Congenital ovarian dysplasia is also known as Turner syndrome. Early manifestations include slow height growth and short stature, and puberty manifests as secondary sexual characteristics dysplasia. Adult height is usually less than 150 cm. The typical child’s physical features include multiple moles, droopy eyelids, low ear size, high palatal arch, low posterior hairline, short and wide neck, webbed neck, barrel or shield-shaped chest, widely spaced nipples, underdeveloped breasts and nipples, and elbow valgus. The early appearance of atypical children is not significantly different from that of normal children. It is often associated with malformations of renal development and aortic arch stenosis. The disease is mainly caused by chromosomal abnormalities, and typical children show one less X chromosome than normal girls. There can be multiple chimerisms, such as 45, X/46, XX, 45, X/47, XXX. or 45, X/46, XX/47, XXX. The clinical presentation varies according to which cell lineage is predominant in the chimerism. If normal sex chromosomes are in the majority, there are fewer abnormal signs; conversely, if abnormal chromosomes are in the majority, there are more typical abnormal signs Turner syndrome can also be due to abnormal sex chromosome structure, such as deletion of the long or short arm of the X chromosome, forming a loop or translocation. The clinical presentation is related to the number of deletions. Those with deletions may still have residual follicles and may have menstrual flow, followed by amenorrhea after a few years. In childhood, congenital ovarian dysgenesis is mainly characterized by short stature and other symptoms are usually not obvious. Most congenital ovarian dysplasia was previously seen in obstetrics and gynecology after the girl reached adulthood due to lack of menstrual flow. Because of the late consultation, the girl misses the developmental stage of her height, resulting in a short stature and poor secondary sexual characteristics, which has a great impact on her physical and mental health. Congenital ovarian dysplasia is one of the more serious diseases that lead to short stature in girls. Parents should regularly monitor their children’s height development and find the cause of abnormal height development as soon as possible. The height clinic of our child health department specializes in the standardized diagnosis and treatment of children with abnormal height development. Based on the scientific assessment of the bone age and sexual development level of these children, the rational application of growth hormone and sex hormone treatment can maximize the adult height and secondary sexual characteristics of these children and maintain their menstrual cycle in late adolescence. A small number of these children can become pregnant naturally in adulthood, but their fetal development needs to be strictly evaluated. Warm tip: It is best to visit the clinic for children with short stature on an empty stomach. The height clinic of the Department of Child Health is located on the second floor of the Health Building, Room 21.
