  2. 2. Objectives1.Define Vertigo2.Essential Clinical Evaluation of patients3.Common Vertiginous Syndromes4.Common Management strategies
  3. 3. Definition• Illusion of Movement (Rotatory & Postural)• Differentiate from • Light headedness, • Imbalance, • Visual phenomenon, • faintish-ness
  4. 4. Basic Sciences• Systems involved : • Vestibular • Ocular • Proprioception • Central Nervous System
  5. 5. Basic Sciences
  6. 6. Anatomy
  7. 7. Schematic drawing of the vestibular epithelium showingthe two cell types and the nerve connections made on each.
  8. 8. The position of the crista ampularis and cupula within a cross sectionof the ampulla of one semicircular canal. Also shown is the movement of the cupula and its embedded cilia during rotation first in one direction and then in the opposite direction.
  9. 9. Shearing force in vestibular organs. Upper diagram shows arrangement of cilia on a hair cell as seen from above; position of kinocilium indicated by larger dot. Dashed line indicates direction of effective shearing forces; forces at right angles are ineffective. Lower diagram shows section through hair cell along dashed line (upper diagram) with cilia at rest (center) and tilted right and left. Tilt toward kinocilium excites, tilt away deceases excitation.
  10. 10. Brainstem pathways forcontrol of eyemovements by the left horizontal semicircular canal.
