Clinical characteristics and repositioning efficacy analysis of posterior canal-benign paroxysmal positional vertigo-canalolithiasis and vertigo-cupulolithiasis patients.

Background: Currently, there is a ‌paucity of research‌ comparing the clinical characteristics and repositioning efficacy between ‌posterior canal-benign paroxysmal positional vertigo-canalolithiasis (PC-BPPV-ca)‌ and ‌posterior canal-benign paroxysmal positional vertigo-cupulolithiasis (PC-BPPV-cu)‌.

Aims/objectives: To observe the clinical characteristics and compare the efficacy of repositioning maneuvers between PC-BPPV-ca and PC-BPPV-cu patients.

Material And Methods: Clinical information of patients was collected.

Analysis of etiology and clinical features of spontaneous downbeat nystagmus: a retrospective study.

Objective: To investigate the topical diagnosis, possible etiology and mechanism of spontaneous downbeat nystagmus (sDBN) patients with dizziness/vertigo.

Methods: The clinical features of dizziness/vertigo patients accompanied with DBN were retrospectively reviewed in the Vertigo Center of our hospital from January 2018 to March 2021. The clinical features of dizziness/vertigo patients accompanied with DBN were reviewed.
