The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Information provided by (Responsible Party):
Berthold Langguth, MD, Ph.D., University of Regensburg
  Purpose
Transcranial Magnetic Stimulation is used to modulate both the auditory neural pathways contributing to the perception of phantom sounds, and the regulatory neural network responsible for the generation of the individual amount of suffering caused by chronic tinnitus.

Condition Intervention
Chronic Tinnitus Device: Medial Frontal rTMS Double-Cone-Coil Device: Left DLPFC Butterfly Coil

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Effectiveness of Repetitive Transcranial Magnetic Stimulation (rTMS) With Double-Cone-Coil in Patients With Chronic Tinnitus (Ti-CDC)

Detailed Description:
Tinnitus is the phantom auditory perception of sound in the absence of an external or internal acoustic stimulus. It is a frequent problem which can interfere significantly with the ability to lead a normal life. Treatment remains difficult. Most available therapies focus on habituation rather than treating the cause. Tinnitus has been shown to be generated in the brain, as a result of functional reorganization of auditory neural pathways and tonotopic maps in the central auditory system. Low-frequency rTMS applied to the temporoparietal areas has been investigated for the treatment of hyperexcitability disorders such as auditory hallucinations and tinnitus. Pilot data indicate that taking into account affective components of the multiple overlapping neural networks responsible for the generation of a bothersome subjective tinnitus might enhance the efficacy of Repetitive Transcranial Magnetic Stimulation (rTMS) treatment in chronic tinnitus. A newly developed coil, the so-called double cone coil will be examined with regard to feasibility, safety and clinical efficacy in patients suffering from chronic tinnitus in a controlled pilot trial.
