AB Patients  with  osseous  dysplasias  of  the  temporal  bone,  notably,  fibrous  dysplasia,  Paget's  disease,  osteopetroses,  and  osteogenesis  imperfecta,  present  with  hearing  loss  and  external  auditory  canal  obstruction  that  result  in  infection,  lower  cranial  neuropathies,  and  temporal  bone  deformation.  Differentiation  among  these  entities  is  greatly  helped  by  using  coronal  and  axial  high-resolution  computed  tomography  (CT)  imaging  of  the  temporal  bone  and  skull  base.  Outer,  middle,  and  inner  ear  structures  are  detailed  and  foraminal  stenoses  are  identified.  Bone  mineralization  density  appearance  is  the  single  most  important  imaging  feature  to  secure  a  diagnosis.
