Significance of ENG and DPG in the vestibular function examination in patients suffering BPPV / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To detect the significance of the electronystagmography (ENG) and the dynamic posturography (DPG) in the vestibular function examination in patients suffering BPPV.@*METHOD@#Forty, 34 to 79 old vertigo patients were examined with DPG and ENG. DPG evaluation parameters includes sense organization test from vestibular sensory score, proprioception score, visual score, Romber's score and composite score. ENG examination include caloric test.@*RESULT@#Twenty-six out of 40 BPPV patients got abnormal caloric test results; 33 patients got DPG abnormality which led to a low vestibular perception scores. Twenty-four out of these patients got abnormal results in both caloric test and DPG, while in 9 patients that got normal caloric results came up with low vestibular perception scores, except for which there was no significant abnormality in SOT. Besides, the BPPV patients, compared with normal, got abnormal scores in caloric test of ENG and vestibular perception test of DPG (P < 0.05), if course of BPPV was over 12 months, higher abnormal degrees appeared (P < 0.05).@*CONCLUSION@#ENG and DPG are important methods in vestibular function tests, a comprehensive analysis of both is applied to value the severity of vestibular function in patients with BPPV and the duration of BPPV directly affects the vestibular function.

A systematic review of vasodilators for sudden sensorineural hearing loss / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To evaluate the efficacy and safety of vasodilators for sudden sensorineural hearing loss.@*METHOD@#Based on the principles and methods of Cocharne Systematic Reviews, we searched the cochrane central register of controlled trials, PubMed, Embase, ISI, the China biological medicine datebase, VIP, CNKI and Wangfang database. Randomized controlled trials about using vasodilators to treat sudden sensorineural hearing loss were included. Meta-analysis was performed for the results of homogeneous studies using RevMan software.@*RESULT@#Twenty eight randomized control trials met the inclusion criteria. Seven studies showed vasodilators was not more effective than placebo. From 14 studies comparing vasodilators with vasodilators and 9 studies comparing vasodilators with other drugs, no definite conclusion could be drawn.@*CONCLUSION@#The evidence currently available does not support the use of vasodilators in the treatment of sudden sensorineural hearing loss. Further randomized, double-blind, placebo-controlled trials are needed in order to define the efficacy and acceptability of vasodilators in the treatment of sudden sensorineural hearing loss.
