Abstract
OBJECTIVE: To evaluate the clinical value of lidocain in the treatment of tinnitus through three routes of administration (intravenous, intratympanic and acupoint injection) by analyzing literatures.
METHOD: Articles were collected through Hownet, Wanfang, VIP, Pubmed, SciVerse ScienceDirect, Springer and OVID, etc. The articles were strictly evaluated based on their quality. The Meta-analysis was performed to evaluate the outcomes by RevMan 5. 2 software.
RESULT: A total of 16 articles with 1203 patients were enrolled in the analysis. Their tinnitus history ranged from 7 hours to 20 years. Assessment methods include tinnitus loudness levels, severity scales and subjective feelings. None of articles refer to maintaining time, instead of "short-term", "short" and so on. A total of 133 cases received intravenous injection and the effective rate was 73.4% (98 cases). 50 cases and 332 cases received intratympanic and acupoint injection respectively and their effective rates were 74.0% and 87.7%, respectively. The effective rate ranged from 42.4% to 58.3% in control group. Meta-analysis results indicate that all three routes of lidocaine administrations are more effective than conventional methods (P < 0.05).
CONCLUSION: Different routes of lidocaine administration have a good but short time effects on the tinnitus control. It can effectively reduce the time of tinnitus habituation as a complementary treatment. But its value still needs further evaluation.
