鼻声反射指导下鼻腔扩容术的临床分析

Clinical Analysis of Nasal Cavity Expansion according to Acoustic Rhinometry

目的:观察并探讨鼻声反射技术在指导鼻内镜下鼻腔扩容术中的作用和临床疗效。方法:随机选取某院采用鼻声反射指导下鼻腔扩容术的105例鼻腔阻塞患者,对其临床资料和治疗效果进行回顾性分析,术前及术后3个月,患者需接受鼻声反射检查,对NV(鼻腔容积)、MCA(最小截面积)、MNCA(鼻腔平均截面积)以及鼻阻力(NR)进行计算,指导进行鼻腔扩容术,并进行统计学分析。结果:鼻腔平均截面积(MNCA)、鼻腔最小横截面积(MCA)、鼻腔容积(NV)检测结果术后较术前显著变大,鼻阻力(NR)较术前减小,3项指标的差异有统计学意义(P<0.05)。结论:鼻声反射可以很好地指导鼻腔扩容手术并可以作为术后效果的客观评价指标。

Objective：To observe and investigate the instructive and clinical effect of acoustic rhinometry on endoscopic nasal cavity expansion. Methods：Randomly select 105 patients with rhinostegnosis who had un- derwent nasal cavity expansion under the direction of AR, make retrospective analysis on their clinical data and curative effect,in the 3 months before and after the surgery,the patients had to be examined with AR, and NV （nasal volume）,MCA（minimal cross-sectional area）, MNCA（mean nasal cross-sectional area） and NR（nasal resistance） were worked out to instruct nasal cavity expansion , made statistical analysis. Results： Postoperative MNCA,MCA and NV were found to be larger than that of pre-operation,and NV had become lower than before, the differences of the three indexes were statistically significant（P^0.05）. Conclusion：It is possible for acoustic rhinometry to guide nasal cavity expansion well and it can be an objective evaluation in- dex of effect after the surgery.
