“…Affected individuals often describe it as kind of ringing, hissing, or buzzing, most often continuous, sometimes intermittent. Tinnitus affects a considerable proportion of the general population, with a minority experiencing considerable distress (Hazell, 1990; Feldmann, 1998; Baguley and McFerran, 2002; Lockwood et al, 2002; Eggermont and Roberts, 2004; Shargorodsky et al, 2010). Often, but not always, tinnitus is associated with a certain measure of hearing loss mostly of the upper part of the range of hearing (Henry et al, 1999).…”

Objectives: In tinnitus, several brain regions seem to be structurally altered, including the medial partition of Heschl's gyrus (mHG), the site of the primary auditory cortex. The mHG is smaller in tinnitus patients than in healthy controls. The corpus callosum (CC) is the main interhemispheric commissure of the brain connecting the auditory areas of the left and the right hemisphere. Here, we investigate whether tinnitus status is associated with CC volume. Methods: The midsagittal cross-sectional area of the CC was examined in tinnitus patients and healthy controls in which an examination of the mHG had been carried out earlier. The CC was extracted and segmented into subregions which were defined according to the most common CC morphometry schemes introduced by Witelson (1989) and Hofer and Frahm (2006). Results: For both CC segmentation schemes, the CC posterior midbody was smaller in male patients than in male healthy controls and the isthmus, the anterior midbody, and the genou were larger in female patients than in female controls. With CC size normalized relative to mHG volume, the normalized CC splenium was larger in male patients than male controls and the normalized CC splenium, the isthmus and the genou were larger in female patients than female controls. Normalized CC segment size expresses callosal interconnectivity relative to auditory cortex volume. Conclusion: It may be argued that the predominant function of the CC is excitatory. The stronger callosal interconnectivity in tinnitus patients, compared to healthy controls, may facilitate the emergence and maintenance of a positive feedback loop between tinnitus generators located in the two hemispheres.

Abstract-Tinnitus, or "ringing in the ears," affects 10%-15% of adults; cases can be problematic and require lifelong management. Many people who have experienced traumatic brain injury (TBI) also experience tinnitus. We developed Progressive Tinnitus Management (PTM), which uses education and counseling to help patients learn how to self-manage their reactions to tinnitus. We adapted PTM by delivering the intervention via telephone and by adding cognitive-behavioral therapy. A pilot study was conducted to evaluate the feasibility and potential efficacy of this approach for individuals with and without TBI. Participants with clinically significant tinnitus were recruited into three groups: probable symptomatic mild TBI (n = 15), moderate to severe TBI (n = 9), and no symptomatic TBI (n = 12). Participants received telephone counseling (six sessions over 6 months) by an audiologist and a psychologist. Questionnaires were completed at baseline, 12 weeks, and 24 weeks. All groups showed trends reflecting improvement in self-perceived functional limitations due to tinnitus. A follow-up randomized clinical study is underway.Key words: blast injury, clinical trial, cognitive-behavioral therapy, education, hearing disorders, military Veterans, rehabilitation, telehealth, tinnitus, traumatic brain injury.Abbreviations: CBT = cognitive-behavioral therapy, ESS = Epworth Sleepiness Scale, HADS = Hospital Anxiety and Depression Scale, ICF = informed consent form, IED = improvised explosive device, IRB = institutional review board, LOC = loss of consciousness, m-sTBI = moderate to severe traumatic brain injury (group), mTBI = probable symptomatic mild traumatic brain injury (group), NCRAR = National Center for Rehabilitative Auditory Research, noTBI = no symptomatic traumatic brain injury (group), OIF = Operation Iraqi Freedom, PC-PTSD =

“…Tinnitus is defined as the perception of an internal sound in the absence of an external stimulus (Lockwood, Salvi, & Burkard, 2002) and is a widespread phenomenon in the general population (Shargorodsky et al, 2010). Chronic tinnitus is associated with a number of psychological health problems, such as irritability, anxiety, insomnia, and depression (Langguth, 2011).…”
