Abstract
To investigate the clinical characteristics of Benign Paroxysmal Positional Vertigo
(BPPV) in patients with vestibular neuritis (VN). Methods: Clinical data of of 236 patients diagnosed with VN
werecollected and divided based on occurrence of BPPV into the control group (without BPPV) and observation
group (with BPPV). The clinical characteristics and caloric test results of the two groups were analyzed. The
effectiveness of manual maneuvers in VN with BPPV was observed. The Dizziness Handicap Inventory (DHI)
was applied before treatment and on Days 10, 20, and 30 of treatment to analyze treatment effectiveness.
Results: Of the 236 VN cases studied, 23 cases developed BPPVwithin one month of disease onset. Of these,
18 cases were limited to the ipsilateral side of VN and 5 cases were limited to contralateral side of VN. In all, 20
cases were PC-BPPV and 3 were HC-BPPV. Five cases showed significant improvement in BPPV after 1
maneuver treatment; 10 cases showed improvement after 2 maneuver treatments; 8 cases showed improvement
after 3 maneuver treatments. The rate of abnormal caloric test results within the control group was 65.87% ,
which was significantly lower than the 86.96% within the observation group (P<0.05). There was no significant
difference between the two groups in the DHI scores obtained pre-treatment and on Day 10 of treatment. DHI
scores on Days 20 and 30 of treatment were significantly higher in the observation group than those in the control
group (P<0.05). Conclusion: VN is accompanied by BPPV in some patients. In VN patients with BPPV, the
incidence of abnormal caloric test results is relatively high, recovery is slow, and 2 or more manual maneuver
treatments are generally needed.
