Abstract:【Objective】 To explore the advantages of adenoidectomy cutting ablation under slow-temperature plasma radiofrequencyendoscope through nose and oral cavity combined approaches. 【Methods】 From June 2010 to October 2012, 72 cases of adenoidal hypertrophy patients were divided into two groups, endotoscpe incision suction through nose and oral cavity combined approaches electric adenoidectomy in 35 cases, endotoscpe in low-temperature plasma Radiofrequency through nose and oral cavity combined approaches adenoids cutting ablation in 37 cases, followed up for 6 months and were retrospectively analyzed. 【Results】 The endoscope through nose and oral cavity combined approaches electric cutting suction group, blood loss, surgical time-consuming, postoperative bleeding in 2 cases, postoperative pain response, nostrils area 3 cases of recurrence in the nasopharynx. endotoscpe through nose and oral cavity combined approaches adenoids of low-temperature plasma radiofrequency cutting ablation group, 2 to 5 mL of a trace amount of intraoperative bleeding, no case of bleeding after surgery without nasal packing, reactions were mild pain, no recurrence. 【Conclusion】 The endoscope through nose and oral cavity combined approaches in low temperature plasma radiofrequency the adenoids cutting ablation is easy to exposure, shorter operative time, intraoperative bleeding or a very small amount of bleeding, pain was mild, no recurrence, etc. is worthy of clinical.
