- Abstract
- In most cases, sudden deafness results from viral infection, vascular occlusion or cochlear membrane rupture, but occasionally,
its central origin can not be excluded. Although a number of signs are theoretically plausible in patients with pontine infarction such
as facial weakness, lateral gaze palsy, Horner syndrome, limb dysmetria, crossed sensory loss or vertigo, isolated sudden deafness
is a very rare manifestation. When pontine infarction occurs, it is usually identified on T2-weighted and diffusion-weighted
magnetic resonance imaging (MRI). Early treatment with anticoagulant and antiplatelet agents leads to a more rapid resolution
of symptoms and preservation of existing brain function. Recently, the authors have experienced two cases of sudden hearing
loss caused by acute pontine infarction. Hence, we report two cases with a review of literature. (Korean J Otorhinolaryngol-
Head Neck Surg 2008;51:650-4)
