Summary

This study aimed to identify the prevalence of normal variations of temporal bone anatomy on high-resolution CT imaging and discuss their clinical importance

Conditions

  • Temporal Bone Abnormalities

Interventions

RADIATION

CT

Patients with unilateral ear pathology will be randomly assigned to do CT temporal bone, The presence of five variants was determined. These variants were: a high dehiscent jugular bulb, an anteriorly located sigmoid sinus, a deep sinus tympani, an enlarged cochlear aqueduct, and an enlarged internal auditory meatus (IAM). A GE LightSpeed 16, four-slice, helical CT scanner (Fairfield, Connecticut, USA) was used for all patients. The scan parameters were as follows: 1 mm slices, smart Ma (50-250 Ma), 120 kV, 0.8-second rotation time, 0.562:1 pitch factor, and 5.62 mm rotation speed. All scans covered an area from 1 cm inferior to the mastoid tip to 1 cm superior to the petrous temporal bone.
