Tinnitus is the feeling of sound in the ear(s) or head, without external physical origin [1]. The otologic and non-otologic factors may contribute to tinnitus; however, the cause of tinnitus is unknown in approximately 30% of cases [2,3]. The most common type of tinnitus is subjective tinnitus, in which the sound can be perceived merely by the patient [2]. The tinnitus prevalence of in different studies varies according to reasons such as the exact definition of tinnitus, data collection method, etc [4].
