To assess factors predicting vestibular neuritis (VN) prognosis at an early stage. Retrospective chart review. University hospital. Sixty-five patients with VN, between 2014 and 2018. Bithermal caloric test, rotatory chair test, subjective visual horizontal and vertical, cervical visual myogenic evoked potential test, and visual head impulse test (vHIT). Hospitalization duration. The mean hospitalization duration was 4.6 ± 1.4 days. Mean caloric weakness was 65.5 ± 20.6%. For the vHIT, gain in both anterior and horizontal semicircular canal (SCC) was statistically significantly different between the lesion and intact sides (p < 0.001). Backward conditional regression analysis revealed that a higher degree of spontaneous nystagmus (SN) (EXP[B] = 1.104, 95% confidence interval [CI] = 1.012-1.204, p = 0.026), and a lower caloric paresis (CP) value (EXP(B) = 1.033, 95% CI = 1.000-1.075, p = 0.047) were associated with 5 days or more of hospitalization. The cut-off value of SN was 12.05 degrees/s for increased hospital stay. Four weeks after discharge from hospital, five patients (8.9%) had persistent SN, and 19 (33.9%) and 28 (50.0%) had a positive HIT and nystagmus during head-shaking, respectively. Patients with persistent nystagmus at 1 month had more severe initial SN (p < 0.05). Only the degree of SN at the initial evaluation affected both the hospitalization period and the bed-side examination results at 1 month after discharge in patients with VN.

UI	MeSH Term	Description	Entries
D009759	Nystagmus, Pathologic	Involuntary movements of the eye that are divided into two types, jerk and pendular. Jerk nystagmus has a slow phase in one direction followed by a corrective fast phase in the opposite direction, and is usually caused by central or peripheral vestibular dysfunction. Pendular nystagmus features oscillations that are of equal velocity in both directions and this condition is often associated with visual loss early in life.

D002150	Caloric Tests	Elicitation of a rotatory nystagmus by stimulating the semicircular canals with water or air which is above or below body temperature. In warm caloric stimulation a rotatory nystagmus is developed toward the side of the stimulated ear; in cold, away from the stimulated side. Absence of nystagmus indicates the labyrinth is not functioning.	Barany Test,Barany's Test,Baranys Test,Caloric Test,Test, Barany,Test, Barany's,Test, Caloric,Tests, Caloric

D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.

D020338	Vestibular Neuronitis	Idiopathic inflammation of the VESTIBULAR NERVE, characterized clinically by the acute or subacute onset of VERTIGO; NAUSEA; and imbalance. The COCHLEAR NERVE is typically spared and HEARING LOSS and TINNITUS do not usually occur. Symptoms usually resolve over a period of days to weeks.
