title: [Effect of posterior nasal neurectomy combined with the inferior turbinate surgery for Japanese cedar pollinosis].
abstract: BACKGROUND
  Up to 30% of the Japanese population suffers from Japanese cedar pollinosis, and some of these patients also have severe perennial allergies or other pollen allergies. Posterior nasal neurectomy has recently been reported as effective treatment for severe perennial allergic and intrinsic rhinitis. However, the efficacy of this surgery for seasonal allergic rhinitis has not been shown. In this study, the effectiveness of posterior nasal neurectomy combined with inferior turbinate surgery for patients with Japanese cedar pollinosis with concomitant intractable perennial allergies was evaluated with a questionnaire.
  
  
  METHODS
  Nine patients with Japanese cedar pollinosis, who also had perennial allergies, and undergone posterior nasal neurectomy combined with inferior turbinate surgery from April in 2005 to July in 2008, were enrolled. A numeric rating scale (NMR) was used to evaluate clinical symptoms in the pre- and post-surgery periods. The frequency of medication (oral administration and nasal spray) during the cedar pollinosis season was also evaluated.
  
  
  RESULTS
  The NMR scores for all nasal and eye symptoms during cedar pollinosis season were significantly reduced after the surgery. The frequency of medication during the season was dramatically decreased after surgery.
  
  
  CONCLUSIONS
  The present study demonstrates that posterior nasal neurectomy combined with inferior turbinate surgery is a highly effective treatment for Japanese cedar pollinosis. Since the Japanese cedar pollinosis season is limited to 2 to 3 months, such surgery is indicated for patients who suffer from severe perennial allergies and are also sensitized to some allergens such as Japanese cedar and ragweed pollen.
