It is a well known fact in mastoid surgery, whether it be a fenestration, a simple or radical mastoidectomy, or the surgical removal of polyps of the ear canal, that the only way to keep the surgical field "spick and span" is by the use of intermittent or continuous suction and irrigation, a method which has finally displaced the old sponge-drying technic used years ago.
To perform this type of operation a considerable amount of time is sometimes required, and any modification which may bring a saving of time and instrument handling should be considered an improvement in this particular field of surgery.
