Can migraine damage the inner ear?
The sudden left-sided deafness likely resulted from ischemia, possibly due to migraine-associated vasospasm. Presumably, the right ear suffered only minimal damage when the patient was 50 years old, but this damage later led to the development of delayed endolymphatic hydrops on the right. Otolithic crises are thought to result from pressure changes across the utricular macule. We speculate that loss of hair cells in the utricular macule resulted from a collapse of the utricular membrane onto the macule.
A 40-minute ABO followed by surgical damage control improved survival in this animal model of uncontrolled hemorrhagic shock caused by abdominal trauma. ABO could be considered for the management of severe abdominal trauma.
