Volumetric Changes in the Bony External Auditory Canal in Unilateral Chronic Otitis Media

摘要

Background and ObjectivesPneumatization of air cells in the mastoid bone is decreased in chronic otitis media (COM). A decrease in the size of the external auditory canal (EAC) is also found frequently in patients with COM, but this has been little studied. We compared the size of affected bony EACs and the contralateral side in patients with single-side COM using high-resolution computed tomography.
