CT在鼻窦疾患诊断上的价值已经肯定。作者研究CT影象上颌窦壁肥厚的意义,辨明炎症引起的骨壁肥厚或人为假象。对X线平片和CT影象上颌窦壁的厚度进行比较;对比手术采取的上颌窦前壁和CT影象上颌窦前壁的厚度。观察慢性上颌窦灸11例(17侧)、正常上颌窦2例(2侧)。以眶下孔下方10mm处为中心取上颌窦前壁骨片,直径约10mm,测量骨片厚度为0.1mm。CT层面通过眶下孔下方10mm处,测定影象中上颌窦前壁的厚度,并探讨上颌窦内容物CT值对测量结果有何影响。结果:一侧慢性上颌窦炎,患侧骨壁较健侧为厚
CT in the diagnosis of sinus disease value has been affirmed. The author of the CT image of the significance of the maxillary sinus wall hypertrophy, identify inflammation caused by bone or hypertrophy of the artificial illusion. The thickness of the maxillary sinus wall in X-ray plain film and CT image were compared. The thickness of the anterior wall of maxillary sinus and CT image in the operation were compared. Chronic maxillary sinus moxibustion in 11 cases (17 sides), normal maxillary sinus in 2 cases (2 sides). Take 10mm below the infraorbital foramen as the center of the anterior wall of the maxillary antrum, a diameter of about 10mm, measuring the thickness of bone slices 0.1mm. The CT level was measured 10 mm below the infraorbital foramen to determine the thickness of the anterior wall of the maxillary sinus in the image and to investigate the effect of the CT value of the contents of the maxillary sinus on the measurement. Results: One side of chronic maxillary sinusitis, ipsilateral bone wall thicker than the healthy side
