Abstract：
OBJECTIVE: The aim of this study was to investigate the feasibility of intranasal endoscopic microwave ablation (MWA) on the management of postoperative ethmoid sinus mucoceles.
METHODS: The patients with postoperative ethmoid sinus mucoceles were ablated through intranasal endoscopic MWA. Postoperative pain intensity was measured via visual analogue scale (VAS), post-operative complications were recorded.
RESULTS: Of the 26 patients with unilateral postoperative ethmoid sinus mucoceles, the mucoceles were diagnosed 3 to 11 years with average time of time of 6.9 ± 2.7 years after endoscopic ethmoidectomy. The ipsilateral middle turbinate was present and intact in 24 patients and partially resected during the original surgery in the remaining 2. There were adhesions in the middle meatus in one case. All 26 patients were successfully treated with the intranasal endoscopic ablation technique in outpatient. The ablation time was 6 to 11 min, with an average duration of 6.84 ± 1.27 min. The mean VAS pain score was 2.41 ± 1.22. There were no perioperative complications reported in this series. No evidence of recurrence was observed in any patients during follow-up periods.
CONCLUSIONS: The present study demonstrates the safety and efficacy of intranasal endoscopic MWA in the office. The procedure is well tolerated by patients with low complication rates. Thus, it is alternative to conventional endonasal endoscopic marsupialization for treatment of postsurgical ethmoid sinus mucoceles.

摘要：
目的：本研究的目的是探讨经鼻内镜微波消融（MWA）治疗筛窦黏液囊肿的可行性。
方法：术后筛窦黏液囊肿患者经鼻内镜MWA消融。术后疼痛强度通过视觉模拟评分法(VAS)测量,记录术后并发症。
结果：在26例单侧筛窦黏液囊肿术后，粘液囊肿诊断为3~11年,平均时间为内镜筛窦切除术后6.9±2.7年.24例患者存在同侧中鼻甲且完整，其余2例患者在原始手术中部分切除。1例中耳道有粘连。所有26例患者均在门诊患者中使用鼻内镜消融技术成功治疗。消融时间为6至11分钟，平均持续时间为6.84±1.27分钟。平均VAS疼痛评分为2.41±1.22。本系列报告无围手术期并发症。在随访期间，任何患者均未观察到复发的证据。
结论：本研究证明了经鼻内镜MWA在办公室的安全性和有效性。并发症发生率低的患者对该手术的耐受性良好。因此，它是传统的鼻内镜有袋化治疗筛窦黏液囊肿的替代方法。
