摘要：Objective:Unilateral mimicking bilateral benign paroxysmal positional vertigo (umb-BPPV) was attrib-uted to inappropriate head positioning during testing of the posterior canal.Despite its inclusion in the Diagnostic criteria for the classification of vestibular disorders of the Bárány Society,the clinical char-acteristics and treatment responsiveness of this BPPV subtype have not been intensively studied.Methods:Records of patients with BPPV seen at a single outpatient dizziness clinic during the years 2000-2020 were reviewed.Eighty seven patients with umb-BPPV and 86 random patients with posterior canal BPPV (p-BPPV) were retrieved.Their demographics and BPPV characteristics were analyzed.Results:Patients' and BPPV characteristics were similar in umb-and p-BPPV except for the prevalence of males in the umb-BPPV group.No differences were found between treatment responsiveness and re-currences in both groups.The recurrence rate of umb-BPPV was not influenced by age,gender,BPPV side,duration of symptoms or treatment responsiveness during the first attack.Conclusions:In accordance with our hypothesis about mixed canalo-and cupulolithiasis as the under-lying mechanism of umb-BPPV,patients did not differ in characteristics and treatment responsiveness from p-BPPV patients.Recognition of umb-BPPV is important since inappropriate treatment can cause an unnecessary delay in therapy success.
