In dressing through the enlarged outer ear canal the cavity created by the radical operation for the cure of chronic middle-ear suppuration I have found the ear speculum with a handle very useful. The accompanying illustration shows a modified Boucheron ear speculum. The distal end is shortened and a handle is attached to the rim of the funnel. The end of the handle is hooklike and can be held either with the thumb and the second finger, or, with the second finger alone by bending the same, or, with the third or the fourth finger. In the latter instances some of the fingers are disengaged and can be used for other purposes. The length of the instrument is about 7.5 cm. (3 in.). The handle is about 1 cm. (% in.) wide.
