鼻内镜和常规额镜下清除外耳道异物的效果比较

Comparison of effect in clearing external auditory canal foreign bodies with endoscopic and the conventional frontal lens

目的:比较常规额镜和鼻内镜下外耳道异物取出方法及效果。方法:2006年6月1日至2012年6月1日期间就诊本院耳鼻喉科的外耳道异物患者,其中2009年6月1日前(48例)、后(60例),分别在常规额镜和鼻内镜的显示照明下,通过吸引器吸出异物,或用耵聍钩钩出异物。分别比较一次成功率、平均耗时和疼痛患者比例。结果:分别有40例(83.3%)和57例(95%)患者一次成功取出异物。平均耗时分别为(3±0.45)min和(1±0.25)min。分别有9例(18.8%)和5例(8.3%)患者报告术中有明显疼痛。经统计学比较,一次成功率(p=0.046)和平均耗时(p=0.041)差异具有统计学意义。结论:鼻内镜是清除外耳道异物的有效方法,具有用时短、一次成功率高等优点。

Objective: To compare the effect of endoscopic and the conventional frontal lens in clearing external acoustic meatus foreign bodies. Methods: 148 outpatients with external auditory canal foreign bodies between 1st Jun 2006 and 1st Jun 2012 in our hospital were recruited; they received operations to clear their foreign bodies with the conventional frontal lens or endoscope, respectively. Then compare the success rate after one operation, average time-consuming and the proportion of patients with pain. Results: 40 and 57 patients respectively in the two groups succeed with one operation. The average time-consuming were (3±0.45) min and (1±0.25) min. There were 9(18.8%) and 5 (8.3%) patients reported intraoperative pain. The success rate after one operation and the average consuming time between the two groups have significant difference. Conclusion: Endoscope is the effective method to clear external acoustic meatus foreign bodies.
