Paroxysmal Positional Vertigo

In 1949, Harold Schuknecht completed his residency in John Lindsay’s Otolaryngology Department at the University of Chicago and stayed first as a clinical instructor and then as an assistant professor. Schuknecht reviewed the temporal bone specimens from the patient reported by his mentor, John Lindsay, and from patients reported by Charles Hallpike and colleagues and was struck by the similarity in the pathologic changes. He concluded that in each case damage to the labyrinth resulted from occlusion of the anterior vestibular artery. Schuknecht believed that the delayed positional vertigo that occurred in these cases must have originated from the posterior semicircular canal. He reasoned that with degeneration of the superior vestibular labyrinth, otoconia would be released from the otolithic membrane of the utricular macule and that, in certain positions of the head, the otoconia would respond to gravity and thereby activate the cupula of the posterior semicircular canal.
