摘　　要：目的借助MRI图像分析患儿副鼻窦的最初气化时间，为副鼻窦相关疾病的诊疗提供影像学信息。方法回顾性分析2009年1月至2011年2月温州医学院附属第二医院行头颅MR检查的799例患儿头部平扫MRI图像，男430例、女369例，年龄0～15岁。观察各组副鼻窦的气化时间。结果筛窦发育气化最早，1个月内气化率100％（46／46），所有观察对象中未发现尚未气化者。其次为上颌窦，第1个月时气化率为45．7％（21／46），在7～12个月间气化率达97．8％（45／46）。蝶窦在第4个月可见气化，在1～2岁间气化率为86．O％（43／50）。额窦最初气化时间最晚，在1～2岁间气化率为8％（4／50），14～15岁气化率增至97．7％（42／43）。结论MRI能用于观察患儿副鼻窦的气化情况。患儿各组副鼻窦的最初气化时间较以往文献报道的早。Objective To evaluate the onset of initial pneumatization of paranasal sinuses with magnetic resonance imaging （ MRI ） and provides references in the diagnosis and treatment of pediatric paranasal sinuses disease. Methods The MRI images of paranasal sinuses were retrospectively reviewed for 799 children of 0 month to 15 years old and the first pneumatization time of paranasal sinuses were analyzed. Results The ethmoidal sinnse was the first pneumatized in 100% （46/46）of newborn children. And 45.7% （21/46）of maxillary sinuse showed penumatization during the first month of life and 97.8% （45/46）were pennmatized at 7 - 12 months. The penumatized sphenoid sinuse was first identified as early as 4 months. And 86% （43/50） were penumatized from 1 to 2 years old. Frontal sinuse was the last pneumatized paranasal sinuse. And 8% （4/50）of frontal sinuse were penumatized at 1 -2 years old and 97.8% （42/43） showed pneumatization at 14 - 15 years old. Conclusion MRI may be used to observe the pneumatization of paranasal sinuses. The initial pneumatization time of paranasal sinuses is earlier than previously described.
