RESUMO
Objective To investigate the clinical effect of low-temperature plasma radiofrequency with endoscopic laryngoscope in the treatment of adult patients with laryngeal papilloma.Methods From January 2014 to April 2018,60 adult patients with laryngeal papilloma in Zhuji Central Hospital were enrolled in this study.According to the treatment methods,they were divided into control group and observation group,with 30 cases in each group.The control group was treated with laryngoscope tweezers,and the observation group was treated by low temperature plasma radiofrequency with endoscopic laryngoscope.The operation time,intraoperative blood loss,hospitalization time and postoperative complications were recorded.The follow-up was performed on the first day after operation.The recurrence rate and average recurrence time were recorded.Results The average operation time in the observation group was (29.54 ± 4.52)min,which was significantly shorter than (38.85 ± 5.47)min in the control group (t =7.186,P =0.000).The intraoperative blood loss of the observation group was (1.24 ± 0.76) mL,which was significantly lower than (35.69 ± 5.88) mL of the control group (t =31.825,P =0.000).The length of hospital stay of the observation group was (3.83 ± 1.17) d,which was significantly shorter than (4.79 ± 1.47) d of the control group (t =2.798,P =0.006).The incidence rate of postoperative complication in the observation group was 3.33％ (1/30),which was significantly lower than 23.33％ in the control group (x2 =5.192,P =0.022).The mean duration of postoperative recurrence in observation group was (2.42 ± 0.57) months,which was significantly longer than (1.28 ± 0.36) months in the control group(t =9.261,P =0.000).The postoperative recurrenc.e rate of the observation group was 6.67 ％ (2/30),which was significantly lower than that of the control group [40.00 ％ (12/30),x2 =9.316,P =0.002].Conclusion Low temperature plasma radiofrequency with endoscopic laryngoscope in the treatment of adult patients with laryngeal papilloma has less trauma,and can extend the recurrence time,reduce the postoperative recurrence rate.
