The provider revises a previous complete or modified radical mastoidectomy by performing a radical mastoidectomy. This involves excision of the ossicles, eustachian tube and middle ear mucosa, granulation tissue, and cholesteatoma. The provider also reconstructs the ear canal if needed. He performs the procedure because the prior procedure failed to produce a dry ear, which results in recurrent otitis media accompanied by accumulation of pus, eardrum perforation, and recurrent or residual hearing loss.
