Ossicular chain disruption (temporal bone fracture)


Longitudinal temporal bone fractures are more common than the transverse type. Conductive hearing loss in can be due to middle ear hemorrhage, or as in this case due to ossicular chain disruption. In any case of temporal bone fracture, ossicular joint alignments should be assessed. The ice cream cone sign is helpful in determining whether the incudomalleolar articulation is normal.
