To evaluate the incidence and significance of radiographic sinus opacification in infants, we performed computed tomography (CT) of the maxillary and ethmoid sinuses in conjunction with routine cranial CT in 100 infants from birth to 12 months of age. CT was performed for indications other than sinusitis. Prospective concurrent clinical history was obtained and physical examination of the upper respiratory tract was performed. Of 100 infants, 16 had hypoplasia of the maxillary sinuses; 81% (13/16) of these were less than 2 months of age. The antra showed progressive increase in size during the first year of life. Of the 100 infants, 70 had CT sinus opacification, including 67% of those without historical or physical evidence of upper respiratory tract infection. There was a positive correlation of CT findings between the maxillary and ethmoid sinuses in 80% of the infants older than 2 months of age but in only 49% of the younger infants. Radiographic sinus opacification in infants is of uncertain significance and is not diagnostic of upper respiratory tract infection, much less of sinusitis.
为评估婴儿鼻窦影像学混浊的发生率及意义，我们对100名年龄从出生至12个月的婴儿，在进行常规头颅CT的同时进行了上颌窦和筛窦的计算机断层扫描（CT）。CT检查是因鼻窦炎以外的指征进行的。获取了前瞻性同期临床病史并对上呼吸道进行了体格检查。100名婴儿中，16名上颌窦发育不全；其中81%（13/16）年龄小于2个月。鼻窦在生命的第一年中显示出逐渐增大。100名婴儿中，70名有CT鼻窦混浊，包括67%无呼吸道感染病史或体格检查证据的婴儿。在2个月以上的婴儿中，80%上颌窦和筛窦的CT表现呈正相关，但在年龄较小的婴儿中仅为49%。婴儿鼻窦影像学混浊的意义尚不确定，不能诊断上呼吸道感染，更不能诊断鼻窦炎。
