Reflect soft tissue from the tympanic bulla
Figure 5. Soft tissue has been reflected and pried away from the lateral face of the tympanic bulla with a Freer elevator. A rongeurs is used to create a notch in the ventrolateral floor of the osseous EAM. This maneuver helps free edges of epithelium lining the osseous EAM so the lining can be removed completely in one piece.
