Abstract

Imaging evaluation of the temporal bone often is neglected at the acute phase in patients with head trauma due to the urgent need to evaluate the brain. It should nonetheless be an integral part of this evaluation by the addition of thin dedicated CT images. Knowledge of the mechanisms of traumatic injuries combined to multiplanar reconstructions of the acquisition volume lead to accurate depiction of temporal bone injuries, including lesions of ossicles and footplate, structures measuring 2 or 3 mm. This comprehensive work-up will then allow prompt optimal ENT management and may improve the functional outcome.
