本文介绍部分胎儿及新生儿口腔前庭粘膜所见的与正常粘膜色泽相同的乳头状突起的观察结果。资料包括22例胎儿与4例新生儿的尸体及287例新生儿的口腔前庭粘膜所见。287例新生儿中粘膜有乳头状结构者120例。男性142例中阳性者61例(42.9％);女性145例中阳性者59例(40.7％)。男女总例数与阳性数之比均约1:1,无明显性别差。此结构在上、下唇的分布不均,下唇多于上唇,双侧基本对称。从随访及胎儿的观察结果表明此结构在妊娠3～4个月即已出现,随孕龄增长乳头逐渐发育生长,其表面被覆与周围相延续的鳞状上皮,有毛细血管及结缔组织伸入组成中轴,其结构与舌背丝状乳头相似,在生后10天左右此结构即渐消退。对此结构我们尚未在书刊中查到有关资料,其生物学意义有待于进一步探讨。
This article describes some of the fetus and neonatal oral vestibular mucosa seen with the same color of normal mucous papillae findings. The data included 22 corpses of fetuses and 4 newborns and oral vestibular mucosa of 287 newborns. There were 120 cases of papillary structures in 287 newborn infants. Among 142 males, 61 were positive (42.9%), while 145 were males (59.7%). The total number of male and female cases and the positive number ratio of about 1: 1, no significant gender difference. This structure in the upper and lower lip unevenly distributed, lower lip than the upper lip, both sides of the basic symmetry. From the follow-up and fetal observation results show that this structure has emerged in 3 to 4 months of pregnancy has emerged with the growth of the growing nipple growth, the surface covered with the surrounding continuous extension of the squamous epithelium, capillaries and connective tissue extension The composition of the central axis, the structure of the tongue with the back of the nipple similar to 10 days after birth, this structure is gradually subsided. This structure we have not found in the books and information, its biological significance needs further study.
