The broken heart sign, also known as the Y sign in older otorhinolaryngology literature , describes the appearances of incudomalleolar disarticulation.

This sign is identified on CT in the coronal plane, being formed by the widening of the incudomalleolar joint and lateral displacement of the short process of the incus relative to the head of the malleus .
