观察121例习惯性鼻衄者,鼻衄次数2年中每年4次以上,70％12次以上。平均年龄40岁(8～76岁),男61％,女39％。同时选择121例年龄、性别相同、因耳鼻咽喉其他疾病而住院的病人作为对照组,其中近2年每年鼻衄1～3次者18例,其余103例平均每年出血不到一次。在表麻和收缩后检查鼻腔和鼻咽部,其粘膜改变有静脉曲张、小血管网、单个毛细血管瘤、多发性毛细血管瘤、血管异常、干性前鼻炎、中隔穿孔、粘膜萎缩。结果:121例习惯性鼻衄中可见161种上述改变,仅见一种改变者82例,有2种改变者35例,有3种改变者3例,一例鼻粘膜完全无上述改变;最常见的复合病变是静脉曲张加干性前鼻炎(17例)以及静脉曲张加单个毛细血管瘤(13例)。对照组中,可见到58种上述改变,只限于静脉曲张和干性鼻炎、4例同时有这两种改变。既有血管异常又有粘膜萎缩的发病率出血组明显高于对照组,仅有粘膜萎缩而无血管异常的发病率两组相同。在习惯性鼻衄
121 cases of habitual nasal obstruction were observed, the number of epistaxis in 2 years more than 4 times per year, 70% 12 times or more. The average age of 40 years (8 to 76 years), male 61%, female 39%. At the same time, 121 patients with the same age and gender who were hospitalized for other diseases of otolaryngology were selected as the control group. Among them, 18 cases were treated with epistaxis 1 ~ 3 times in the recent 2 years and the other 103 cases were bleeding less than once per year. Nasopharynx and nasopharynx were examined after ephedrine and contractility. The mucosal changes were varicose veins, small vascular network, single capillary hemangioma, multiple capillary hemangiomas, vascular abnormalities, dry anterior rhinitis, septal perforation and mucosal atrophy. Results: Among the 121 cases, there were 161 kinds of changes in habitual epistaxis. There was only one kind of change in 82 cases, two kinds of change in 35 cases, three kinds of change in three cases, and one case of nasal mucosa without the above changes. The most common Combined lesions were varicose veins plus dry anterior rhinitis (17 cases) and varicose veins plus a single capillary hemangioma (13 cases). In the control group, 58 of the above changes were seen, limited to varicose veins and dry rhinitis, with both of the four changes. Both vascular abnormalities and mucosal atrophy incidence of bleeding was significantly higher than the control group, only mucosal atrophy and no vascular abnormalities in the incidence of the same two groups. In habitual epistaxis
