摘　　要：目的探讨锥形束计算机体层摄影术(CBCT)在口腔颌面部囊性疾病诊断中的临床价值。方法收集53例颌骨囊性病变病例的CBCT影像资料,利用CBCT三维影像重建技术,观察颌骨囊性病变与牙根累及的关系、牙根吸收情况、病变内含牙、以及病变与下颌神经管、鼻底、上颌窦的关系等,并在术中进行验证。结果 CBCT能清晰的显示颌骨囊性病变与牙根的相互累及关系,埋伏牙相关信息以及病变与颌骨内重要结构的空间位移情况。结论 CBCT扫描能够全面提供颌骨囊性病变的影像学信息,可为颌面外科的临床手术提供可靠依据。Objective To investigate the clinical significance of cone-beam computed tomography （CBCT） in the diagnosis of maxil-lofacial cystic diseases. Methods CBCT images from 53 cases who suffered from jaw cystic disease were collected. CBCT three-dimen-sional image reconstruction technique was used and the involvement of roots, information of impacted teeth and anatomic relationship be-tween the lesions and mandibular canal, nasal floor, maxillary sinus were observed and analyzed preoperatively and verified during the operations. Results The involvement of roots,information of impacted teeth and anatomic relationship were clearly displayed in CBCT images. Conclusions CBCT can produce complete image information of jaw cystic diseases,thus its application might be a great sup-port for clinical operation.
