title: What is the relationship between chronic sinus disease and isolated nasal septal deviation?
abstract: OBJECTIVE
  The aim of this retrospective study is to examine the role of isolated nasal septal deviation (NSD) in the pathogenesis of chronic rhinosinusitis (CRS).
  
  
  METHODS
  The interaction between isolated NSD and chronic sinus disease were retrospectively evaluated in 1452 patients. Out of 1452 patients, 152 patients were included in the study. Patients with anatomical variants other than NSD were excluded from the study. Patients with NSD were enrolled in the study group and patients without NSD were enrolled in the control group.
  
  
  RESULTS
  There was no statistically significant difference between NSD group and non-NSD group with respect to the CRS.
  
  
  CONCLUSIONS
  The mild to moderate degree of NSD was not a risk factor for chronic sinus disease. Only gross deviation of the nasal septum itself is a risk factor for the development of CRS.
  
  
  CONCLUSIONS
  Excluding the subjects with ostiomeatal anatomic variations has differentiated this study from the previously reported researches (isolated NSD).
