[ACOUSTIC CR®-NEUROMODULATION -- FIRST EXPERIENCIES IN HUNGARY WITH A NOVEL METHOD IN THE THERAPY OF CHRONIC SUBJECTIVE TINNITUS].Ideggyogy Sz. 2015 May 30; 68(5-6):189-98.IS
Acoustic CR®-neuromodulation is a novel patented method for the therapy of chronic subjective tinnitus and has been tested in Hungary, as one of the first European countries introducing this procedure. It can be used for the treatment of monaural or binaural tonal tinnitus. Suitability of patients for this therapy was assessed by the help of an appropriate set of criteria. Aim of our study was to analyze 6-month therapy and related measurement data of patients first treated with this method in Hungary and evaluate the results.
27 outpatients (20 males, seven females) with a minimum of 6-month long history of subjective tinnitus were assessed (four detected on the right side, six on the left side, 17 on both sides) who were treated for six months by Acoustic CR®-neuromodulation. On 44 treated ears (21 right, 23 left), changes of tinnitus frequency and loudness were measured and analysed, using Visual Analogue Scale (VAS) loudness/annoyance/pitch scores and Tinnitus Handicap Inventory tests, which were performed at defined intervals during the treatment period.
During this 6-month treatment period, significant decrease was detected in tinnitus frequency and loudness by tinnitometry (irrespective of the affected side), and an improvement in VAS annoyance/pitch scores and THI test results. VAS loudness did not show any significant changes.
Acoustic CR®-neuromodulation therapy may be a useful treatment of subjective chronic tinnitus, but its efficacy should be proved in controlled clinical trials.
