Abstract

Malleus fracture is a rare condition. Usually, the handle of the malleus is involved, and we do not find reports in the literature of this condition in the bilateral presentation. It is present as sudden conductive hearing loss commonly after digital manipulation of the external auditory canal. The diagnosis is based principally on clinical examination by otomicroscopy and audiometry. Cone-beam computed tomography emerging as a powerful tool in the field of otolaryngology, especially for explorations of paranasal sinuses and temporal bone, due to imaging with a high resolution and few artifacts with lower dose radiation in comparison with multislice computed tomography.
