Surgical Treatment of Laryngeal Papillomatosis Using NBI

Objective: Multiple laryngeal papillomatosis has a high rate of recurrence after surgery. Narrowband imaging (NBI) is a novel optical enhancement technology used for the diagnosis. This is the first report to date to indicate the availability of the combination of laryngomicro surgery and videoendoscopic surgery for laryngeal papillomatosis using NBI technology.Method: The patients were 34-year-old and 30-year-old men. Both cases underwent surgery in another hospital. However, because of recurrence, they were subsequently referred to our department for further evaluation. Examination in our outpatient clinic revealed papilloma-like mucosal changes, and recurrent multiple laryngeal papillomatosis was diagnosed in both cases.Results: In laryngomicroscopic surgical findings, the presence of papillomas was confirmed by NBI, and the papillomas were removed using an XPS Micro Debrider and a CO2 laser. Using the NBI system, the border between the normal mucosa and the papillomas could be clearly identified, allo...
