The efficacy of using a CO₂ laser for treating papilloma of the bilateral external auditory canals

Abstract

We herein report the case of a 29-year-old woman complaining of a 3-year history of both ears itching. The local findings revealed papilloma-like masses in the bilateral entrances to the external auditory meatus. We performed a biopsy, and the histopathological diagnosis was squamous papilloma. We performed surgery using a CO₂ laser for intractable vulgaris papilloma that developed in entrance to the external auditory meatus. Five months after the surgery, the symptoms were improved, and the tumor had flattened and disappeared. Given the outcomes of the present case, a CO₂ laser may therefore be effective for treating vulgaris papilloma in the external auditory meatus.
