The movements of the upper cervical spine were measured by fluoroscopy in 20 patients during laryngoscopy with the Bonfils intubation fibrescope and the Macintosh laryngoscope. Laryngoscopy with both the Bonfils intubation fibrescope and the Macintosh laryngoscope resulted in significant extension of the cervical spine as compared to the neutral position but this extension was significantly less with the Bonfils intubation fibrescope than with the Macintosh (p = 0.001). However, the atlanto-occipital distance was significantly greater during laryngoscopy with the Bonfils intubation fibrescope (p = 0.002), and the angle between the occiput and C1 differed significantly between the two techniques (p = 0.001). With the Bonfils intubation fibrescope, significantly less extension was also found at the C1/C2 and C3/C4 levels (p = 0.001 and p = 0.049, respectively). There is therefore significantly less movement of the upper cervical spine during laryngoscopy with the Bonfils fibrescope compared with the Macintosh laryngoscope.
在20例患者使用邦菲尔斯插管纤维喉镜和麦金托什喉镜进行喉镜检查期间，通过荧光透视法测量上颈椎的活动度。与中立位相比，使用邦菲尔斯插管纤维喉镜和麦金托什喉镜进行喉镜检查均导致颈椎明显伸展，但邦菲尔斯插管纤维喉镜引起的伸展明显小于麦金托什喉镜（p = 0.001）。然而，使用邦菲尔斯插管纤维喉镜进行喉镜检查时寰枕距离明显更大（p = 0.002），并且两种技术之间枕骨与C1之间的角度存在显著差异（p = 0.001）。使用邦菲尔斯插管纤维喉镜时，在C1/C2和C3/C4水平也发现伸展明显较少（分别为p = 0.001和p = 0.049）。因此，与麦金托什喉镜相比，使用邦菲尔斯纤维喉镜进行喉镜检查时上颈椎的活动明显较少。
