Comparison of application effects of low temperature plasma ablation and electrosurgical coagulation on OSAHS
Objective To analyze and compare the application effects of low temperature plasma ablation and electrosurgical coagulation on obstructive sleep apnea-hypopnea syndrome(OSAHS).Methods The clinical data of 92 patients with OSAHS who underwent surgical treatment in the hospital were retrospectively analyzed.Among the patients,48 cases underwent low temperature plasma ablation combined with uvulopalatopharyngoplasty(UPPP)(observation group)and 44 cases received electrosurgical coagulation and UPPP therapy(control group).The perioperative indicators,postoperative pain degree[Visual Analogue Scale(VAS)],postoperative complications and clinical efficacy were recorded in the two groups,and the changes in polysomnography(PSG)parameters[apnea hypopnea index(AHI),lowest blood oxygen saturation(LSaO2)]of the two groups were compared before surgery and at 6 months after surgery.Results There were no statistically significant differences in the time of postoperative wound pseudomembrane shedding,complete shedding time of pseudomembrane and incidence rates of postoperative complications between the two groups(P>0.05).The surgical time and intraoperative blood loss of the observation group were shorter or less than those of the control group(P<0.05).The VAS score of the two groups was gradually decreased after surgery(P<0.05),and the VAS score after surgery in observation the group was lower than that in control group(P<0.05).There were 42 cases in observation group and 39 cases in control group with examination data at 12 months after surgery,and there were 16 cases and 11 cases with examination data at 24 months after surgery.The clinical efficacy at 6 months,12 months and 24 months after surgery was significantly higher in observation group than that in control group(P<0.05).At 6 months after surgery,the AHI of both groups was reduced compared with that before surgery(P<0.05),and the AHI in observation group was lower compared to control group after surgery(P<0.05).The LSaO2 was increased compared with that before surgery(P<0.05),and the LSaO2 in observation group was higher than that in control group after surgery(P<0.05).Conclusion Low temperature plasma ablation can be used for tongue root ablation during treatment,and has good short-term efficacy and long-term efficacy in the treatment of moderate-to-severe OSAHS,and has small injury in the surgical area and high clinical application value.
