Intratympanic Lidocaine as a Potent Remedy for Tinnitus in Sudden Sensorineural Hearing Loss: A Double-Blind, Randomized Clinical Trial.
Objective: This study evaluates intratympanic lidocaine's efficacy and safety for tinnitus relief in sudden sensorineural hearing loss (SSNHL) patients.
Methods: In a double-blind randomized controlled trial, 100 SSNHL patients with unilateral tinnitus received either intratympanic lidocaine or saline plus usual care. Treatment impact was assessed at 1 and 3 months using the Tinnitus Handicap Inventory, subjective visual analog scale, pure-tone audiometry.
Results: The lidocaine group demonstrated significant tinnitus relief according to the Tinnitus Handicap Inventory and visual analog scale, without pure-tone audiometry improvement or serious adverse events throughout the study period.
Conclusion: Intratympanic lidocaine provides a safe, efficacious treatment option for SSNHL tinnitus. Further studies should refine the dosage and delivery parameters because of SSNHL's heterogenous nature.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
