This demonstrates the anatomic relationship of the normal ossicular chain. When it is disrupted, a severe conductive hearing loss results. Surgery is aimed at reestablishing the continuity of the conductive mechanism from the tympanic membrane to the oval window. This may require an interposition graft or prosthesis. This can generally be accomplished by lifting the tympanic membrane via a transcanal or other approach of the surgeon’s preference.
