title: [The assessment of sequential treatment for subjective and objective benign paroxysmal positional vertigo].
abstract: OBJECTIVE
  To compare the effectiveness of sequential treatment for subjective and objective benign paroxysmal positional vertigo(BPPV).
  
  
  METHODS
  The efficacy of sequential treatment for nineteen vertical semicircular canal S-BPPV patients(Group A) and forty-five vertical semicircular canal O-BPPV patients(Group B) who were admitted to our hospital between January 2014 and July 2015 was retrospectively analyzed and compared, treatment of five cases with horizontal semicircular canal S-BPPV was reported here as well.
  
  
  RESULTS
  The number of repositioning maneuver for Group A was 2 - 6 times (average: 4. 21±1. 18) while 2 - 3 times (average: 2. 29 ± 0. 46) for Group B. There was significant difference between the two groups(P<0. 01). The effective rate of initial treatment for Group A was 78. 9%(15/19) while 82. 2%(37/45)for Group B. After one weeks treatment, the effective rate for Group A changed to be 89. 5% (17/19)while 88. 9% (40/45) for Group B. Non-significant difference was found in the two groups neither in the initial nor one weeks treatment. On three months' follow-up, one in Group A and two in Group B relapsed, and they were cured after treated in the initial treatment. The recurrence for Group A was 5. 3%(1/19) while 4. 4%(2/45) for Group B and there was non-significant difference. The five cases with horizontal semicircular canal S-BPPV were completely free of disease after undergoing treatment.
  
  
  CONCLUSIONS
  The sequential treatment is effective for both vertical semicircular canal S-BPPV and vertical semicircular canal O-BPPV, but the former needs more repositioning maneuver times. The repositioning maneuver, combined with drug therapy and head-shake-in-supine-position method is recommended for horizontal semicircular canal S-BPPV.
