Plate 8: Grippe Otitis, Infant (otitis influenzae ; myringitis bullosa hemorrhagica) One or more hemorrhagic blebs appear on the surface of the drum. They may be located in any quadrant of the tympanic membrane. They result from extravasation of blood between the outer and middle layers. When present in the postero-superior quadrant they may be mistaken for bulging. The malleus handle, Shrapnell's membrane and other portions of the drum are injected and reddened. These blebs should not be incised.
