Research Progress of Traditional Chinese and Western Medicine on Residual Symptoms after Reduction of Benign Paroxysmal Positional Vertigo

Benign paroxysmal positional vertigo is one of the most common vestibular peripheral diseases, which is characterized by recurrent transient vertigo and characteristic nystagmus caused by changes in head position relative to gravity. The annual prevalence rate of BPPV is about 1.6%, accounting for 20.30% of vestibular vertigo, which is usually high after the age of 40, and the incidence shows an upward trend with age. At present, the common treatment methods in western medicine are otolith reduction and drug therapy. Manual reduction is a common and effective reduction method for the treatment of otolithiasis. However, many reports have confirmed that there are many residual symptoms such as dizziness and instability after reduction. Western medicine is often used to improve circulation, dilate blood vessels and other drugs for symptomatic treatment, such as betastine, ginkgo biloba extract, etc., often the efficacy is not good, and even depression, restlessness and other symptoms, seriously affecting the life and work of patients. Therefore, rapid and effective relief of residual symptoms in patients with BPPV after reduction has gradually become the focus of clinical research in recent years. This article reviews the research progress of traditional Chinese and western medicine on residual symptoms after BPPV reduction.
