title: An unusual anatomical variation of the superior turbinate: a case report.
abstract: BACKGROUND
  The only anatomical variation of the superior turbinate defined in the literature is concha bullosa. Determination of anatomical variations of the intranasal structures is important to perform safe endoscopic sinus surgery and avoid complications.
  
  
  METHODS
  We report a case of an unusual anatomical variation of the superior turbinate in a 55-year-old Turkish man with nasal obstruction and headache.
  
  
  CONCLUSIONS
  Anatomical variations of superior turbinate are very rare. Variations of intranasal structures can easily be detected with coronal plane paranasal sinus computed tomography.
