接触性头痛患者手术前后鼻气道阻力变化

Changes in nasal airway resistance before and after intranasal contact point headaches

目的:研究接触性头痛患者手术前后鼻气道阻力(NAR)的变化。方法:利用前鼻测压法对20例(40侧)接触性头痛患者手术前后、鼻减充血前后的NAR进行研究。结果:随访6个月,痊愈16例(85%),有效3例(15%),无效1例(5%),有效率95%。术后NAR明显下降,手术前术侧喷麻黄碱前后NAR分别为(-0.34±0.23)和(-0.75±0.21)kPa.s/L;手术后分别为(-0.68±0.20)和(-0.74±0.16)kPa.s/L,两者相比差异有统计学意义(P<0.05)。结论:内镜手术对接触性头痛患者鼻通气功能的改善主要是由于鼻腔结构的改变和黏膜肿胀的消退,测定NAR对于客观评价接触性头痛患者接触点的解除具有重要临床意义。

Objective： To study the influence of endoscopic sinus surgery （ESS）on nasal airway resistance （NAR） of intranasal contact point headaches. Method： The NAR and nasalairflow sensation were measured with anterior rhinomanometry in 20 patients（40sides） before and after the ESS. Result： A telephone follow-up six months after operation, 16 （85%） cases were cured, 3 （ 15 % ） were improved and 1 （5 % ） had no response and the effective rate was 95%. NAR decreased significantly after the operation. The change ratesin NAR before and after the decongestion were （-0.34±0.23）,（-0.75±0.21）and （-0.68±0.20）,（-0.74±0.16）kPa · s/L, respectively ,and there was a significant difference（P〈0. 05）. Conclusion： The improvement of nasal functions by ESS is due to theaheration of the anatomic structure of the nasal cavity and the amelioration of mucosal edema. The rhinomanometry can be used as a useful clinical tool in determining nasal patency.
