Abstract
A myringotomy tube is disclosed for transtympanic placement in an ear to ventilate the middle ear and relieve infection. The tube includes body with a bore that is angled to provide a view of portions of the middle ear that are not immediately in line with a longitudinal axis of the body. An extension member is attached to the body, and may be grasped by forceps to rotate the tube, and direct the line of view through the bore to different portions of the ear. Rotation of the body and its angled bore permits a panoramic view of the inner ear. The extension may also be grasped by forceps to extract the tube from the ear. Longer extensions, that protrude out of the external opening of the auditory canal, may be used for temporary placement and manual digital removal without requiring forceps.
