下鼻甲粘膜下凝固术对鼻气道阻力的影响

目的 :观察下鼻甲粘膜下凝固术对鼻气道阻力的影响。方法 :应用主动性前鼻测压法 ,测定 17例慢性鼻炎患者 ,行下鼻甲粘膜下凝固术前后鼻气道阻力和主观鼻开放感觉评分情况。结果 :鼻炎组 17例患者术前鼻气道阻力是 (0 .6 6 7± 0 .2 1) k Pa· s/ L;术后 3个月 (0 .30 2± 0 .17) k Pa· s/ L,10个月 (0 .397± 0 .2 5 ) k Pa· s/ L,统计学显示术后两者和术前的差异有极其显著性意义 (P <0 .0 1)。术前主观鼻开放感觉评分是 7.5± 1.5 ,术后 3个月 2± 2 .0 ,10个月 3± 2 .5 ,两者和术前相比差异亦有极显著性意义 (P <0 .0 1)。结论 :下鼻甲粘膜下凝固术可显著性地降低患者的鼻气道阻力 ,同时可明显的改善患者的主观鼻开放感觉。

The effect of submucosal diathermy to the inferior turbinates on nasal airway resistance

OBJECTIVE: The main purpose of the study is to observe the effect of submucosal diathermy to the inferior turbinates on nasal airway resistance (NAR). METHOD: Using active anterior rhinomanometry, NAR were measured in seventeen patients who suffered from chronic rhinitis before and post operation. The subjective impression of their nasal patency was assessed using a 10-point scale. RESULT: The NAR is(0.662 +/- 0.22) kPa.s/L before operation and (0.302 +/- 0.17) kPa.s/L three months after operation. The NAR is 0.397 +/- 0.25 ten months after operation. The differences are statistically significant (P < 0.01) between the NAR before and post operation. There are significant differences in the subjective impression of patients' nasal patency as well (P < 0.01). CONCLUSION: Submucosal diathermy to the inferior turbinates is effective in decreasing NAR and improving the subjective impression of their nasal patency.
