摘　　要：本文分析了 5 6例飞行员寰椎椎动脉沟环的X线表现 ,根据X线形态 ,将其分为三型 :Ⅰ型为完整形沟环 ,32例 ,可为单侧完全型或双侧完全型 ,也可为一侧完全型而另一侧为不完全型 ;Ⅱ型为不完整型或半环型 ,18例 ,分Ⅱa和Ⅱb两型 ,Ⅱa型 4例 ,也称前半环型 ,Ⅱb型 14例 ,称后半环型 ;Ⅲ型为断环型 ,6例。认为寰椎椎动脉沟环为颈椎解剖结构变异 ,与颈性眩晕有一定关系 ,在选拔飞行学员时应注意该变异的存在。The presence of the cervical artery sulcus ring was found on the atlas in 56 out of 346 air pilots. The X ray appearance could be classified as follows. Type Ⅰ:Complete sulcus ring in 32 cases, in whom the sulcus might be complete unilaterally or bilatrally. Type Ⅱ: Incomplete or half ring in 18 cases. This type could be further divided into Ⅱ a , consisting of 4 persons with half ring in the anterior aspect, andⅡ b , half ring posteriorly in14 persons. Type Ⅲ: Broken ring in 6 persons. It is an anatomic variation, which may be have some relationship to vertigo. It is suggested that the presence of cervical artery sulcus ring on atlas should be taken as an disqualification factor in air pilot recruitment.
