title: Resolution of vocal fold polyps with conservative treatment.
abstract: OBJECTIVE
  Vocal fold polyp is generally thought to require surgical removal. However, a certain proportion of polyps resolve with conservative treatment. This study was performed to clarify the frequency of spontaneous resolution of vocal fold polyp and identify features associated with polyps that are likely to resolve without surgery.
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  A review of the medical records of patients diagnosed with vocal fold polyps in Tokyo Voice Center from January 2001 to December 2008.
  
  
  RESULTS
  Of 644 patients with the diagnosis of vocal fold polyp, 132 received conservative treatment, 433 were treated surgically, and 79 dropped out without attending for further consultation after the initial visit. Of those treated conservatively, 55 experienced complete resolution after a mean of 5.1 months of follow-up from the outset, and 29 showed lesion shrinkage after a mean of 4.1 months of follow-up. Polyps that resolved with conservative therapy were more likely than those that remained unchanged or enlarged to occur in women, be smaller, and have a shorter duration of symptoms. We could not determine the superiority of voice therapy.
  
  
  CONCLUSIONS
  At least 9.7% of vocal fold polyps might resolve without surgery. Conservative treatment should be considered as an option for selected patients with smaller and more recent-onset polyps.
