Lateralization of primary epistaxis was prospectively studied in 326 patients at Radebeul Elblandklinikum. The male-female-ratio was 1.3:1. A slight dominance of the right side (45% right vs. 39% left) was found in all patients. Further analyzed were the relationship to the localization of bleeding (anterior or posterior), the age and possible causes or risk factors. Nose bleeding from the posterior nasal portion appears to be statistically significantly higher than on both sides of anterior epistaxis. No statistically significant age dependence of laterality of epistaxis was observed in the age groups which we selected. However, nosebleed appears more frequently in women under the age of 50 years in both nostrils. With identified risk factors, idiopathic epistaxis occurs more frequently on the right side than does nosebleed. Mechanical trauma (intranasal sprays or nose picking) is a possible factor explaining the dominance of epistaxis on the right side, especially in idiopathic cases.
在拉德博伊尔 Elblandklinikum，我们前瞻性地研究了 326 名原发性鼻出血患者的偏侧性。男女比例为 1.3:1。所有患者均发现右侧轻微优势（45%右侧 vs. 39%左侧）。进一步分析了出血部位（前或后）、年龄以及可能的病因或危险因素之间的关系。来自后鼻道的鼻出血明显多于前鼻出血的两侧。我们选择的年龄组中，未观察到鼻出血偏侧性与年龄有统计学显著相关性。然而，50 岁以下的女性双侧鼻出血更为常见。在确定了危险因素后，特发性鼻出血比鼻出血更常发生在右侧。机械性创伤（鼻腔喷雾或挖鼻）可能是导致右侧鼻出血优势的一个因素，尤其是在特发性病例中。
