文献记载新生儿鼻偏斜有二类型,其一为生后第1天即可用闭合法复位于中线的鼻中隔尾端脱位,发生率约2％～23％,常同时伴有鼻小柱偏斜、前孔不对称性变形、鼻尖偏位,发生原因为与生产有关的多种因素(如胎位,产程,孕次,产钳使用不当);另一型与产伤无关而可能与“宫内损伤”有关,发生率约为0.4％～0.53％,这类偏歪于出生后即日不能被复位。对14例后一类型的患儿做11～12年的前瞻性研究,观察其自发变化过程。对1980～1981年2年间在U1m大学医院出生的3 425名新生儿,于生后1～4天内行耳鼻喉科检查。发现29例(0.86％)有不能复位的鼻偏斜,15例失访,另14例经11～12年后获随访,81例(2.37％)
There are two types of nasal degeneration reported in the literature, one of the first days after birth can be used to close the middle of the closure of the nasal septum dislocation, the incidence of about 2% to 23%, often accompanied by collimator skew , Asymmetrical deformation of the anterior orifice, deviation of the nose tip due to a variety of factors related to production (such as fetal position, labor process, pregnancy times, forceps improper use); the other type and birth injury may be related to “intrauterine injury ”, The incidence of about 0.4% ~ 0.53%, such deviation in the day after birth can not be reset. Fourteen cases of the latter type of children do 11 to 12 years of prospective study to observe the spontaneous changes in the process. A total of 3 425 newborns born at U1m University Hospital during the two years between 1980 and 1981 underwent otolaryngology examinations within 1 to 4 days after birth. In the study, 29 patients (0.86%) had nasal deviation that could not be reset, 15 patients lost follow-up, and the other 14 patients were followed up from 11 to 12 years later. 81 patients (2.37%
