| Abstrakt: | Background: Although the determinates of paranasal sinus development and sinusitis are not well defined, a candidate factor is blockage of the choana. Hypothesis: Maxillary sinuses ipsilateral to unilateral choanal atresia are comparatively small and have more evidence of sinusitis than do the contralateral sinuses. Design: Retrospective. Setting: Children's hospitals. Patients: Sixteen nonsyndomic children with isolated unilateral congenital choanal atresia. Main Outcome Measures: Determination of maxillary sinus volumes and mucoperiosteal thickening on preoperative computed tomograms. Results: Maxillary sinuses ipsilateral to unilateral choanal atresia have slightly larger volumes than, and mucoperiosteal thickening that is similar to, the contralateral sinuses. Conclusion: These data suggest that maxillary sinus development and sinusitis are independent of posterior nasal ventilation and drainage. |
