[Comparison of the nasal sinus development of children with or without sinusitis in Yunnan province].

Objective: To investigate the nasal sinus development and discuss the relation between sinusitis and nasal development.

Method: One thousand seven hundred and five healthy children and 1424 children with sinusitis were selected randomly. All children underwent naso sinus computer tomography. Sagittal, coronal and transverse diameters of all sinuses were measured and statistically analyzed.

Result: The measured sinus diameters of children with sinusitis were longer than that of healthy children (P < 0.01). Pearson analyses revealed a low correlation of age and the history of sinusitis (P < 0.01), and no correlation of gender and the history of sinusitis. There was moderate to high consistency between clinical diagnosis and nasal CT results about sinusitis (P < 0.01).

Conclusion: These results demonstrated that the differences of sinus development exist between the healthy children and children with sinusitis, and the sinus development in children with sinusitis were better than that of healthy children.
