Abstract
Head tilt is characterized by a rotation of the median plane of the head along the axis of the body, resulting in one ear being held lower than the other. A head tilt often indicates a vestibular disorder and occurs as a result of the loss of antigravity muscle tone on one side of the neck. Head tilt must be differentiated from a head turn. This chapter covers diagnostic approach.

Transverse T2-weighted and T1-weighted contrast-enhanced MR images of a cat with left-sided otitis media/interna causing left-sided head tilt, facial nerve paralysis and Horner’s syndrome. On T2-weighted images, the left bulla contains tissue that is mostly hyperintense to neural tissue (arrow). The signal from the perilymph in the left inner ear (arrowhead) is reduced compared to the normal right inner ear. The contrast-enhanced image shows marked enhancement of the periphery of the left bulla (arrow) and left inner ear (arrowhead). © 2013 British Small Animal Veterinary Association
