Microwave Ablation for the Removal of Benign Lesion of Nasal Cavity: “How I Do It”

Abstract

Background Isolated benign lesions of the nasal cavity are commonly seen in the rhinology clinic; their treatment using various therapies has been explored in several studies. Methods In this retrospective study, isolated lesions of the nasal cavity were removed from 47 patients using microwave ablation (MWA) with a 2450-MHz cooled MWA antenna and sent for histological examination. Results The most commonly involved site was the nasal septum (n = 21, 44.7%), followed by the inferior turbinate (n = 12, 25.5%), bulla ethmoidalis (n = 9, 19.1%), and uncinate process (n = 5, 10.6%). The most common pathology was hemangioma (n = 36, 76.6%), followed by nasal polyp (n = 9, 19.1%) and squamous papilloma (n = 2, 4.3%). All lesions were removed endoscopically using MWA in patients administered local anesthesia. The total duration of ablation was 5 to 10 minutes, with an average duration of 7.3 ± 2.6 minutes. Follow-up at 6 months revealed no severe complications, including no cases of recurrent epistaxis, septal perforation, or synechiae of the nasal cavity. Conclusions The advantages of MWA are its short ablation time and minimal complications. This was demonstrated in our study in which a single session of MWA was sufficient to excise the isolated lesion while providing hemostasis. Most of the patients well tolerated the procedure, which could be performed using local anesthesia in the outpatient setting.
