  • 3.  การรักษาการสมดุลย์ของการทรงตัวต้อง อาศัย visual system Proprioception  vestibular system
  • 4. Vertigo Illusionor hallucination of movement Vestibular system
  • 5. Vertigo History taking  Character of disorientation  Time course of vertigo , duration  Precipitating factors  Associated symptoms : hearing loss , tinnitus , nausea , vomiting , diplopia , CNS symptoms  Predisposing symptoms : general condition, trauma , drugs
  • 6. Vertigo Physical examination  ENT examination  CNS examination  Vestibular system examination :  Unterberger test  Caloric test  Dix-Hallpike maneuver  Evaluation of pathologic nystagmus
  • 7. Vertigo Investigation  Audiometry  ABR : Auditory Brainstem Response  ENG : Electronystagmography  Others : CBC,U/A,FBS,electrolyte,cholesterol, triglyceride,TFT,VDRL,CT scan ,MRI
  • 8. Peripheral Central 1.Onset sudden insidious 2.Pattern episodic continuous 3.Sensation frequent infrequent of rotation 4.Severity often intense seldom intense 5.Duration min.,hr. mo. to yr.
  • 9. Peripheral Central 6.Influence of marked slight or none head movement 7.Syncope never rare 8.Convulsion never rare 9.Tinnitus common rare 10.Deafness common rare
  • 10. Peripheral Central 11.Spontaneous may be may be nystagmus present present 12.Type of horizontal horizontal, nystagmus vertical 13.Other CNS rare common involvement
  • 11. Peripheral Cause of Vertigo BPPV Meniere’s disease Sudden hearing loss Vestibular neuritis Labyrinthitis
  • 12. BPPV Benign paroxysmal positional vertigo The most common vestibular disorder Age range 11-84 yr. Mean age at onset 54 yr Cupulolithiasis Canalithiasis
  • 13. BPPV Signs and Symptoms Vertigo and nystagmus  Latency of onset , usually 2-6 sec.  Short duration , usually less than 30 sec.  Reversibility  Fatigability Nausea , vomiting Dix-Hallpike maneuver
  • 14. BPPV Cause  Idiopathic  Trauma  Otitismedia  Vestibular neuritis  Meniere’s disease  Otosclerosis
  • 15. BPPV Cause  Sudden SNHL  CNS disease  Vertebral basilar insufficiency  Acoustic neuroma
  • 16. BPPV Treatment  Reassurance  Medication : minor transquilizer  Vestibular rehabilitation Repositioning maneuver  Surgery
  • 17. Meniere’s disease Idiopathic endolymphatic hydrop Signs and symptoms  Episodic vertigo lasting min to hr.  Fluctuating hearing loss  Tinnitus , fullness
  • 18. Meniere’s disease Audiogram : low tone hearing loss ABR ENG Radiography
  • 19. Meniere’s disease Treatment  Vasodilator  Cinnarizine , Dramamine  K-sparing diuretic drug  Stellate ganglion block  Intratympanic gentamicin therapy  Vestibular neurectomy
  • 20. Sudden hearing loss Hearing loss : hr or day Vertigo Tinnitus Others : headache , URI symptoms Nystagmus Tuning fork Audiogram : unilateral SNHL
  • 21. Sudden hearing loss Cause  Known cause : Syphilis, Meniere’s disease,multiple sclerosis , acoustic neuroma  Unknown : เชื่อว่าเกิดจากvirus,ความผิดปกติของหลอด เลือด autoimmune disease, labyrinthine membrane rupture ( LMR)
  • 22. Sudden hearing loss Treatment  Bed rest  Repeat audiogram  Steroid  Vasodilator  Heparin
  • 23. Vestibular neuritis Vertigo เป็นทันทีทนใดและเป็นอยู่นาน ั Spontaneous nystagmus มักมีไข้หวัดนำามาก่อน มักเดินเซข้างทีมี lesion ่ Audiogram : normal Caloric test : canal paresis or nonresponsive
  • 24. Vestibular neuritis Treatment  Rest  Dramamine , diazepam  Steroid  Physical therapy : Cawthorne-Cooksey exercise
  • 25. Labyrinthitis Virus : mump, measles, Herpes Bacteria : syphilis , OM ,meningitis  TB more often a complication of Tubercuolus meningitis than of Tuberculous otitis media.  Syphilis : congenital , acquire Fluctuating episodes of hearing loss and vertigo
  • 26. Acoustic neuroma Acoustic schwannoma Schwann cell tumor of vestibular part of CN VIII มักเกิด บริเวณ Internal acoustic canal แล้วยื่นเข้าไปบริเวณ CP angle Initially,slowly progressive hearing loss and tinnitus . Postural imbalance or disequilibrium.
  • 27. Acoustic neuroma Once the lesion compress the brainstem and vestibulocerebellum ,central compensation becomes impaired : vertigo , ataxia. Audiogram : unilateral SNHL ABR Caloric test : hypofunction MRI Treatment : surgery, radiation
  • 28. Central cause of vertigo 1.Vertebrobasilar insufficiency  Elderly  Atherosclerosis  Vertigo  Nausea,vomiting  Ataxia  Visual illusion ,visual field defect, diplopia, headache
