Hereby we introduce a simply and novel surgery classification for endoscopic approached to middle ear cholesteatoma.
We classified middle ear cholesteatoma into four types. Type Ⅰ: attic retraction pocket; Type Ⅱ: cholesteatoma limited in the attic or endoscopic can confirm to clean up mastoid cholesteatoma lesions; type Ⅲ: cholesteatoma not limited in the attic and endoscopic cannot confirm to clean up mastoid cholesteatoma lesions; type Ⅳ: extensive involvement of mastoid cavity cholesteatoma lesions and/or have a potential risk of complications. In addition, there are two special types of middle ear cholesteatoma: Inadequate ear canal “difficult external auditory canal” and congenital cholesteatoma in children.
Our classification for middle ear cholesteatoma can very easy and convenient to choose surgical strategy for excision middle ear cholesteatoma.
