    1. TINNITUS AHMED ALARFAJ

    2. SUBJECTIVE TINNITUS: perception of sound in the absence of any acoustic, electrical, or external stimulation, more common than objective tinnitus, typically associated with a high frequency hearing loss, most common is 3000-5000Hz. OBJECTIVE TINNITUS: perception of sound caused by an internal body sound or vibration may be exacerbated with a conductive hearing loss.

    3. PATHOPHYSIOLOGY: is largely unknown; however, current tinnitus models center around subcortical auditory pathways rather than cochlear dysfunction

    4. DIFFERENTIAL DIAGNOSIS OF SUBJECTIVE TINNITUS Hearing Loss and Otologic Disorders Character of Dizziness: Retrocochlear Lesions (Acoustic Neuromas) Meniere Disease

    5. DIFFERENTIAL DIAGNOSIS OF SUBJECTIVE TINNITUS Medications Aspirin/NSAIDs Hypertensive Agents Aminoglycosides Numerous medications have been reported to have the potential to cause tinnitus

    6. DIFFERENTIAL DIAGNOSIS OF SUBJECTIVE TINNITUS Trauma Head Injuries (Whiplash Loud Noise Exposure Barotrauma Systemic Diseases Hypertension Depression and Anxiety Neurologic Disease (Multiple Sclerosis, Brainstem Stroke)

    7. VASCULAR CAUSES/ PULSATILE TINNITUS Benign Intracranial Hypertension Syndrome: Arteriovenous Malformations (AVM): Arterial Bruits and Venous Hums: Hypertension: Vascular Tumors

    8. MECHANICAL CAUSES Patulous Eustachian Tube: Palatal Myoclonus: Tensor Tympani Syndrome:

    9. MANAGEMENT OF SUBJECTIVE TINNITUS Conservative Management Hearing Aids Maskers
