A Case of External Auditory Canal Stenosis due to Paget's Disease of Temporal Bone / 대한이비인후과학회지

Paget's disease is a localized bone disorder that affects widespread areas of skeleton characterized by increased bone remodeling. It is a chronic, progressive disease of unknown etiology. The pathologic process is initiated by hyperactive osteoclastic bone resorption followed by a compensatory increase in the osteoblastic new bone formation. New pagetic bones are disorganized and more susceptible to deformities and fractures. Paget's disease can affect one or multiple bones in the systemic skeleton, including the temporal bone. We experienced a case of chronic otitis media combined with an external auditory canal stenosis due to Paget's disease of the temporal bone. We report clinicopathologic features of this rare case.
