摘要
目的 探讨MSCT辅助OMENS评分法对半侧面部短小症（HFM）形态学改变的评价情况.方法 选取行MSCT检查的HFM患儿11例,对采集数据进行MPR、MIP及VR图像重组,结合OMENS评分法对HFM各主要畸形进行独立评价.结果 11例患儿中,9例为单侧发病,其中左侧6例,右侧3例.双侧发生者2例,双侧严重程度不等,1例以右侧为著,1例以左侧为著.利用OMENS评分法对11例患者的所有畸形进行逐一评价,均得到了满意的结果.其中颧弓-眼眶畸形累及8例8侧,耳廓畸形累及11例13侧,下颌骨畸形累及9例10侧,软组织畸形累及11例12侧.结论 采用MSCT辅助的OMENS评分法,能够比较全面而准确地对HFM累及的面部畸形进行形态学评价,为临床全面评价该病提供有力的影像学支持.
Objective To assess the value of the multi-slice CT based OMENS classification in diagnosing pediatric hemifacial microsomia. Methods Eleven patients including 9 boys and 2 girls with suspicion of hemifacial microsomia underwent MSCT. Multi-planar reformation （MPR）, maximum intensity projection （MIP） and volume-rendered image （VR） reconstruction were performed at the workstation. The malformations of the facial structures were analyzed respectively with the OMENS classification system.Results On CT reconstruction images, hemifacial microsomia in all 11 patients was demonstrated clearly.Nine patients were found to have unilateral lesion, including 6 on the left side and 3 on the right side. Two patients presented bilateral involvement with various severity degree. The OMENS classification system can be perfectly used to analyze the deformities. Respectively, the orbit and zygomatic arch deformity involved 8 sides in 8 cases, the mandible deformity involved 10 sides in 9 cases, the auricular deformity involved 13 sides in 11 cases, and the soft tissue deformity involved 12 sides in 11 cases. Conclusion MSCT based OMENS classification system can make accurate and comprehensive evaluation of the morphological changes in hemifacial microsomia, which provide strong imaging evidence to clinical evaluation.
