title: The effects of choanal atresia on development of the paranasal sinuses and turbinates.
abstract: OBJECTIVE
  The objective of this study was to evaluate the volume of paranasal sinuses (PNS) and turbinate in patients with unilateral choanal atresia (CA).
  
  
  METHODS
  Computed tomography images of PNS in 11 individuals with unilateral CA were evaluated retrospectively. Mucosal thickness and volume of the maxillary, frontal and sphenoidal sinuses were determined, in addition to the volume of the middle and inferior turbinate. The unaffected nasal side of patients was used as a control group for the measurements. The results comprised the measurements of the atresic side compared to those of the healthy side.
  
  
  RESULTS
  There was no significant difference between the atresic and healthy side of the nose in patients with CA with respect to mucosal thickness and volume of the PNS (the maxillary, frontal and sphenoidal sinuses) and the middle and inferior turbinate (p > 0.050).
  
  
  CONCLUSIONS
  The complete absence of nasal unilateral airflow had no effect on the development of the PNS and the middle and inferior turbinate. Moreover, mucosal thickness in the sinuses was similar to that in the control group.
