title: Benign paroxysmal positional vertigo secondary to laparoscopic surgery.
abstract: OBJECTIVE
  Benign paroxysmal positional vertigo is a common vestibular disorder and it may be idiopathic or secondary to some conditions such as surgery, but rare following laparoscopic surgery.
  
  
  METHODS
  We report two cases of benign paroxysmal positional vertigo secondary to laparoscopic surgery, one after laparoscopic cholecystectomy in a 51-year-old man and another following laparoscopic hysterectomy in a 60-year-old woman.
  
  
  RESULTS
  Both patients were treated successfully with manual or device-assisted canalith repositioning maneuvers, with no recurrence on the follow-up of 6 -18 months.
  
  
  CONCLUSIONS
  Benign paroxysmal positional vertigo is a rare but possible complication of laparoscopic surgery. Both manual and device-assisted repositioning maneuvers are effective treatments for this condition, with good efficacy and prognosis.
