目的：比较间接鼻咽镜下低温等离子射频消融术、鼻内镜辅助经口低温等离子消融术及鼻内镜经口电动吸引切割术治疗儿童腺样体肥大的临床疗效。方法选择行腺样体切除术180例患儿，随机分为 A、B、C 共3组，每组60例患儿。A 组采用间接鼻咽镜下低温等离子射频消融术、B 组采用鼻内镜辅助经口低温等离子消融术、C 组采用鼻内镜经口电动吸引切割术。比较3组术前准备时间、手术时间、术中出血量、术后疼痛时间及并发症等情况。结果 A 组术前准备时间最短，与其他2组比较差异均有统计学意义（P 均＜0．01）；A、B 组手术时间均短于 C 组（P 均＜0．01）、术中出血量亦少于 C 组（P 均＜0．01）；3组术后疼痛比较差异无统计学意义（P ＞0．05）。结论与鼻内镜辅助经口低温等离子消融术及鼻内镜经口电动吸引切割术比较，间接鼻咽镜下低温等离子消融术治疗儿童腺样体肥大，具有术前准备简单、手术时间短、出血量少、不增加术后疼痛等优点。“,”Objective To compare the clinical efficacy among indirect nasopharyngoscope-guided ra-diofrequency coblation,transoral endoscopy-guided radiofrequency coblation and transoral power-assisted endo-scopic adenoidectomy in treating the pediatric adenoid hypertrophy.Methods A total of 1 80 children diag-nosed with adenoidal hypertrophy were enrolled and divided into groups A,B and C (n =60 for each group). In group A,patients underwent indirect nasopharyngoscope-guided radiofrequency coblation,transoral endosco-py-guided radiofrequency coblation in group B and transoral power-assisted endoscopic adenoidectomy in group C.Preoperative preparation time,operation time,intraoperative hemorrhage volume,postoperative pain dura-tion and postoperative complications were statistically compared among three groups.Results Preoperative preparation time in group A was significantly shorter than that in groups B and C(both P <0.01 ).In groups A and B,the operation time was considerably shorter and intraoperative hemorrhage volume was significantly less than those in group C(all P 0.05).Conclusions Compared with transoral endoscopy-guided radio-frequency coblation and transoral power-assisted endoscopic adenoidectomy,indirect nasopharyngoscope-guided radiofrequency coblation is preferentially recommended in treating pediatric adenoid hypertrophy due to simpler preoperative preparation,shorter operation time,less intraoperative bleeding and less postoperative pain.
