    Abstract:
    Objective:To analyze the anatomical and developmental characteristics of nasal sinuses in 2-3 years old children.Method:Coronal CT scans of 62 cases (2-3 years old children) were studied with the imaging station. The gasification conditions of the sinuses were identified and measured.Result:The mean of the transverse and vertical diameters for the left side of the maxillary sinuse was (17.51±2.92)mm and (16.63±3.46)mm. Those for the right side were (17.28±2.51)mm and (17.24±3.72)mm. The mean for the left side of the anterior ethmoid sinus were (5.06±1.18)mm and (13.61±2.49)mm. Those for its right side were (5.00±1.45)mm and (13.64±2.30)mm. The mean for the left side of the posterior ethmoid sinus were (7.94±1.72)mm and (12.80±1.78)mm. Those for the right side were (7.88±1.85)mm and (12.64±.96)mm.96.77%(120 sides) of the sphenoid sinuses were developed. The mean for the left side of the sphenoid sinus were (7.38±3.11)mm and (8.67±3.14)mm. Those for the right side were (7.48±2.70)mm and (8.63±2.42)mm. 30.65% (38 sides) of the frontal sinuses were developed.Conclusion:The all nasal sinuses in 2-3 years old children have been already developed. The pneumatization of the frontal sinus was defined in some babies. It can help radiologist make correct diagnosis of paranasal sinuses in children.
