文题释义
口咽部气道最窄距离测量:于颈椎侧位X射线片上分别找出悬雍垂及会厌的软组织影,并在悬雍垂下缘及会厌上缘各作一平行线,在两平行线直接找出气管影的最窄距离并进行测量。
寰枢椎脱位:寰枢椎脱位是指先天畸形、创伤、退变、肿瘤、感染炎症和手术等因素造成的寰椎与枢椎(C1和C2)骨关节面失去正常的对合关系,发生关节功能障碍和(或)神经压迫的病理改变。
 
摘要
背景:行寰枢椎后路内固定存在吞咽困难、呼吸困难甚至气道梗阻等情况,但目前未找到十分明确的影响口咽部气道空间狭窄的因素。
目的:分析寰枢椎脱位患者行后路复位内固定后影响口咽部气道最窄距离的因素。  
方法:纳入难复性单纯寰枢椎脱位并行后路寰枢椎内固定患者40例,所有患者对治疗方案均知情同意,且得到医院伦理委员会批准。分别测量术前及术后中立位颈椎侧位X射线片的口咽部气道最窄距离、寰齿间隙、颅底枢椎角、椎前软组织厚度及C2-C6角度,并分析术后各数据的变化及其对口咽部气道最窄距离的影响。  
结果与结论:①患者术后除C2-C6角及椎前软组织厚度外,各项指标数据与术前相比差异均有显著性意义(P < 0.01),其中口咽部气道最窄距离、寰齿间隙减小,颅底枢椎角增大;②其中对口咽部气道最窄距离变化影响最大的是寰齿间隙(β=0.524)及颅底枢椎角(β=0.477);③结果表明,寰枢椎脱位患者行后路复位内固定可能会出现口咽部气道狭窄,尤其对于术前寰椎明显脱位的患者,需加强监护,防止呼吸困难及吞咽困难情况发生。

Abstract:

BACKGROUND: The posterior atlantoaxial internal fixation may also cause dysphagia, dyspnea and even airway obstruction, but there is no clear factor affecting the stenosis of oropharyngeal airway.
OBJECTIVE: To investigate the effect of posterior internal fixation surgery for atlantoaxial dislocation on the oropharyngeal airway space.
METHODS: Forty patients with atlantoaxial dislocation under posterior internal fixation surgery were retrospectively included. All patients signed informed consent. This study was approved by the Hospital Ethics Committee. The narrowest oropharyngeal airway space, atlantodental interval, occipito-C2 angle, prevertebral soft tissue thickness and C2–C6 angle were measured in lateral cervical plain radiographs of neutral position before and after operation. The changes of postoperative data and their effects on the narrowest oropharyngeal airway space were analyzed.
RESULTS AND CONCLUSION: (1) Except C2–C6 angle and prevertebral soft tissue thickness, other data were significantly different after operation compared with those before operation (P < 0.01). Among them, the narrowest oropharyngeal airway space and atlantodental interval were reduced; and occipito-C2 angle was increased. (2) The atlantodental interval (β=0.524) and occipito-C2 angle (β=0.477) had the greatest effect on the narrowest oropharyngeal airway space. (3) Results suggested that posterior reduction and internal fixation of atlantoaxial dislocation patients may lead to oropharyngeal airway stenosis. Especially for patients with obvious atlantoaxial dislocation before operation, intensive monitoring is needed to prevent dyspnea and dysphagia.
