A variety of congenital syndromes affecting the face occur due to defects involving the first and second BAs. Radiographic evaluation of craniofacial deformities is necessary to define aberrant anatomy, plan surgical procedures, and evaluate the effects of craniofacial growth and surgical reconstructions. High-resolution CT has proved vital in determining the nature and extent of these syndromes. The radiologic evaluation of syndromes of the first and second BA should begin first by studying a series of isolated defects (cleft lip with or without CP, micrognathia, and EAC atresia) that compose the major features of these syndromes and allow a more specific diagnosis. After discussion of these defects and the associated embryology, we discuss PRS, HFM, ACS, TCS, Stickler syndrome, and VCFS.
多种涉及第一和第二鳃弓的先天性综合征会影响面部。为了明确异常解剖结构、规划手术流程以及评估颅面生长和外科重建的效果，有必要对颅面畸形进行放射学评估。高分辨率 CT 已被证明对确定这些综合征的性质和范围至关重要。首先，应对第一和第二鳃弓综合征进行放射学评估，研究一系列构成这些综合征主要特征的孤立性缺陷（唇裂伴或不伴腭裂、小颌畸形和外耳道闭锁），从而做出更明确的诊断。在讨论这些缺陷及其相关胚胎学之后，我们将讨论 PRS、HFM、ACS、TCS、Stickler 综合征和 VCFS。
