THIS subject has been little discussed in the recent literature, and now that otologists have had the opportunity of reviewing statistical reports of the end results of fenestration operations, it becomes apparent that they are definitely in need of such a discussion. The more experienced surgeons are agreed that when cases are well selected a large majority of the patients will have their hearing improved to the practical level in consequence of the fenestration operation. The improvement occurs usually within three to six weeks. The percentage of cases in which hearing is so improved varies, according to the reports, from 70 to as high as 90 per cent. These figures are strikingly impressive. Whatever the actual percentage of early good results may be, ultimate failures are of such frequency that the question of revision becomes one of major importance.
