【摘要】 目的:通过对鼻中隔偏曲患者与对照者的鼻腔CT测量资料进行对照研究,探讨CT在评价鼻腔通气功能方面的临床意义。方法:鼻中隔偏曲患者26例(偏曲组),健康者15例(对照组)。采用CT对前鼻孔到后鼻孔的区域连续扫描,应用图像处理软件测量鼻腔各项通气参数,比较鼻中隔偏曲患者与对照者之间各测量参数的差别。结果:①通过t检验,偏曲组与对照组间鼻腔最小横截面积(NMCSA)、下鼻甲最大横截面积(IMCSA)、鼻腔最小横截面积到下鼻甲前端的距离(DNCAT)、下鼻甲最大横截面积到下鼻甲前端的距离(DICAT)有显著差异;鼻中隔偏曲伴对侧鼻塞组与对照组间偏曲对侧鼻腔最小横截面积(ONMCSA)和偏曲对侧鼻腔最小横截面积到下鼻甲前端的距离(ODNCAT)有显著差异;鼻中隔偏曲不伴对侧鼻塞组与对照组间ONMCSA无显著差异,ODNCAT有显著差异。②对偏曲组NMCSA与IMCSA进行双变量斯皮尔曼相关双侧检验,两者相关系数为-0.394,P<0.05。结论:CT是一种客观检查鼻腔通气功能的方法。通过对鼻腔形态学指标及功能性指标的测量可以更加全面地了解鼻腔的通气功能,从而使鼻阻塞性疾病的诊断及治疗更加科学化。更多还原

【Abstract】 Objective:To compare the CT scan results in patiens with deviation of nasal septum and normal adults and to explore its values in evaluating the state of nasal ventilation.Method: Twenty-six patients with deviation of nasal septum and 15 normal people were recruited in the study.The nasal airway from antetior nostril to posterior nostril was evaluated with PhlipsTomos scan AV Expander Elspiral scanner.The indexes of nasal ventilation was measured with the image-analysis software.The results of CT scan between patients with deviation of nasal septum and normal people was compared.Result: ①There was obvious difference between patients with deviation of nasal septum and normal people in the NMCSA,IMCSA,DNCAT and DICAT.There was obvious difference between patients with deviation of nasal septum with obstruction in the opposite side and normal people in the ONMCSA and ODNCAT.There was obvious difference between patients with deviation of nasal septum without obstruction in the opposite side and normal people in the ODNCAT.②In the patients with deviation of nasal septum,between nasal minimal cross sectional area and inferior turbinate′s maximum cross sectional area,there is obvious relation,r=-0.394,P<0.05.Conclusion: CT is one kind of objective inspection method in evaluating the state of nasal ventilation.With the measurement of the nasal morphology and functional index,we can understand the state of nasal ventilation more comprehensively.And with this,the treatment and diagnosis of disease with nasal obstruction will be more scientific.更多还原
