Analysis of clinical efficacy of low-temperature plasma radiofrequency ablation under supportive laryngoscope in the treatment of early-stage glottic carcinoma
Objective To observe the effect of low-temperature plasma radiofrequency ablation under supportive laryngoscope in the treatment of patients with early-stage glottic carcinoma. Methods 65 patients with early-stage glottic carcinoma were divided into a control group (45 cases) and an observation group (20 cases) according to different surgical methods. Patients in the control group received routine surgical treatment,and patients in the observation group received low-temperature plasma radiofrequency ablation under supportive laryngoscope. Patients in both groups were compared in terms of surgical indicators (intraoperative blood loss,operation time and hospitalization time),mucosal recovery,visual analogue scale (VAS) score,incidence of complications,and improvement of vocal function (fundamental frequency perturbation,amplitude perturbation,and harmonic-to-noise ratio). Results The intraoperative blood loss of (10.28±0.86) ml in the observation group was less than (32.53±3.05) ml in the control group;the operation time and hospitalization time were (29.63±2.14) min and (8.18±0.78) d in the observation group,which were shorter than (61.24±4.55) min and (13.42±1.15) d in the control group;VAS score and mucosal repair score were (2.08±0.17) and (2.11±0.17) points in the observation group,which were lower than (3.19±0.34) and (3.68±0.34) points in the control group (P<0.05). The incidence of postoperative complications of 5.00％ in the observation group was lower than 31.11％ in the control group (P<0.05). After surgery,the fundamental frequency perturbations and amplitude perturbations were (1.14±0.08)％ and (4.02±0.36)％ in the observation group,which were lower than (1.31±0.11)％ and (4.31±0.40)％ in the control group;the harmonic-to-noise ratio of (21.92±2.05) dB in the observation group was higher than (20.03±1.86) dB in the control group (P<0.05). Conclusion In the treatment of early-stage glottic carcinoma patients,the implementation of low-temperature plasma radiofrequency ablation under supportive laryngoscopy can not only achieve good clinical treatment results,but also help reduce the incidence of postoperative complications and promote the recovery of vocal function. It is worthy of promotion.
