In Reply.—It is a privilege to respond to Morris's communication concerning the state-of-the-art article on perilymphatic fistulas. His statements are clear and accurate. The diagnostic difficulties concerning perilymphatic fistulas are the catalysts for interest in, and investigation of, this topic. They are also the reasons that my colleagues and I embarked on our histopathologic temporal bone studies. With these studies, we, in effect, test the sensitivity and specificity of the diagnostic criteria that were detailed in the article. Our studies have continued since its writing, and I am pleased to report that the results thus far are still highly positive. However, the study is ongoing; therefore, we cannot express our final conclusions. We hope to be able to do this within the next year.
