It is now five years since stapes mobilization has been established as a safe and practical procedure for restoring the hearing in otosclerotic deafness. I described my approach to the stapes through the external auditory canal in 1952.1 Since then, many otologists in America and abroad have used this technique in an estimated 25,000 cases of otosclerosis.

Working only through the external auditory canal with an ordinary ear speculum, one removes all of the bone of the posterior canal wall hiding the incus and stapes. With this exposure, the entire long process of the incus, the incudostapedial footplate, facial nerve, and round window can all be seen clearly and in great detail
