<p<Abstract</p< <p<Background</p< <p<Vestibular neuritis (VN) is commonly diagnosed by demonstration of unilateral vestibular failure, as unilateral loss of caloric response. As this test reflects the function of the superior part of the vestibular nerve only, cases of pure inferior nerve neuritis will be lost.</p< <p<Case presentations</p< <p<We describe three patients with symptoms suggestive of VN, but normal calorics. All 3 had unilateral loss of vestibular evoked myogenic potential. A slight, asymptomatic position dependent nystagmus, with the pathological ear down, was observed.</p< <p<Conclusion</p< <p<We believe that these patients suffer from pure inferior nerve vestibular neuritis.</p< Ausführliche Beschreibung
