Lateral views of tympanic bulla after removing the caudal and lateral aspects of the bulla
Figure 9A. Note a greenish epithelial remnant in the rostral compartment of the cavity, which must be removed entirely without damaging the maleus and promontory areas (labeled).
Figure 9B. Excellent exposure of the completely evacuated tympanic cavity is achieved with the described subtotal bulla osteotomy technique.
