,and(13.47±3.16)points],with statistically significant differences(t=4.621,3.145,2.843,and 4.535;all P＜0.05).The incidence of complications of the observation group was 8.51％(4/47),which was lower than that of the control group[25.58％(11/43)],with a statistically significant difference(x2=4.712,P=0.030).Conclusion Compared with conventional microinstrumentally-supported laryngoscope resection,patients with vocal cord polyps treated by laser cauterization with general anesthesia microscopically supported laryngoscope have lower total hoarseness,higher postoperative quality of life,and fewer complications,which is worthy of use in clinical practice.
