阴唇粘连症较常见于幼女,是外阴炎和外阴阴道炎的一种后遗症。一、诊断:本病是在会阴特别是左右小阴唇内侧有一薄膜样粘连,粘连范围很不一致,可以从阴带下部直到阴唇后联合。本病的诊断名称有多种记载,如阴唇粘连症(Labia1 adhesion)阴唇融合症(Labial fusion)等,但后者应与阴唇粘连症相区别。阴唇融合症属于先天性畸形,由于胎儿期雄激素过多引起的性分化异常,如阴蒂明显肥大伴阴唇高度融合时,则恰似阴囊外观,有时会误诊其性别。阴唇粘连症是后天发生的小阴唇膜样粘连,膜的下方有正常的处女膜及阴道,常伴阴蒂包皮粘连,需要与处女膜闭锁及无阴道等鉴别。幼女因雌激素少,外阴菲薄,抵抗力低,加上会阴的可动性小,左右阴唇接近,一但上皮剥脱形成糜烂,则易于粘连而发病。二、发病时期:本病多发生于雌激素低下的婴 Labia adhesion is more common in young girls, is a sequelae of vulvitis and vulvovaginitis. First, the diagnosis: The disease is in the perineal especially around the labia minora with a thin film-like adhesions, adhesion is very inconsistent range, from the lower part of the genitals until the labia after joint. Diagnosis of the disease there are many different names, such as Labia adhesion (Labia1 adhesion) labial fusion, etc., but the latter should be distinguished from labial adhesions. Labia fusion is a congenital malformation, due to abnormal fetal androgenic differentiation caused by abnormal, such as the clitoris was significantly hypertrophic with a high fusion of the labia, then the appearance of the scrotum, and sometimes misdiagnosed their gender. Labia adhesion is acquired labial labia minora adhesions, the film has a normal hymen and vagina below, often accompanied by clitoris foreskin adhesions, and hymen atresia and no need to identify the vagina. Young girls due to less estrogen, thin vulva, low immunity, coupled with the mobility of the perineum is small, around the labia minora, but the formation of epithelial exfoliation erosion, it is easy to adhesion and disease. Second, the onset of the disease: the disease occurred in estrogen low infants
