2 The most scary thing in ent clinic is dizzy patient at the end of the day

3 Benign paroxysmal positional vertigo
History Pathology Management P/E Treatment

4 Benign Paroxysmal Positional Vertigo
1921 first described in by Bárány 1952, Dix and Hallpike reported this entity in a large group of patients. described the Dix-Hallpike maneuver recognized features of the nystagmus Latency directional characteristics brief duration Reversibility fatigability .

5 BPPV Schuknecht 1969 (Cupulolithiasis ) McClure
loose otoconia from the utricle PSCC McClure 1979 Canalithiasis mechanism

6 Benign paroxysmal positional vertigo
History Pathology Management P/E Treatment

7 Incidence 30% of peripheral vestibular disease 15 per 100,000 in Japan
64 per 100,000 in Minnesota. Twice Ménière's mean age fifth decades Increases with age. Women:men 1.6:1

8 Etiology Primary or idiopathic (50%–70%) Secondary (30%–50%)
Viral labyrinthitis (15%) Head trauma (10%) Ménière’s disease (5%) Migraines (< 5%) Inner ear surgery (< 1%)

9 BPPV: Pathophysiology
Degenerative debris from utricle (otoconia) Canalithiasis Theory floating freely in the endolymph Cupulolithiasis Theory Adhering to the cupula

15 ? PSCC PSCC Hangs down like the water trap in a drain pipe
Allowing the crystals to settle in the bottom of the canal.

17 History Sudden Seconds Severe vertigo Bouts of vertigo remissions
Chronic balance problems Worse in the morning

18 History Associated with change in head position.
rolling over or getting into bed assuming a supine position. arising from a bending position looking up to take an object off a shelf tilting the head back to shave turning rapidly.

History Pathology Management P/E Diagnosis Treatment

23 Test Results ENG limitation
Do not record the torsion Low frequency(0.003 Hz)* Lateral SCC LOC Rotational-chair & posturography have no role Imaging with CT scanning or MRI is unnecessary =

24 D/D Postural hypotension Drugs Cupula sensitive to gravity Fistula
anti-hypertensive drugs CV problems Drugs Cupula sensitive to gravity PAN-1 PAN-2 Heavy water Fistula

25 D/D History is virtually pathognomonic Only type of vertigo
Multiple times per day brief episodes NO auditory complaints No neurological

27 Treatment Patient education Medical Exercise Surgical

28 Patient education Inner ear disease Not CVA Not Cancer Recurrence

29 Medical Relieve of nausea Promethazine Prochlorperazine

30 Epley Maneuver Dr. John M. Epley 1980 * Canalilith Repositioning
Canalith debris  vestibule single treatment = 95% Remission Otolaryngol Head Neck Surg 88:599–605, 1980.

31 Epley Maneuver Reclined head hanging 45 degree turn

32 Epley Maneuver Rotate 45 degrees contralateral

33 Epley Maneuver Head and body rotated to 135 degrees from supine

34 Epley Maneuver Keep head turn and to sitting
Turn forward chin down 20 degrees

38 Sleep semi-recumbent for the next two nights

39 Semont Liberatory maneuver 1st rapid single treatment
83.96% one maneuver 92.68% two 4.22% recurrence Others less success, too violent

41 Brandt and Daroff exercises
Seated eyes closed Tilted laterally to precipitating position Lateral occiput resting Vertigo subsides Sit up for 30 sec Opposite head down position 30 sec Vertigo opposite (bilateral) maintain until resolves Every 3 hrs while awake, until 2 days free

42 Brandt-Daroff Exercises

43 Brandt and Daroff 98.5% relief 3-14 days Most 7-10 days 3% recurred
Non-responder had perilymph fistula 66 of 67

44 Brandt and Daroff

45 Surgical ? Section of singular nerve Canal occlusion
Vestibular nerve section Eliminate response from PSCC Candidates unrelenting symptoms from same ear, multiple recurrences

46 Singular Neurectomy Gacek* Anatomy
Nerve exits lateral IAC singular canal Courses inf. and post. to PSCC ampula Inf-post to round window niche *Ann Otol Rhinol Laryngol 83:596–605, 1974

47 Singular Neurectomy Published success 90%
Persistent symptoms if nerve not definitively found Complications Recurrent vertigo, SNHL Severe SNHL 5% Trauma, labyrinthitis Mild SNHL 20% Only attempted by experience surgeons

48 PSCC Occlusion Prevents flow of endolymph
Animal studies no effect on remaining vestibular organs Procedure Cortical mastoidectomy Identify and blue-line canal Open with pick Occlude canal Laser partitioning optional Pack canal, bone wax, dust, fascia covering

49 PSCC Occlusion Transient SNHL Mild SNHL persists 20%
Detected intraoperatively by ECog Recovers by 6-8 weeks Mild SNHL persists 20% Post-op dysequilibrium for a few days/weeks Average in-patient stay 4.5 days Recurrent vertigo rare, f/u limited PSCC occlusion vs. singular neurectomy

50 Horizontal canal BPPV 17% of cases Supine head lateral provocative
Cupulolithiasis > canalithiasis From reposition of PSCC for BPPV toward (geotropic) away from (ageotropic)

51 Horizontal canal BPPV Latency < 3 sec < 1 min duration
may beat toward or away from side of the cupula No fatigability 92% Side lying with the affected ear up for 12 h resolves much more quickly than PSCC-BPPV toward (geotropic) away from (ageotropic)

52 Superior canal BPPV Least common Dix-Hallpike positioning testing
Rt PSCC = Lt SSCC vice versa

71 BPV: Clinical Approach Examination

72 Dix-Hallpike Maneuver

73 Canalith repositioning maneuver for treatment of benign paroxysmal positional vertigo (BPPV) affecting the posterior canal. Panel 1 shows a patient with right posterior canal BPPV. The patient's head is turned to the right at the beginning of the canalith repositioning maneuver. The inset shows the location of the debris near the ampulla of the posterior canal. The diagram of the head in each inset shows the orientation from which the labyrinth is viewed. In panel 2, the patient is brought into the supine position with the head extended below the level of the gurney. The debris falls toward the common crus as the head is moved backward. In panel 3, the head is moved approximately 180 degrees to the left while keeping the neck extended with the head below the level of the gurney. Debris enters the common crus as the head is turned toward the contralateral side. In panel 4, the patient's head is further rotated to the left by rolling onto the left side until the patient's head faces down. Debris begins to enter the vestibule. In panel 5, the patient is brought back to the upright position. Debris collects in the vestibule. Illustration by David Rini.
