It has long been believed that sound waves, when introduced primarily by way of the round window, should vibrate the cochlear partition as well as when introduced primarily by the oval window. Theoretically, when all else is equal, hearing should be normal when sound enters the cochlea by either of the two windows, provided they have identical transformer mechanisms. This theoretical conclusion has heretofore been based upon anatomic and experimental studies, but there appear to be no previous reports of actual living examples that would serve to prove this conclusion.The aim of this paper will be to present the findings in a case of accidental roundwindow columella, which would seem to show that previous conclusions based only upon experimental evidence are indeed correct when applied to the living human subject.Wever and Lawrence1 have reviewed the historic literature, much of which is nonEnglish, to form a
