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 AND MATERIALS
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.
