![]() ![]() Tinnitus can occur as a result of certain abnormalities affecting the outer ear, the middle ear, the inner ear, the eighth cranial nerve or the brain. Tinnitus often becomes more noticeable at night and may, in many individuals, cause trouble with sleeping. For most people, tinnitus is less bothersome during the day when they are surrounded by noise related to their job or activities. It is one of the three symptoms of Meniere's disease. Tinnitus regularly accompanies such disorders as presbycusis, noise-induced hearing loss and otosclerosis. Objective tinnitus is not only heard by the individual, but may also be heard by others. This is by far the most common type of tinnitus. Subjective tinnitus is perceived by the individual only, and cannot be heard by anyone else. There are basically two types of tinnitus: subjective tinnitus and objective tinnitus. The mechanism and pathophysiology of tinnitus remains obscure. The condition must be present for at least 6 months. A single indication or complaint of tinnitus is not sufficient for diagnostic purposes. Diagnostic StandardÄiagnosis by a qualified medical practitioner and/or clinical/licensed/certified/registered audiologist is required. Tinnitus is defined as the perception of a sound in one or both ears or in the head when it does not arise from a stimulus in the environment. Signs and symptoms are generally expected to persist despite medical attention, although they may wax and wane over the 6-month period and thereafter. For VAC purposes, "chronic" means that the condition has existed for at least 6 months. Please note: Entitlement should be granted for a chronic condition only. The Tinnitus Entitlement Eligibility Guideline will apply to claims where the 2006 edition of the Table of Disabilities would apply.
