“…Tinnitus can be present in patients with or without hearing loss, and its cause may be multifactorial. Although it is well known that the prevalence of tinnitus increases in subjects with hearing loss, such as presbycusis [Zagólski, 2006;Ferreira et al, 2009;Terao et al, 2011], chronic acoustic trauma [Mazurek et al, 2010;Dawes et al, 2014], hereditary hearing loss, or other hearing disorders [König et al, 2006;Roberts et al, 2010;Sheppard et al, 2014;Ralli et al, 2016;Ryan and Bauer, 2016;Shore et al, 2016], tinnitus can also be present in the absence of hearing loss [Schaette and McAlpine, 2011;Modh et al, 2014;Plack et al, 2014] and can have its roots in other factors, such as somatic [Levine, 1999;Cacace, 2003;Shore et al, 2007;Dehmel et al, 2008;Simmons et al, 2008;Shore, 2011] and psychological dysfunctions [Belli et al, 2008;Langguth et al, 2011;Salviati et al, 2014].…”
