title: Reflux laryngitis: an update, 2009-2012.
abstract: OBJECTIVE
  The importance of laryngopharyngeal reflux (LPR) is acknowledged widely. However, controversy remains regarding pathophysiology, diagnosis, and treatment. This review addresses current literature from late 2009 through the first half of 2012 and complements our previous review of literature from 2006 through the middle of 2009. Both reviews highlight controversies and current research.
  
  
  RESULTS
  Although controversies have not been resolved fully, additional research has expanded approaches to diagnosis and treatment of LPR. Recent studies shed additional light on pathophysiology. New imaging techniques have been introduced and they prove particularly useful in assessing LPR. Research has improved the understanding of the value of selected acid measurement techniques. The efficacy of treatment remains controversial.
  
  
  CONCLUSIONS
  LPR clearly is an important entity. However, disagreements persist regarding optimal diagnosis techniques, criteria of normalcy, and treatment efficacy. Additional studies are encouraged to further our understanding of pathophysiology, diagnosis, treatment, and the long-term effects of LPR and LPR treatment.
