Auditory Pathology (ear infection) 0001
The absence of a right periotic bone in this Beluga Whale (Delphinapterus leucas) may be due to non-development or a lytic process. The normal left ear of this animal argues against but does not rule out a congenital defect. The absence of the periotic bone, the pitted and corrupted right tympanic, the extensive calcified adhesions, and dense granular material in the peribullar sinus suggest protracted infection.
