BACKGROUND: The aim of this article was to study the application value of a provocative test for diagnosis and reduction of self-developed SRM-IV superior semicircular canal in frequent superior semicircular canal benign paroxysmal positional vertigo (BPPV).
METHODS: For the study 2500 cases of patients with highly suspected BPPV from January 2013 to January 2016 were selected. After the posterior semicircular canal lesion and lateral semicircular canal lesion were excluded through many repeats of Dix-Hallpike Test and Roll Test, 375 cases (15.00%) were considered as superior semicircular canal lesion. The Dix-Hallpike Test and SRM-IV superior semicircular canal BPPV provocative test were conducted successively until typical and vertical downward nystagmus occurred. The diagnostic value and therapeutic effects of both two methods were compared.
RESULTS: The diagnosis positive rate of SRM-IV BPPV Test was significantly increased, mean test times and time of each test were decreased, and effective rate of BPPV reduction was significantly increased. The differences had statistical significance (P<0.05).
CONCLUSIONS: The SRM-IV superior semicircular canal BPPV provocative test had better diagnosis and reduction value in frequent superior semicircular canal BPPV.
