A canal wall up mastoidectomy is one of the types of mastoidectomies that can be performed. This involves exenteration of the mastoid air cells with preservation of the posterior wall of the external auditory canal, creating a mastoid bowl or cavity.

This procedure includes removal of Koerner’s septum, which then allows the surgically created cavity (mastoid bowl) to communicate with the antrum and epitympanum.
