Evaluation of Adding Lidocaine to Dexamethasone in Intra-tympanic Injection for Management of Tinnitus

Summary

Importance; Tinnitus is a heterogeneous diagnosis that may occur alone, in the presence of hearing loss or as a component of other disorders and can be quite disabling. Intratympanic injections of medications recently proved to have role in management of tinnitus. The investigators report on our experience with the use of intratympanic injection of Lidocaine as local anesthetic which potentiate the action of dexthamesasone in treatment of tinnitus without adding potential risks of inner ear Objective; to describe the effect of Lidocaine as local anesthetic may potentiate the action of dexthamesasone intratympanic injection in treatment of tinnitus without adding potential risks of inner ear Design, Setting, participants ; For this single tertiary center( Tanta University Hospital ) prospective case series, the investigators included 44 patients divided into two groups (A and B) 22 patients in each group suffering from tinnitus between March 2015 and October 2015 Intervention; Under local anesthesia 22 patients were subjected to intratympanic injection with combined Lidocaine 2% and dexamethasone with ratio (1:1), in the group A, and 22 patients in the other group B were subjected to intratympanic injection with dexamethasone only , this process was repeated 3 times for 3 successive weeks. Main Outcome and Measures; the primary outcome is self-reported significant improve in tinnitus in group A more in group B without adding significant damage of inner ear
