Surgical Result of Resection of Benign Neoplasm on the External Auditory Canal Using Transcanal Endoscopic Ear Surgery

Abstract

Various benign neoplasms such as osteoma, cholesteatoma, and cartilaginous choristoma can occur in the external auditory canal. The treatment method for these benign neoplasms is surgical excision. Previously, surgery had been performed using a microscope, but recently, a transcanal endoscopic ear surgery (TEES) method has been attempted. As a surgical method, it provides a better surgical view, enables rapid recovery and reduces pain through a minimally invasive approach. In this article, we introduce this endoscopic removal surgical method for benign neoplasms of the external auditory canal and the usefulness of the method.
