title: Study of relationship of concha bullosa to nasal septal deviation and sinusitis.
abstract: OBJECTIVE
  To study the etiological role of concha bollosa in deviated nasal septum (DNS) and sinusitis.
  
  
  METHODS
  In this retrospective study 419 consecutive CT scans of paranasal sinuses done between October 2005 and September 2007 were serially evaluated for the presence of concha, DNS and sinusitis.
  
  
  RESULTS
  Out of 419 CT scans evaluated, concha bullosa was present in 40.3% of patients. Among these, concha co-existent DNS was found in 87.5%, air column between DNS and concha was found in 88.5% and sinus disease was present in 69.2% of patients.
  
  
  CONCLUSIONS
  Presence of air column between DNS and concha excludes the etiological role of concha in DNS. Concha bullosa may predispose to sinusitis.
