阴唇粘连多发生于3个月至3岁的婴幼儿,2岁者约占56％。临床上以小阴唇粘连最常见,偶见大小阴唇同时粘连者。1 病因1.1 后天性原因 多数学者认为,阴唇粘连为后天性。出生后,上阴唇上皮生长在很大程度上受母体遗留下来的雌激素影响。出生后不久,来源于母体的雌激素水平下降,小阴唇上皮既嫩又薄,容易受损而导致损伤性粘连。婴儿期使用尿布(尤其是尿布外面有橡皮布或塑料布)者,由于阴部温度及湿度增加,容易导致阴唇上皮细胞脱落而致感染;穿开裆裤者,由于外阴暴露,亦易受感染。大便后揩擦肛门不当、大便污染外阴等,亦为感染性粘连的原因。1.2 先天性原因 有学者认为,胚胎发育过程中两阴唇可因不正常的融合而粘连,但此说法尚缺乏足够的理论依据。先天性阴唇粘连罕见,确诊前需排除两性畸形。2 诊断
Labia adhesions occurred in infants and children more than 3 months to 3 years old, about 56% of 2-year-old. Clinically, the most common labia minora adhesions, occasional size labia adhesion at the same time. 1 cause 1.1 cause of nature Most scholars believe that labia adhesion is acquired. After birth, the epithelium of the labia is largely affected by maternal estrogen. Shortly after birth, estrogen levels from the maternal decreased, the labia minora labellum tender and thin, easily damaged and lead to damage adhesions. Infant use of diapers (especially diapers or blankets outside the cloth) who, due to increased genitalium temperature and humidity, easily lead to labia epithelial cells shedding infection; wear crotch pants, due to exposure of the vulva are also susceptible. Improper stool rubbing anus, stool contamination of the vulva, etc., is also the cause of infectious adhesions. 1.2 causes of congenital Some scholars believe that during the embryonic development of both labia majora due to abnormal fusion and adhesion, but this argument is still lack of sufficient theoretical basis. Congenital labial adhesions rare, to be ruled out prior to diagnosis of genital hernia. 2 diagnostic
