title: [Influence of nasal septal deviation on incidence of bilateral sinusitis].
abstract: OBJECTIVE
  To investigate the influence of nasal septal deviation on the incidence of bilateral sinusitis.
  
  
  METHODS
  Two thousand and seventy-four cases of nasal septal deviation with chronic sinusitis available from January 2006 to March 2012 were reviewed retrospectively.
  
  
  RESULTS
  Of these 2074 cases, 1 687 (81.3%) patients had sinusitis in narrow side and 1582 (76.3%) in wide side, the difference was statistically significant (P < 0.01) and the relative risk value in narrow side (1.4) was higher than wide side (0.7) associated with the incidence of sinusitis. There was significant difference (P < 0.05) between the two group counting datas analyzed by rank sum test, and the mean rank order in narrow side was 1656.396, significantly greater than wide side (1 612.184). The incidence of sinusitis in men was 50.6% (1049/2074), in women was 49.4% (1025/2074), and there was no significant difference between them. Deviating leftward was 1148 cases (55.4%), deviating rightward was 926 cases (44.6%), and the difference was statistically significant (P < 0.05). Anatomic variations in narrow side and wide side were uncinate process hypertrophy (7.0%, 27.0%), middle turbinate hypertrophy (7.8%,38.0%), ethmoidal bulla hypertrophy (26.2%, 39.0%), paradoxical middle turbinate (5.4%, 15.5%), hypertrophic inferior turbinate (52.9%, 67.0%) and mucosa pachynsis (0.5%, 2.8%), respectively.
  
  
  CONCLUSIONS
  Sinusitis incidence in narrow side is higher than wide side. There is no significant difference between the incidence of sinusitis in men and women. The majority of nasal septum deviate leftward. Higher incidence of sinusitis in wide side is the result of compensatory mechanism. Only septoplasty may not restore the normal venting function in nasal cavity. Hypertrophic inferior turbinate are closely correlated with sinusitis.
