Abstract:
Objective To investigate the effects of angle and length of lightwand in patients with ankylosing spondylitis (AS) using three-dimensional reconstruction based on computed tomography.Methods The head and neck helical computed tomography data of 53 patients with AS(AS group)and 60 common patients without cervical spine deformity (control group) were retrospectively analyzed.Reconstructed images, obtained by three-dimensional computed tomography reconstruction technique, were printed out by the ratio of 1:1.The endotracheal tube was used to simulate tracheal intubation in patient's computed tomography images.The length of tracheal tube from midpoint of glottis to upper central incisor(L),bend angle of tracheal tube(α),distance between the upper central incisor and root of epiglottis (D1) and distance between the root of epiglottis and midpoint of glottis (D2) were recorded.Results The α and D1in AS group were significantly bigger than those in control group:(89.57 ± 15.22)°vs.(67.65 ± 13.32)°and(8.11 ± 0.69)cm vs.(7.39 ± 0.58)cm,and there were statistical differences(P<0.05).There were no statistical differences in L and D2between 2 group(P>0.05).The α, L, D1and D2in male AS patients were significantly bigger than those in female AS patients:(90.78 ± 14.51)° vs.(81.57 ± 15.01)°, (12.84 ± 0.88)cm vs.(11.56 ± 1.17)cm, (8.18 ± 0.59)cm vs.(7.69 ± 0.64)cm and(3.22 ± 0.38)cm vs.(2.30 ± 0.29)cm,and there were statistical differences(P<0.05).Conclusions Compared with that of common patients, the bent angle on lightwand with AS patients is increased,which also can be affected by patients'gender.
