AN IMPROVED RETRACTOR FOR THE SO-CALLED RADICAL OPERATION ON THE MIDDLE EAR.
HUGO FREY, M.D.Assistant to Professor Pollitzer.VIENNA.The instrument shown in the illustration has proved very useful to me in making a complete opening into the tympanic cavity—the so-called radical operation. It facilitates especially the removal of the posterior wall of the bony meatus and the outer attic wall. The curve of the hook is made with reference to the anatomic configuration of the parts, so that it retains the membranous meatus close to the anterior walls of the bony canal; the lateral projections holding back the adjacent parts of the auricle.In using the retractor, the handle should be kept in the direction of the patient's upper lip and somewhat higher than the front part of the instrument.
