Interactive Radiology Case Reports :: Congenital hearing loss explained in adulthood. Computed tomography of the temporal bone in hemifacial microsomia. A case report.

Click 46 year old male patient with hemifacial microsomia. Axial computed tomography images of the temporal bone (native, slice thickness 1mm, 120kv/120mAs) demonstrating stenosis of the right external auditory channel, a soft tissue mass in front of the right tympanic membrane, hypoplasia and missing pneumatization of the of the right mastoid bone and a reduced diameter of the right internal carotid canal.

Click 46 year old male patient with hemifacial microsomia. Coronar computed tomography images of the temporal bone (native, slice thickness 1mm, 120kv/120mAs) demonstrating stenosis of the right external auditory channel, a soft tissue mass in front of the right tympanic membrane, hypoplasia and missing pneumatization of the of the right mastoid bone and a reduced diameter of the right internal carotid canal. Additionally there is partial fusion of the malleolus and incus.
