Video Nasoendoscopic-Assisted Transoral Adenoidectomy with the PEAK PlasmaBlade: A Preliminary Report of a Case Series.

. The primary objective for this study is to evaluate the advantages, disadvantages, surgical applicability, and outcome of the pulsed electron avalanche knife (PEAK) PlasmaBlade in transoral adenoidectomy under direct visualization using video nasoendoscopy. . In this series, six cases of adenoid hypertrophy showing varying clinical presentations in relation to its clinical course were surgically treated using a PEAK PlasmaBlade. Before and after surgery, all patients underwent nasal endoscopy to define the grading of hypertrophic adenoids and postoperative outcome. Pure tone audiometry and tympanometry tests were carried out to investigate the change in middle and inner ear functions. . The mean follow-up period was 23.8 months. Postoperatively, symptoms of otitis media with effusion were all relieved with closure of the air-bone gap (6/6). Other relevant ear complaints like tinnitus were resolved (1/1) and aural fullness disappeared in 87.5% of ears (7/8). Nasal obstruction (2/2) and postnasal drip (2/2) were improved after surgery. . Based on this preliminary report of a case series in a limited sample size, we suggest that using the transoral PEAK PlasmaBlade for adenoidectomy guided by video nasoendoscopy is a safe and feasible surgical technique, allowing remarkable outcomes by providing precise tissue removal, effective hemostasis, and painless postoperative recovery.
